Answer: D. 10
Step-by-step explanation:
4/3 (x + 8) = 24
Multiply both sides by 3/4....
x + 8 = 18
x = 10
Answer:
The choices were typed wrong, but we can find the inverse of each option.
For function 
the inverse is the same function 
, because an inverse of a function is where their composition gives the independent variable as unique result.
If we do that with each function, we have:
; where and , we have
So they are inverse.
For 
its inverse would be 
, because
For 
, its inverse is 
, because
For 
, its inverse is 
, because
There you have all inverses. Basically, if their composition results in 
, that means they are inverse.
Answer:
2/3 hour per mile.
Step-by-step explanation:
Hours per mile
= hours taken / miles walked
= 4/6 = 2/3 hour per mile.
Might Want to draw this and Its very long but Hope it helped :)
Answer:
The sides are all of the same length - let's say a. The angles are all the same too, and since the angles must add up to 180∘, we conclude that the three angles in the equilateral triangle are equal to 180∘/3=60∘.
Now we do something sneaky. We draw a line all the way down from the top vertex of the triangle to the midpoint of the bottom line.
This new line cuts our equilateral triangle in half. What are the angles in one half?
The angle at the bottom is 90∘.
One of the angles is the same as one of the angles in the original equilateral triangle, so it is 60∘.
So the third angle must be 180∘−90∘−60∘=30∘.
Now the hypotenuse of this new triangle is a, the side length of the equilateral triangle. And the length of the shortest side is a/2, since the line we drew cut the bottom line in half.
