A mowing company charges $840 plus $17 per hour. Another moving company charges $760 plus $22 per hour. How long is a job that costs the same no matter which company is used?

16 hours

Step-by-step explanation:

The two equations are:

840 + 17x

and

760 + 22x

with x being the amount of hours

840 + 17x = 760 + 22x  

-760

80 + 17x = 22x

-17x

80 = 5x

/5

16 = x

840 + 17(16) = 1,112

760 + 22(16) = 1,112

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
