Answer:
x = 17
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.
Answer:
12.42 + 3.6 = 16.02
1.81 + 19.25 = 21.06
-3.5 + 85.95 = 82.45
-75.23 + (-21.8) = -97.03
123.49 + (-6.02) = 117.47
Hope this helps.
Answer:
Technically, we do not know what x and y are, but there are some numbers that we can assume they stand for. For example, IF x = 10 and f = 1, that would mean the equation is basically 10 - 5 = 5. However, it could be multiple things, such as 20 - 15.
