The answer is true because
(20) 3 = 10 (6)
60 = 60
You need to subtract the total number of pennies they have to the number of pennies they wrapped
Total: 592+128=720
Subtract total to the number of pennies wrapped
720-250=470
You can round 470 up to get 500 pennies that the girls had left
The answer is B
-9(x) = -117
Solve for "a number" (x). Isolate it. Note the equal sign. What you do to one side, you do to the other. Divide -9 from both sides.
-9x/-9 = -117/-9
x = -117/-9
x = 13
13 is your answer
hope this helps
