Answer:
a and b are equivalent.
c, d and e are not equivalent.
So, 2 equivalent expression for c and are,
c.
( i ) 2 ( x + 2 )
( ii ) ( 4x + 8 ) / 2
d.
( i ) 3x + 16
( ii ) ( 6x + 32 ) / 2
Step-by-step explanation:
a.
2 ( x + 4 )
= 2 ( x ) + 2 ( 4 )
= 2x + 8
b.
8 + 2x can also be written as 2x + 8.
d.
3 ( x + 4 ) + ( 4 + x )
= 3 ( x ) + 3 ( 4 ) + 4 + x
= 3x + 12 + 4
= 3x + 16

1/2(x - 4) = 5
Thank you!
Answer:
x = 14
Step-by-step explanation:
1/2(x - 4) = 5 - Given
1/2x - (1/2 * 4) = 5 - Distribute
1/2x - 2 = 5 - Multiply 1/2 by 4
1/2x = 7 - Add 2 to both sides of the equation
x = 14 - Divide both sides of the equal by 1/2

The base angles of an isosceles triangle are the angles formed by the base and one leg of the triangle. The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent.Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.[tex]x = \sqrt{ {7}^{2} + {7}^{2} } \\ x= \sqrt{49 + 49} \\ x = \sqrt{98} \\ x= \sqrt{49 \times 2} \\ \boxed{x= 7 \sqrt{2} }[/tex]

yard? Explain.
HERE IS WHAT I GOT SO FAR PKEASEEEE. HELP I AM LOST jsjsjdndjdj
Answer:
16
Step-by-step explanation:
8/12 ÷ 1/12 = 8/12×24/1=192/12=16
The required number of books that can be fitted to the 8/12 yard long bookshelf is 16 books.
Given that,
A small bookshelf is 8/12 yards long. how many books can fit on the shelf if the width of each book is 1/24 yard is to be determined.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
here,
The total length of the shelf = 8 / 12 yard
Width of a book = 1 / 24 yard
So the total number of books that can be accumulated on the shelf will be the ratio of the total length of the shelf to the width of a book. So,
Total books = 8 / 12 / {1 / 24]
= 8 * 24 / 12
= 16
Thus, the required number of books that can be fitted to the 8/12 yard long bookshelf is 16 books.

Two minor league baseball players got a total of 360 hits. Washington had 14 more hits than Sanchez. Find the number of hits for each player.
Question content area bottom
Part 1
Washington had enter your response here
hits. Sanchez had enter your response here
hits.
Answer:
denote the number of hits that sanchez had with since washington had 18 more hits than sanchez we can say that washington had + 18 hits.
since the total number of hits is 308 we can write
+ ( + 18) = 308.
This is an equation for finding .
2 + 18 = 308
2 = 290
= 145.
so sanchez had 145 hits.
to find the number of hits by washington add 18:
+ 18 = 145 + 18 = 163.
Answer: sanchez had 145 hits and washington had 163 hits.

ty !
Answer:
Step-by-step explanation
There are many ways to prove this identity. But, I will use the simplest one. If you have a right triangle, the length of the horizontal side is x, the length of the vertical side is y, and the hypotenuse is r. So, the relation between x and r can be written in cosine form:
[tex]\cos\theta=\frac{x}{r}[/tex]
The relation between y and r can be written in sine form:
[tex]\sin\theta=\frac{y}{r}[/tex]
Pythagoras told you that for the right triangle [tex]x^{2}+y^{2}=r^{2}[/tex] should be satisfied. Substitute x and y from the cosine and sine form:
[tex](r\cos\theta)^{2}+(r\sin\theta)^{2}=r^{2}[/tex]
[tex]r^{2}\cos^{2}\theta+r^{2}\sin^{2}\theta =r^{2}[/tex]
the square of r will cancel out, and you can get your identity:
[tex]\cos^{2}\theta+\sin^{2}\theta=1[/tex]

Andres works at a job that pays him 12.50 an hour.Andres works 30 hours a week.How much does he make each month after 30% of california state income tax is taken out?
Answer:
he makes $112.50
Step-by-step explanation:
first you have to find out how much he makes before tax is taken out. all you do is multiply 12.50 by 30, which gives you $375.00. then, you can either put in the calculator 30%375 or 0.3×375(both are the same thing) and you should get $112.50

2. What is the equation of the line in point-slope form? Use the point on the graph.
9514 1404 393
Answer:
y -1 = 1/2(x +2)
Step-by-step explanation:
The line has a rise of 1 grid unit for each 2 that it goes to the right. Its slope is then m = rise/run = 1/2. The given point appears to be (-2, 1).
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
For the given slope and point, this is ...
y -1 = 1/2(x +2)

If 81 is added to a number, the result is 39 less than three times the number. Find the number.
Answer:
60
Step-by-step explanation:
The number is represented as x.
81 is added to a number is
81 + x
39 less than three times the number
3x - 39
So
81 + x = 3x - 39
Solve for x.
81 + x = 3x - 39 Add 39 to each side so 39 cancels on the right.
81 + x + 39 = 3x - 39 + 39
81 + x + 39 = 3x
81 + 39 + x = 3x
120 + x = 3x Subtract x from each side.
120 + x - x = 3x - x
120 = 3x - x
120 = 2x Divide each side by 2
120/2 = 2x/2
120/2 = x
60 = x

at a 911 call center, calls come in at an average rate of one call every two minutes. assume that the time that elapses from one call to the next has the exponential distribution. Find the probability after a call is received, it takes more than 3 minutes for the next call to occur.
Using the exponential distribution, it is found that there is a 0.2231 = 22.31% probability after a call is received, it takes more than 3 minutes for the next call to occur.
What is the exponential distribution?The exponential probability distribution, with mean m, is described by the following equation:
[tex]f(x) = \mu e^{-\mu x}[/tex]
In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.
The probability of finding a value higher than x is:
[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]
In this problem, the mean is of two minutes, hence the decay parameter is given by:
[tex]\mu = \frac{1}{2} = 0.5[/tex]
The probability that it takes more than 3 minutes for the next call to occur is given by:
[tex]P(X > 3) = e^{-0.5 \times 3} = 0.2231[/tex]
0.2231 = 22.31% probability after a call is received, it takes more than 3 minutes for the next call to occur.

Answer:
y - 4 = -2(x - 5)
Step-by-step explanation:
point slope form is y-y1 = m(x-x1)
the original equation is given in slope intercept form y = mx + b
Parallel lines have equal slopes so from the given equation y = -2x-3
the slope m = -2.
Use the given point (5,4) as (x1, y1).
y - 4 = -2(x - 5)
Answer:
[tex]\displaystyle y - 4 = -2(x - 5)[/tex]
Step-by-step explanation:
Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so −2 remains as is as you proceed with plugging the information into the Point-Slope Formula:
