25c(quarters) x 12 = $3.00
If theres 28 coins, and 12 are quarters, then that means theres 16 coins left to use for dimes.
10c(dimes) x 16 = $1.60
$3.00 + $1.60 = $4.60
Therefore, there are 12 quarters and 16 dimes.
Hope this helps! Feel free to ask any questions.

The reciprocal of 7 is 1 divided by 7.
Other examples;-
1/4: the reciprocal (flipping it) = 4/1 = 4.
3/4: reciprocal is 4/3.
Domain is the values of y.
Plug the x values in the equation to find the corresponding y values:
when x=0, y=3
when x=2, y=-1
when x=-6, y=15
so the answer is D
Answer: One solution
Step-by-step explanation:
3(x-2) + 7x = 1/2 (6x - 2)
3x - 6 + 7x = 1/2(6x) + 1/2(-2)
10x - 6 = 3x - 1
7x - 6 = -1
7x = 5
x = 5/7

X-12(8-x)=x+3(4-x)-x =x 27/4
x-1/2(8-x)=x+3(4-x)-x =x 32/9
