Answer: x=15
Step-by-step explanation:
Question 1:Multiply both sides of the proportion by 35.
You get.
7(x-1) = 4x+2
7x-7 = 4x+2
Now, add both sides by 7 and subtract both sides by 4x
3x = 9
Divide both sides by 3
x=3
Question 2:Multiply both the numerator and the denominator of

by 3.
We want to multiply it by 3 so that the +1 and +3 become +3 and +9. +3 and +9 have a difference of 6, just like 15 and 21, which is what we want.

Set the numerator equal to the numerator and the denominator equal to the denominator.
3x+3 = 15
3x+9 = 21
If you solve both of these, you get x=4 for both.
That's your answer.
Hope this helps! :)

8748 in³ is the volume of the moving box with a base area of 324 in² and a height of 27in.
<h3>What is the volume of the moving box?</h3>
A square prism is simply a three-dimensional solid shape which has six faces that are rectangles.
The volume of a prism is expressed as;
V = w × l × h
Where w is the width, h is height and l is length
Since base area = l × w
Volume = Area × h
Given the data in the question;
- Base area = 324 in²
- Height = 27 in
- Volume V = ?
To determine the volume of the moving box, plug the given values into the above formula and simplify.
Volume = Area × h
Volume = 324 in² × 27 in
Volume = 8748 in³
Therefore, the volume of the box is 8748 in³.
Option B is the correct answer.
