Kesha spent a total of $9.60 on new shoelaces. each pair cost $1.20. how many pairs of shoelaces did she buy

8

Step-by-step explanation: She bought 8 shoelaces because 9.60 divided by 1.20 is 8

Step-by-step explanation:

If the total is 9.60 then it would be 1.20x = 9.60 where x = pair of shoelaces.

To work out the problem you have to divide 1.20 from both sides.

1.20x/1.20 = x

9.60/1.20 = 8

Therefore, x = 8; Kesha bought 8 pairs of shoelaces.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
