Answer:

x=-5

Step-by-step explanation:

Add 22x to both sides: -8x+100=140

Subtract 100 from both sides: -8x=40

Divide both sides by -8: x=-5

So the answer is x=-5

Micah rows his boat on a river 4.48 miles downstream, with the current, in 0.32 hours. He rows back upstream the same distance,
Molodets [167]
Let the speed of the current be y and the speed of Micah's sailing speed be x. Then 4.48/(x + y) = 0.32
4.48/(x - y) = 0.56

0.32x + 0.32y = 4.48 . . . (1)
0.56x - 0.56y = 4.48 . . . (2)
(1) x 7 => 2.24x + 2.24y = 31.36 . . . (3)
(2) x 4 => 2.24x - 2.24y = 17.92 . . . (4)
(3) - (4) => 4.48y = 13.44
y = 3
From (1), 0.32x + 0.32(3) = 4.48
0.32x = 4.48 - 0.96 = 3.52
x = 3.52/0.32 = 11

Therefore, the speed of the current is 3 miles per hour.

Juliette [100K]
It depends on how the colors are located.. but you solve by twisting the rubik's cube over and over again and trying to get 3 rows of the same together on one side of the rubrics cube.that way some colors that u did not solve yet . might be matched up a little. and so the goal is to try and get all 6 sides of the rubric cube have the same color :)
