Answer:
7.C
9.C
10.6x+5=15
Explanation:
7 is trying to trick you. You have to divide 43.20 by 5 instead of 4. They split the tickets, but they gave some to her too.
For 9, add 2 to both sides. You will get 4x= 16. Then divide both sides by 4. You will get 4 as your answer.
For 10, on the left side there are 6 boxes with the letter x on it. This means 6x. There is also 5 circles with the number 1 on it. Then you will have 6x+5. Then the right side. There are 15 1’s total. Add them all up and you get 6x+5=15. In this question, you don’t have to answer it.
Man I wish I had your homework.
