Aconstruction contractor used the equation 11.72=(2.93)4 to calculate how much four boxes of nails would cost him. how much would 9 boxes of nails cost him?

  26.37

Step-by-step explanation:

Apparently, we're to substitute 9 for 4 and recompute:

  26.37 = (2.93)9

This assumes that the 4 in the expression is the number of boxes, and the (2.93) in the expression is the price per box. The product of those numbers is 11.72, apparently the total cost of 4 boxes of nails.

the correct answer is 45x

9×5=45 then add the x

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
