Dimes = X
Nickle = X + 8
Quarters = 57 - x - (x + 8) = 49 - 2X

Trick -
Total were 57
Nickel 8 more than something it means without those 8 we are left with 49 so answer has to be in the format 49 - Something. Only one option even without solving.

Dimes = x

Nickels = x+8

Quarters = y

x+x+8+y = 57

y= 49-2x

Given: x = the number of dimes

The purse contains 8 more nickels than dimes
So, x + 8 = the number of nickels


The purse contains 57 coins
In other words: (number of nickels) + (number of dimes) + (number of quarters) = 57
Substitute to get: (x + 8) + x + (number of quarters) = 57
Simplify: 2x + 8 + (number of quarters) = 57


Which of the following gives the number of quarters the purse contains in terms of x ?
Take: 2x + 8 + (number of quarters) = 57
Subtract 8 from both sides of the equation to get: 2x + (number of quarters) = 49
Subtract 2x from both sides to get: number of quarters = 49 - 2x

Answer: D

Brent

Dimes \(= x\)

Nickle \(= x + 8\)

Quarters \(= 57 - x - (x + 8)\)

\(= 49 - 2x\)

The answer is \(D\)
