Paid same amount is important.
5 hours each one, and 4 babysitters
5*4 is 20
And if there's 170 dollars she paid in total, then each babysitter earned 170/20 per hour, which is 8.5 dollars per hour
Just set the equations equal to each other
(1,-4)
Answer:
Rational
Step-by-step explanation:
Because it gives whole number which is 11
The answer is 8 because when you replace x by 8 it equals 24
The other person did not explain so I will:
(68+79+74)= 221/3 =73.7
80 x 4 = 320
320-221 = 99
He must get 99 on his 4th test.
Thanks
