Answer:
2 inches per hour
Step-by-step explanation:
2 1/2 hours is equivalent to 150 minutes.
Set up a proportion; let x equal inches of rain
=
Cross multiply -> 150x=300
Divide both sides by 150 to get -> x=2
To find the answer make 25 equal to 6x+1
25=6x+1
25-1=24
24=6x
24/6=4
x=4
X=4
See the attachment.

4(2a+3) = 8a+ 12
This represents the distribution property because it multiplies everything in the parentheses. 4 X 2a = 8a 4X3=12
