Answer: x = 4

Step-by-step explanation:

To solve this problem, make use of the fact that you may add anything to an equation, as long as you do it to both sides.

Simply add 4x to both sides to get:

13 = 1 + 3x

Then simply add -1 to both sides to get:

12 = 3x

Then, divide both sides by 3 to get:

4 = x

Hope it helps :) and let me know if you want me to elaborate.

Naily [24]

The height of the prism is $2.25 \ in$

Explanation:

It is given that the area of the cross section of the rectangular prism is 45 square inches.

Length of the rectangular prism is $5 \ in$

Width of the rectangular prism is $5 \ in$

To determine the height of the prism, let us substitute these values in the formula $SA=(2l+2w)h$ , we get,

$45=(2(5)+2(5))h$

Multiplying the terms within the bracket, we get,

$45=(10+10)h$

Adding the terms within the bracket, we have,

$45=20h$

Dividing both sides by 20, we get,

$2.25=h$

Thus, the height of the rectangular prism is $2.25 \ in$

U equals vw plus z solve for v

padilas [110]

Subtract z from the right side so that it becomes... u - z = vw

Then all you do is divide the right side of the equation(or equals sign) by w because your goal is to get whatever you're solving for by itself.

Your answer, then, is... u-z/w = v
