Answer:
x=a+b
Step-by-step explanation:
Just move a to the other side (by adding it)
<span>it divides two sides of a triangle equally. The midpoint of a side divides the side into two equal segments.</span>
Answer: 
Step-by-step explanation:
Pythagorean theorem:
, where a and b are the legs and c is the hypotenuse.
We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.


Since we don't know what
is, we're going to isolate it by subtracting 81 on both sides

We have to square root both sides in order to find out b (or x in the problem).

When you put this on a calculator it would result in
which is the answer d in the problem.
Answer:
C=5h+3 when h=5
C=28
Step-by-step explanation:
She charges $5 per hour (5h)
and a flat fee of $3 (+3).
Replace the h (the number of hours babysitting) with 5 (the amount of hours you want to find for).
Then you multiple 5 and 5, then add 3.
Which gives you an answer of $28.
Hope this helped!
