3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x
30 + 12 = 42, 12 + 12 = 24, I am not completely sure on the answer as the two subtractions can be taken in either order, either resulting in: 42 - 24 + 18, 18 - 12 = 6, or 24 - 12 = 12, 42 - 12 = 30.
If: k/2 + 9 = 30 Then: k = 42
42/30 = 1.4 = 140 %
42-3x10+2 first you do multiplycation42-30+2 now you do subtraction12+2 lastly, you subtract14 your answer is 14
3x + 12 = 42 3x = 30 x = 10
(5+7-42)(24-2+3) = (12-42)(22+3) = (-30)(25) = -750
23/42 + 1/6 = 23/42 + 7/42 = 30/42 = 5/7
3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x
30 + 12 = 42, 12 + 12 = 24, I am not completely sure on the answer as the two subtractions can be taken in either order, either resulting in: 42 - 24 + 18, 18 - 12 = 6, or 24 - 12 = 12, 42 - 12 = 30.
-36 + 6 = -30
If: k/2 + 9 = 30 Then: k = 42
42/30 = 1.4 = 140 %
You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.The answer is 42.
42% of 30= 42% * 30= 0.42 * 30= 12.6
30% of 42= 30% * 42= 0.3 * 42= 12.6
42 inches = 3-1/2 feet
