Answer:
15x+25 ; 70
Step-by-step explanation:
Given that,
Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.
Here, $25 is constant and $15 increases as the number of hour increase. For x hours, the cost for Fernando to clean a pool is given by :
y = 15x+25
For 3 hours,
y = 15(3)+25
= 45 + 25
= 70
So, the required option is (c) " 15x+25 ; 70 ".
3:5 = 64cm
3x+5x= 64
8x=64
x=8
Therefore,
3x=8×3
=24
5x=8×5
=40
3x+5x=64cm
Y= -2x^3 is the answer
Hope this helps!
