Answer:
Vertical angles
Step-by-step explanation:
W+D=659
W=D-91
---------------------------
(D-91)+D=659
D-91+D=659
2D=750
D=750/2=375
------------------------------
W+375=659
W=284
------------------------------
So the dryer had cost $375 and the washer had cost $284.
Janet = 1/3
Gary = 1/2
(1/3) + (1/2) = 5/6
Let x = time they both can do the job together
(1/2) + (5/6)x = 1
Solve for x to find your answer.
Answer:
x=0
Step-by-step explanation:
10(x-2)=-20
10x-20=-20
add 20 on both sides.
10x=0
10 times 0 =0
x=0
