Hello there!
We reverse the whole problem. 12 - 4 = 8.
x = 8.
8 + 4 = 12.
x = 8
If F(3) then 3=x. So all you would do is substitute 3 in for x
Answer:
5/12.5 = 8/p
Step-by-step explanation:
There is 5 pictures in 12.5 hours
How many can he paint in 8 hours
8=HOURS
P=AMOUNT
Ok you solve the first one, so
5m = 36.25 <em>divide by 5 on both sides</em>
m= 7.25
then you need 7m. m = 7.25 so put that in there and solve to get
D) 50.75
