Fill in the blank to write a one variable, one-step equation for the following information: Matthew has twice as many quarters as dimes. Matthew has 20 dimes.(1 point)
q=20
To write a one variable, one-step equation for this information, we can use the equation:
q = 2d
Where q represents the number of quarters and d represents the number of dimes. Since we know that Matthew has 20 dimes, we can substitute d = 20 into the equation:
q = 2(20)
q = 40
Therefore, the equation is q = 40.
