If im correct the answer would be 4, hope i could help out.
Answer:Each Y could equal 12
Step-by-step explanation:
You would divide each side of the equation y 3 to get y^2=144.
Next take the root of both sides to get y= ± 12
After that just separate the solutions and get 12.
(I hope this helps. I tried)
22.50 per hr for 4.5 hrs = 101.25...work pay
35 miles at 0.50 per mile = 0.50(35) = 17.50...travel pay
parts : 350 * 1.05 = 367.50...parts and taxes
total : 101.25 + 17.50 + 367.50 = 486.25
486.25 - 468.75 = 17.50.
answer is : The invoice is incorrect....he did not charge for travel <==
I thinks it’s the 2nd answer:)!
