Answer:
He will need 6 gallons of painting to paint the whole fence.
Step-by-step explanation:
Since 3/4 gallon of paint covered 1/8 of the fence, we have to multiply 3/4 by 8 in order to find the number of gallons that will paint the whole fence (because 8 x 1/8 = 1)
x
=
= 6
Hope this helps!
I basically solved for x first.
42+43x+1=180
X=3.2 rounded
Next plug in the value of x into the EDC equation
43(3.2)+1=138.6
Then add it to the measure of EDN
138.6+42= 180.6
So the answer is measure of NDC= 138.6
