10 cm the ansswer could me 5cm half
Step-by-step explanation:
None of these really fit….. it would be
45/(6+3)
But none of your answers match so I’m not sure,,,,, sorry
Malia : y = 8.1x.....this tells me she makes 8.10 per hr worked
Bill : if he earned 144.90 for working 18 hrs.....144.90/18 = 8.05 per hr worked.
so Malia makes 5 cents more per hr worked.
Is that the answer ur looking for ?

Square 12.1, and subtract 121 from both sides.

Complete the subtraction on the right side.

This is the solution.
