Dylan has a bank that sorts coins as they are dropped in. The panel on the front shows that there is a value of $17.55 inside of the bank. Dylan only collects dimes and quarters. If the number of quarters he has is nine less than twice the amount of dimes, write an equation that can be used to model this equation.

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
