Evaluate x - (y - z) and (x- y) - z for y = 3, x = 5, z = 4. Is there any associative property of subtraction
Answer:
There is no associative property of subtraction.
Step-by-step explanation:
Given:
x = 5y = 3z = 4x - (y - z) = 5 - (3 - 4) = 5 - (-1) = 5 + 1 = 6
(x - y) - z = (5 - 3) - 4 = 2 x -4 = -6
Therefore, there is no associative property of subtraction as 6 ≠ -6

Answer:
x = -2, y = -6
Step-by-step explanation:
(8x - 3y) + (-8x - 5y) = 2 + 46
-8y = 48
y = -6
8x - 3y = 2
8x - 3(6) = 2
8x + 18 = 2
8x = -16
x = -2
Answer:
[tex]\boxed { \sf (-2, -6) }}[/tex]
Step-by-step explanation:
We are asked to find the solution of the system of equations.
[tex]8x-3y=2\\-8x-5y=46[/tex]
When we solve systems of equations, we have to do 2 steps. The first step eliminates one variable so we can solve for the other. The next step helps us find the variable we canceled.
The first equation has the term 8x and the second equation has the term -8x. If these are added, they cancel, so we are left with the variable y. Add the equations together.
[tex](8x-3y=2) \\+ (-8x-5y=46)[/tex]
8x and -8x cancel, then add.
[tex](-3y=2)\\+ (-5y=46)[/tex]
___________
[tex]-8y= 48[/tex]
We are solving for y, so we must isolate the variable. It is being multiplied by -8. The inverse operation of multiplication is division. Divide both sides by -8.
[tex]-8y/-8=48/-8 \\y= 48/-8 \\y=-6[/tex]
Now we know what y is equal to, so we can plug it back into one of the original equations and solve for x.
I chose the first equation.
[tex]8x-3y=2[/tex]
[tex]8x-3(-6)=2[/tex]
[tex]8x+18=2[/tex]
Subtract 18 from both sides to isolate 8x.
[tex]8x+18-18=2-18\\8x=2-18\\8x=-16[/tex]
Divide both sides by 8.
[tex]8x/8=-16/8 \\x=-16/8 \\x= -2[/tex]

Step-by-step explanation:
the triangle is an Isosceles triangle
let the another two angles be 2x
and apply angle sum property of triangle here
2x + 72° = 180
2x = 180 - 72
2x = 108
x = 108/2 = 54
therefore,
angle 2 = 54°
a/q
angle 2 = -9 + 7x
now,
54° = -9 + 7x
or
-9 + 7x = 54°
7x = 54 + 9 = 63°
x = 63/7 = 9
x = 9
therefore, value of x is 9.

the length of a rectangle is 5 more than twice its width. its perimeter is 70 cm. what is its area? show your solution
Answer:
[tex]250cm^2[/tex]
Step-by-step explanation:
length = 5 + 2w
width = w
P = Sum of all sides
P = 2 * (5 + 2w) + 2w
P = 10 + 4w + 2w
P = 6w + 10
Given Perimeter = 70cm
We substitute
6w + 10 = 70
6w = 70 - 10
6w = 60
w = 60/6
w = 10cm
Since length is 5 + 2w
length = 5 + (2 * 10)
length = 25cm
Area = lw
Area = 25 * 10
Area = [tex]250cm^2[/tex]
Answer:
let
b=x then'
l= 2x+5
Now
p=70
2(l+b)=70
2(x+2x+5)=70
6x+10=70
6x=60
x=6
b=x=10
l=2x+5=25
area of rectangle = l*b

Madelyn is 1.85 meters tall. At 12 noon, she measures the length of a tree's shadow to be 39.75 meters. She stands 34.9 meters away from the tree, so that the tip of her shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest hundredth of a meter.
The relationship between her height and the tree's is an illustration of ratios and proportions
The height of the tree is approximately 2.11 meters
Her height is represented as:
[tex]\mathbf{h =1.85}[/tex]
At 12 noon, the length of the tree's shadow and her distance from the shadow are given as:
[tex]\mathbf{D =39.75}[/tex]
[tex]\mathbf{d =34.9}[/tex]
To calculate the height (H) of the tree, we make use of the following equivalent ratios
[tex]\mathbf{H : h =D : d}[/tex]
So, we have:
[tex]\mathbf{H : 1.85 =39.75 : 34.9}[/tex]
Express ratio as fraction
[tex]\mathbf{\frac{H }{ 1.85 }=\frac{39.75 }{ 34.9}}[/tex]
Multiply both sides by 1.85
[tex]\mathbf{H=1.85 \times \frac{39.75 }{ 34.9}}[/tex]
[tex]\mathbf{H=2.11}[/tex]
Hence, the height of the tree is approximately 2.11 meters

