Substitution is where you solve for one of the variables and then plug that in for the same variable in the other equation. Here, there is already an equation that is solved for a variable, \sf y=4x-11. So we can plug in '4x - 11' for 'y' in the other equation:

\sf 3x+5y=-9

\sf 3x+5(4x-11)=-9

Distribute 5 into the parenthesis(multiply it to every term in the parenthesis):

\boxed{\sf 3x+20x-55=-9}

Your answer is C.

Brandon has a jar of quarters and dimes with a total value of $7.05. The number of quarters is 3 less than twice the number of d
miv72 [106K]

Answer:

  • quarters: 23
  • dimes: 13

Step-by-step explanation:

Let d represent the number of dimes. Then the number of quarters is 2d-3 and the total value of the coins is ...

  0.10d + 0.25(2d-3) = 7.05

  0.60d -0.75 = 7.05 . . . . . . . simplify

  d = (7.05 +0.75)/0.60 = 13 . . . . add 0.75, divide by 0.60

  2d-3 = 2·13 -3 = 23

Brandon has 23 quarters and 13 dimes.
