Alysha has 13 nickel rolls.
Let x be the number of dime rolls and y be the number of nickel rolls.
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
Each dime roll has 50 dimes, then x dime rolls are worth 50×10×x=500x cents or $5x.
Each nickel roll has 40 nickels, and then y nickel rolls are worth 40×5×y=200y cents or $2y.
A. The total value of Alysha's rolls is 500x+200y cents or $(5x+2y).
If the total value of the coins is $71 and she has 9 rolls of dimes, then x = 9 and 5×9+2y=71.
⇒45+2y=71
⇒2y=71-45
⇒2y=26
⇒y=13
Therefore, Alysha has 13 nickel rolls.
