Add 7 to both sides
3x + 12 = 7x
Subtract 3x
12 = 4x
Divide by 4
x = 3

Step-by-step explanation:
40+88+15=128+15=143
There are three rectangles that compose this shape. The first one has side lengths of 5 & 8 (l times w=a 5 times 8=40, area of the rectangle is 40). The second one has side lengths of 8&11 (8 times 11=88, area is 88). Final rectangles has side lengths of 16-(8+5) and 5 (16-13=3, 3 times 5=15, Area=15). All three of those rectangles added up is 143 as an area of the figure.
U times 2 and seven and divide that by 3 and then dive 3 by 2 and that should leave u with three numbers.
514 and 1.5 times those together and there u go
105
This problem is basically asking what 960x3.25 is, since 6 hours is one fourth of a day.
960x3.25=3120 watt-hours.
3120 watt-hours is your answer.
