Answer:
the equation used to determine the number of dimes in his pocket is an "algebraic equation" (3/4)x = 5.25
and the value of x = 7
Step-by-step explanation:
We are being told that:
Alex has 3 more quarters than dimes in his pocket, for a total of $5.25.
Let the value for the dimes in his pocket be x:
So he has 3 more quaters than x
We know that a quarter is 1/4
3 more quaters than x = (3/4) x
(3/4)x = 5.25
3x = 5.25 * 4
3x = 21
x = 21/3
x = 7
Thus, the equation used to determine the number of dimes in his pocket is an "algebraic equation" (3/4)x = 5.25
and the value of x = 7
