- 8. Multiple Choice
One way to solve this equation
2/7 x + 3 = 8/7 x - 8
is to first
multiply both sides through by 2
multiply both sides through by 8
multiply both sides through by 7
add x to both sides
- 9. Multiple Choice
If you double a number and then add 12, you get 4/5 of the original number. Let x represent the original number.
Which equation represents this situation?
2x + 4/5 = 12
2x + 12 = 4/5 x
4/5 + 4x = 5
12x - 2 = 4/5 x
- 10. Multiple Choice
Carpet Cleaner A charges $28.95 plus $18 per room. Carpet Cleaner B charges $19.85 plus $32 per room. Which equation can be used to find the number of rooms for which the total cost of both carpet cleaners is the same?
28.95x + 18 = 19.85 + 32
28.95 + 32x = 19.85 + 18x
28.95 + 18x = 19.85 + 32x
(28.95 + 18)x = (19.85 + 32) x
