4X + 8 9X+3 (this is the equation, nothing to explain in this step)

4x + 5 = 9x (you combine or subtract the like terms, 8 - 3 = 5)

5 = 5x (you do 9x - 4x = 5x, subtracting the like terms)

1 = X (your answer after dividing 5 from both sides)

The surface area of a rectangular prism is 32 square inches. The volume of the prism is 12 cubic inches. The sum of all edge len
Goryan [66]

Answer:

36 cubic inches.

Step-by-step explanation:

Let the length, width and height of the rectangular prism are a, b, c respectively.

So, surface area, 2(ab + bc + ca) = 32 {Given} ............ (1)

Volume, abc = 12 {Given} ............ (2)

And, the sum of all the edges, 4(a + b + c) = 28 {Given} .......... (3)

Now, if the length width and height are increased by 1 inch, then the volume of the prism will be = (a + 1)(b + 1)(c + 1)

= abc + (ab + bc + ca) + (a + b + c) + 1

= 12 + 16 + 7 + 1 {From equations (1), (2) and (3)}

= 36 cubic inches. (Answer)

Three brothers share 2 sandwiches equally how much of a sandwich does each brother get?
Valentin [98]
<span><u><em>Answer:</em></u>
Each brother gets </span>\frac{2}{3}<span> of a sandwich

<u><em>Explanation:</em></u>
We know that the total number of sandwiches is 2 and that the number of brothers is 3.

Since we are given that the sandwiches will be divided equally among the three brothers, this means that each will get an equal share.

Therefore, to get the share of each, we will simply <u>divide the number of sandwiches by the number of brother</u>s as follows:
each one will get = </span>\frac{# sandwiches}{# brothers} = \frac{2}{3}<span> of a sandwich

Hope this helps :)</span>
