Q = d - 12
q = 28 - d
d - 12 = 28 - d
d + d = 28 + 12
2d = 40
d = 40/2
d = 20 <== 20 dimes
q = d - 12
q = 20 - 12
q = 8 <== 8 quarters

Hope This Helps :)
5.12 x 10*
(the * should be a little number 4 in the corner)
Answer:
21
Step-by-step explanation:
Since this is a parallelogram, the given angle measure must have equal measure because they are opposite angles:
2x - 4 = x + 17 transfer like terms to the same side of the equation
2x - x = 17 + 4 (notice the terms changes sign when transferring to the other side of the equation)
x = 21 is the answer we are looking for
