Answer:
yes
Step-by-step explanation:
0.25q + 0.1d = 4.95
d = 3q
0.25q + 0.1(3q) = 4.95
0.25q + 0.3q = 4.95
<u>0.55q</u> = <u>4.95</u>
0.55 0.55
q = 9
0.25(9) + 0.1d = 4.95
2.25 + 0.1d = 4.95
<u>- 2.25 - 2.25</u>
<u>0.1d</u> = <u>2.7</u>
0.1 0.1
d = 27
For x, the answer is x >= -(3 - y)/2, for y it's y <= 2x -3.
