Answer:
x=5
Step-by-step explanation:
four times two x gives you 8x. 4 times 4 is 16. Subtract 16 from both sides you get 40. divide 8x by 8 and the eights cancel out. Divide 40 by 8 and you get 5
Since bc = 6, that makes db = 3 and cd = 3rad3
cd (2) = ac. so ac = 6rad3
so to get ad, you square ac which = 108, square cd which = 3rad3 which equals 27. 108 - 27 = 81. the sqaure root of 81 is 9. ad = 9
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.
