Diego scored 100 points less than Maria on a game. Maria scored 850 points on the game. Which expression shows the number of points Diego scored?
A. 850+100
B. 850 -100
C. 85+100
D. 85-100
Answer:
B. 850-100
Step-by-step explanation:
Less than means you should take away (subtract). Since Diego scored less than Maria you are taking the number of points Diego got away from Marias points. So it would be 850 take-away 100, or 850-100.

70.5 rounded to the nearest whole number
Answer:
71
Step-by-step explanation:
the fractional part is 5 and 5 is 5 or above. Therefore, we add 1 to the integer part and remove the fractional part to get the answer Therefore, we add 1 to the integer part and remove the fractional part to get 70.5 rounded to the nearest whole number which is 71
Given (x - 1)2 = 50, select the values of x.
x = -49
X = 51
x= 1+5VE
x-1-52
Answer:
x = 26
Step-by-step explanation:
(x - 1) 2 = 50
or, 2x - 2 = 50
or, 2x = 50+2
or, 2x = 52
or, x = 52/2
or, x = 26
hence, x = 26
Dylan is playing with a see-saw on the playground. He puts a piece of tape at specific distances from the center of the see-saw so that there ratio of the distance between the center and the tape and the distance between the center and the right end is always a common fraction. Dylan then records the relationship between the height of the tape and the height of the left end of the see-saw, relative to a neutral position.
Use the pattern you observe in the table below to correctly complete Dylan’s conjectures.

height of left end

If the tape is placed at 13 of the distance between the center and right end, when the left end is at a height of 18 centimeters, relative to a neutral position, the tape will be at a height of
centimeters, relative to a neutral position.
If the tape is placed at 14 of the distance between the center and right end of the see-saw, then the height of the left end will be
times the height of the tape, relative to a neutral position.

Step-by-step explanation:
A runner runs at an average speed of 5 m/s for 50 seconds.
How far did the runner run in metres?
Answer:
He has ran 250 metres.
Step-by-step explanation:
Since he runs 5 meters per second, you would obviously multiply 50 times 5, which is 250.
Answer:
250 meters
If you do 5 x 50 you will get how far the runner ran because I mean that's how averages work, I really hope this helped!
The sum of interior angles in a triangle are 180 degrees. Angle B and C are congruent. Angle B is twenty less than angle A. Write and solve a system of equations using substitution. Write and solve a system to determine the measure of angles A, B, and C.
Answer:
[tex]A = \frac{220}{3}[/tex]
[tex]B = \frac{160}{3}[/tex]
[tex]C = \frac{160}{3}[/tex]
Step-by-step explanation:
Given
[tex]A + B + C = 180[/tex]
[tex]B = C[/tex]
[tex]B = A- 20[/tex]
Required
Solve for A, B and C
The equation binding A, B and C have been written out (above)
Substitute C for B in [tex]A + B + C = 180[/tex]
[tex]A + B + B = 180[/tex]
[tex]A + 2B = 180[/tex]
Substitute A - 20 for B
[tex]A + 2(A - 20) = 180[/tex]
[tex]A + 2A - 40 = 180[/tex]
[tex]3A - 40 = 180[/tex]
Solve for 3A
[tex]3A = 180 + 40[/tex]
[tex]3A = 220[/tex]
[tex]A = \frac{220}{3}[/tex]
Solve for B in [tex]B = A- 20[/tex]
[tex]B = \frac{220}{3} - 20[/tex]
[tex]B = \frac{220 - 60}{3}[/tex]
[tex]B = \frac{160}{3}[/tex]
Recall that [tex]B = C[/tex]
[tex]C = \frac{160}{3}[/tex]

Step-by-step explanation:
3a+ 6 = 15, 3a = 9, a+ 2= 5, 1/3a =1
are any of these equation equivalent to one another if so, which ones? Explain tou reason
Given parameters:
Find if any of the equations are the equivalent;
3a+ 6 = 15
3a = 9
a+ 2= 5
[tex]\frac{1}{3a}[/tex] =1
To find which of the equations are equivalent to one another, let us solve them first. The ones with the same solution are definitely equivalent.
(i) 3a+ 6 = 15
3a = 15 - 6
3a = 9
a = 3
(II) 3a = 9
a = 3
(III) a+ 2= 5
a = 5-2
a = 3
(IV) [tex]\frac{1}{3a}[/tex] =1
1 = 3a
a = [tex]\frac{1}{3}[/tex]
We clearly see that the first three equations are equivalent.

At present, the highest peak of the Appalachian Mountains is 6,684 feet. Millions of years ago, before weathering and erosion had occurred, the highest peak was about 30,000 feet. What is the difference between the highest peak millions of years ago and the highest peak today? Explain how you know your answer is reasonable. Enter the correct numbers in the boxes to show the answer and to complete the explanation.
Answer:
23316ftStep-by-step explanation:
in this problem, we are expected to solve for the change in height of the Appalachian Mountains
given that
the initial height was = 30,000 feet.
the current height is=6,684 feet.
Due to erosion the change/difference in height is give as
change/difference=30000 -6684
change/difference=23316ft
this means that for millions of years ago 23316ft of Appalachian Mountains have been eroded
Write and solve an equation to answer the following question. The Smith family rented a recreational vehicle for a seven-day vacation. The cost to rent the recreational vehicle was $560 plus $0.50 per mile. How many miles were driven if the total cost was $1350?
a. 790 mi
b. 1580 mi
c. 395 mi
d. 3820 mi
Answer:
1580 miles
Step-by-step explanation:
We can represent the total cost for the rental with the equation d=560+0.5m where d is the cost and m is the miles driven. We know this equation works as 560 is the fixed cost, and it costs $0.5 per mile, and in math, "per" means multiplication.
Now we can solve for m as we know that d=1350 in this case.
Solving we get:
1350=560+0.5m
790=0.5m
1580=m
Thus, they drove 1580 miles.

Scott is making a dip that has 3 5 of a teaspoon of garlic for every 1 2 of a teaspoon of hot sauce. What is the unit rate of garlic to hot sauce in the dip? 1 3 5 teaspoons of garlic per teaspoon of hot sauce 5 6 teaspoon of garlic per teaspoon of hot sauce 1 1 5 teaspoons of garlic per teaspoon of hot sauce 2 3 teaspoon of garlic per teaspoon of hot sauce
Answer:
1/ 1 5 teaspoons of garlic per teaspoon of hot sauce
Step-by-step explanation:
Scott is making a dip that has 3 /5 of a teaspoon of garlic for every 1 /2 of a teaspoon of hot sauce.
3/5 teaspoon of garlic = 1/2 teaspoon of hot sauce
1/2 teaspoon of hot sauce = 3/5 teaspoon of garlic
1 teaspoon of hot sauce =
= 1 × 3/5 ÷ 1/2
= 3/5 ÷ 1/2
= 3/5 × 2/1
= 6/5
= 1 1/5 teaspoon of garlic.
Therefore, the unit rate of garlic to hot sauce in the dip is:
1/ 1 5 teaspoons of garlic per teaspoon of hot sauce

The value of function f(x) = |x-3| at x=3:
f(3) = 0
Given,
f(x) = |x-3|
Now,
Here the function f(x) is modulus function . Thus the values coming out of the function will be positive .
So,
f(x) = |x-3|
Now we have to substitute the value of x in the function.
f(3) = |3 - 3|
f(3) = |0|
f(3) = 0
Thus the value of function at x = 3 is 0 .
