Answer:
x=10
Step-by-step explanation:
3(4x-12) = 84
Divide each side by 3
3/3(4x-12) = 84/3
4x-12 =28
Add 12 to each side
4x-12+12 = 28+12
4x= 40
Divide each side by 4
4x/4 = 40/4
x = 10
Answer:
C = 210cm^3
Step-by-step explanation:
We can get an estamate when we use the equation L x H x W = x/2
This shows 8 x 8 x 7, then divide by 2 = 224cm^3
The reason it is slightly less could be the facts the teachers want you to remember this one.
For right side prism the equation is (1/2)b x h x H
which means;
The volume of a triangular prism can be found by multiplying the base times the height. Both of the pictures of the Triangular prisms below illustrate the same formula. The formula, in general, is the area of the base (the red triangle in the picture on the right) times the height,h.
We use the side and base that surrounds the right side as (1/2)base and as side to find area then use the H as the height being the 7.
Since you haven't identified this figure, I'm going to assume that it's a rectangle.
The Perimeter of a rectangle of length L and width W is P = 2L + 2W.
Here you are given the Perimeter and the length, and are to find the width, W.
Solving the above equation for W, we get P - 2L = 2W.
Dividing by 2 (to isolate that W), we get
P
-- - L = W
2
Substitute P= 6 yds and L = 6 feet (or 2 yds), find W (in yards).
Answer: $817.35
Step-by-step explanation:
150x4 = 600
600+217.35 = 817.35
8 ÷ 11 = 0.72727272...
Therefore, decimal '72' is repeating
