Accordinly to the details, i think that A could work.
If you simplify this expression you get 2x 2 -7x -2
2 angles are complementary if the sum of their measures is 90°.
For example if m(P) = 41° and m(Q)=49°, then P and Q are complementary.
Thus A and B are complementary means that m(A)=m(B)=90°:
(3x+5°) + (2x-15°) =90°
5x-10°=90°
5x=100°
x=20°
Thus
m(A)=3x+5°=3* 20°+5°=60°+5°=65°
m(B)=2x-15°=2*20°-15°=40°-15°=25°
Jason worked 20 hours at $5 per hour and 30 hours at $6 per hour.
20 hours at $5 per hour = 20 times 5
30 hours at $6 per hour = 30 times 6
He earned $280 in 50 hours. Divide:
Your answer is the last choice, $5.60
