Answer:

see below

Step-by-step explanation:

Let y = the total cleaning cost

Let x = the number of roots cleaned.

Therefore, if the cost is $22 per room, y = 22x

200 = 22x

Divide both sides by 22: 9 $\frac{2}{22}$ = x

Therefore, 9 rooms can be cleaned for $200

New equation: y = 22x + 40

200 = 22x + 40

Subtract 40 from each side: 160 = 22x

Divide both sides by 22: 7 $\frac{6}{22}$ = x

Therefore, 7 rooms can be cleaned for $200 if the carpet cleaners receive a $40 tip

The sum of two numbers is 9. Their difference is 15. Find the two numbers.

tankabanditka [31]

Answer:

x= 12 y= -3

Step-by-step explanation:

Rearrange.

x+y=9

x-y=15

Get x by itself, cancel out the y's and you'll get this:

2x=24

x= 12

Plug it in.

12+y=9

Get y.

y= -3

Check your work. I hope this helped.
