Answer:
9/a
Step-by-step explanation:
8/a - 6/a + 7/a
Since the denominators are the same, we can add the numerators
8-6+7 =9
Then put it over the common denominator a
9/a
8+2x is the answer. The rest of these characters is for the >20 rule
The answer would be 15h+25 because h isthe variable representing hours and they charge $15 for every hour. And also, the plus 25 is for the setup fee.
