X can be anything bigger than 7, and numbers go on forever so infinite
We know that
<span>4 1/2 gallons-------> (4+2+1)/2-----> 9/2 gallons
</span>
1 <span> wall in the house will need --------> 3/4 of a gallon of paint
</span> X wall-----------------------------------> 9/2 gallons
x=(9/2)/(3/4)----> 9*4/2*3-----> 36/6----> 6 walls
the answer is
6 walls
The value of x that will make the proportion true is
C. 7