Im confused on this. Michael has some coins in his pocket consisting of dimes, nickels, and pennies. He has two more nickels than dimes, and three times as many pennies as nickels. How many of each kind of coin does he have if the total value is $0.52?
Answer:
Using a system of equations, it is found that he has 2 dimes, 5 nickels and 12 pennies.
In the system of equations, I am going to say that:
x is the number of dimes.
y is the number of nickels.
z is the number of pennies.
---------------------
Two more nickels than dimes, thus:
Three times as many pennies as nickels, thus:
---------------------
A dime is worth $0.1, a nickel is worth $0.05, and a penny is worth $0.01. Total of $0.52, thus:
Solving for x:

Solving for y and z:
He has 2 dimes, 5 nickels and 12 pennies.
The New York Nicks had a streaky season. They began by winning 4 games in a row, and then they lost 12 games in a row. After those 12 losses, they won every game, finishing with 3 wins for every 2 losses overall. How many games did they win after the first 16 games?
Using proportions, it is found that they won 14 games after the first 16 games.
This question is solved by proportions, using a rule of three.For each 3 games they won, they lost 2.They lost 12 games, all on the losing streak, and won x games.Hence, the rule of three is:
2 losses - 3 wins
12 losses - x wins
Applying cross multiplication:
[tex]2x = 3(12)[/tex]
[tex]x = \frac{36}{2}[/tex]
[tex]x = 18[/tex]
18 wins, being 18 - 4 = 14 after the first 16 games, hence, they won 14 games after the first 16 games.

C. a = 2 and b = 1.2
D. a = 1.2 and b = 2
Answer: None of the answers are viable.
Step-by-step explanation:
a ≅ 8b
a/b ≅ 8
A. (3.1/2.5) = only slightly greater than 1
B. 2.5/3.1 = slightly less than 1
C. (2/1.2) = less than 2
D. 1.2/2 = less than 1
None of these answers is viable.
None of the options are correct.
Given,
The number a is about 8 times greater than b.
We need to find the correct value of a and b from the given options.
A. a = 3.1 and b = 2.5
B. a = 2.5 and b = 3.1
C. a = 2 and b = 1.2
D. a = 1.2 and b = 2
What do the mathematical terms mean?We have,
2 times M = 2x M
2 greater than M = M + 2
2 less than M = M - 2
Sum = adding
Times = Multiplication
Find the value of a and b.
We have,
The number a is about 8 times greater than b.
We can write it as
a = 8 x b
Find out which option is correct.
A. a = 3.1 and b = 2.5
a = 8 x b
3.1 = 8 x 2.5
3.1 ≠ 20
So this option is incorrect.
B. a = 2.5 and b = 3.1
2.5 = 8 x 3.1
2.5 ≠ 24.8
This option is not correct.
C. a = 2 and b = 1.2
2 = 8 x 1.2
2 ≠ 9.6
This option is not correct.
D. a = 1.2 and b = 2
1.2 = 8 x 2
1.2 ≠ 16
This option is not correct.
Thus none of the options are correct.

Step-by-step explanation:
A company that manufactures golf balls produces a new type of ball that is supposed to travel significantly farther than the company’s previous golf ball. To determine this, 40 new-style golf balls and 40 original-style golf balls are randomly selected from the company’s production line on a specific day. The balls are then placed in a bag and shaken. A golf pro then selects a ball and hits it. The distance the ball travels is then measured. The bag is shaken again, and the golf pro selects another ball to hit. She continues this procedure until all 80 of the golf balls are hit.
Has the principle of comparison been addressed in this experimental design?
Yes, because the balls are randomly selected, the distances of the new ball can be compared to the distances of the original ball.
Yes, because the original ball type is included in this experiment, the distances the different balls travel can be accurately compared.
No, because a placebo ball was
The design of the experiment is such that the knowledge of the type of
ball being hit does nit influence the outcome of the experiment.
The correct option is; Yes, because the balls are randomly selected, the distance of the new ball can be compared to the distances of the original ball.Reasons:
The aim of the experiment is to determine if the new type of ball travels farther than the company's previous golf ball.
The design of the experiment is as follows;
Number of the previous golf ball in the experiment = 40
Number of the new type of golf ball used in the experiment = 40
The order in which the ball are selected from the bag = Randomly
The subject of the experiment = A golf pro
The sample size of each sample is larger than 30, and therefore, the
distribution can be taken as approximately normal.
The principle of comparison has been addressed in the experiment
because the golf pro that is subject to the treatment will react more
accurately to the change in the variable, given that, the previous golf ball
serves as a placebo in the study and after all the balls are hit, the distance
travelled by each set can be determined.
The correct option is therefore;
Yes, because the balls are randomly selected, the distance of the new ball can be compared to the distances of the original ball.Learn more experimental design here:

Answer:
6 and 28
Step-by-step explanation:
Question 8: Since the sum is atmost 16, the largest possible value of the number is available when the sum is 16. Then, we have 2x + 4 = 16, and that equals 2x = 12, which leads to x = 6.
Question 9. Since your bank value has to be above 525, and 814 dollars keep decreasing 10 each day, we know that it will stop at 534, because having 524 dollars will be below 525. Now, 814 - 534 = 280, and since you pay 10 every day, 280/18 = 28 days.
