to solve this, you need to set up an equation to solve for <em>x, </em>the number of square meters waxed in an hour:

you can use cross multiplication to solve for x:


so jessica can wax 100/3 square meters per hour. you can convert this to decimal form (which would be 33.3 repeating) or you can leave it in fraction form.
Answer:
She wrote a 4 instead of a 3.
There are only 3 numbers that are greater than 7. They are 8, 9, and 10. Mariah must have include 7 in her list. That is how she got 4 instead of 3.
Answer:
its 10 + 4x and 10 + x+x+x+x
Answer:
Step-by-step explanation:
<u>Use formula:</u>
<u>Given</u>
- P = $700
- r = 4% = 0.04
- t = 7 years
<u>Find the amount:</u>
- A = 700*e^(0.04*7) = 926.19
Answer:
slope is 9
Step-by-step explanation:
use the formula y=mx+b wherein m is the slope and b is the y-intercept
to solve for m, use formula (y2-y1)/(x2-x1):
=
(you add 5 and 9 together because negative + negative is positive)
126/14 = 9
