Step-by-step explanation:

Answer 2

Answer:

The value is $10.21, and it shows the change Pablo received.

Step-by-step explanation:

1. Identify the operation in the equation.

2.then use inverse operations. SUBTRACTION = ADDITION

ADDITION = SUBTRACTION

DIVISON = MULTIPLICATION

MULTIPLICATION = DIVISION.

if the equation is being add, subtract. for example

subtract 9.79 to both sides. subtract or add the number next to x to make x isolated. when we had 9.79 to bot sides, we get 10.21.

so in this case, 10.21 is your answer.

hope this helps.
