Answer: -28
Step-by-step explanation: Since x is being divided by -4, to solve for x, multiply both sides of the equation by -4.
On the left side, the -4's will cancel
and on the right side, 7(-4) is -28.
So x = -28.

Answer: c
Step-by-step explanation:
<span>Since the number of quarters, dimes, and nickels is going to be the same for each, we can assign x as the quantity of each coin and place it by its monetary value:
.25x + .10x + .05x = 4.00
This then simplifies to:
.40x = 4.00
4 divided by .4 gives x a value of 10, so there would be 10 quarters, 10 dimes, and 10 nickels.</span>
