Answer:
x = -7/9
Step-by-step explanation:
The usual recommendation is to clear fractions first. Here, you can do that by multiplying both sides of the equation by 6.
6(-1/2(3x -4) +3x) = 6(5/6)
-9x +12 +18x = 5 . . . . . . . . . simplify
9x = -7 . . . . . . . . . . . . . . . . . subtract 12
x = -7/9 . . . . . .divide by 9

Another way to do this is to eliminate parentheses first.
-3/2x +2 +3x = 5/6
3/2x = -7/6 . . . . . . . . . collect terms, subtract 2
x = (-7/6)(2/3) = -7/9 . . . . multiply by 2/3
Answer:
8 kilometers in one hour
Step-by-step explanation:
4:30/4
30 
by 4
7.5
4 divided by 4
1
7.5 minutes to 1 kilometer
since there are 60 minutes in a hour
60/7.5 = 8
8 x 1 = 8
129 divided by 12 is 10.75. hope this helps.
The answer would be 0.3 * 15 = 4.5
Divide the length of the wall by 2 to find the center of the wall:14/2 = 7 feet
The center of the painting is 2/2 = 1 foot.
The edge of the wall would be the center of the wall minus the center of the painting:
7 - 1 = 6 feet.
There should be 6 feet on each side of the painting.
