To answer the question above, let x the number of hours for the two jobs to cost equal. Harry's charge can be expressed as 70x + 130 and that of Lou is 80x + 40. Equating both,
70x + 130 = 80x + 40 ; x = 9
Thus, the job should take 9 hours for both charges to be equal.
First replace y with 15.
1/5x-10=30
Then just solve from there.
x=200
Answer:
90-24=76°
Step-by-step explanation:

Volume of a cone = <span>πr^2(h/3)
r=6
h=27
v = </span><span>π(6^2)27/3
v = </span><span>π (36)(9)
v=</span><span>π324 in. cubed
or
v=1,017.36 in. cubed </span>
7x+3+5x²
ax²+bx+c
5x²+7x+3
Hoped this helped!
