Dean is painting a fence. If 3/4 gallon of paint can cover 1/8 of the fence, how many gallons will he need to paint the whole fence?

He will need 6 gallons to paint the whole fence

Step-by-step explanation:

To know the number of gallons that will be needed to paint the whole fences, we will follow the step below;

let x be the number of gallons that he will need to paint the whole fence

We can use proportion to solve the problem

3/4 gallon =    1/8  fence

 x gallon    = 1  fence

cross-multiply

3/4  ×  1  =   1/8   ×    x

              =  

CROSS-MULTIPLY

4 × x = 3 × 8

4x  =  24

divide both-side of the equation by 4

4x/4  =  24/4

x =6

Therefore,he will need 6 gallons to paint the whole fence

answer: a clock

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
