Sally has 13 coins in her pocket. nine of the coins are nickels, and the rest of the coins are dimes. how many of the coins are dimes? a. identify what is being asked. b. strategize (what variable will you use to represent the unknown? ) c. set up (write an equation) d. solve (find the solution) e. check (does your answer make sense? ) don't answer if you aren't going to answer all the questions!

A. How many dimes is there out of the 13 coins in his pocket.

b. D=Dimes

C. 9+d=13

D. 9+d=13

Subtract 9 from 13

13-9=4

d=4

9+4=13

YES

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
