5/7 = x/19.60
5/7x = 19.60
5/7(7/5)x = 19.60(7/5)
5/7(7/5)x = x/19.60(7/5)

B,C,E

Explanation:

got 100%

Answer 2

The second and 3dr

The third is the same as the second.But in the 3rd the x is multipied by 5/7 so when you multiplies by 7/5 you have the x isolated.Then you do the same thing on the other side,and multiply 19.60 by 7/5

so x=19.60 multiplied by 7 and then divided by 5

x=27.44 (amount spent on the store)
