The answer to your question is 2.
Step-by-step explanation:
3528 ÷ 30 = 117.6
He should travel 117.6 m in one minute
The number of large boxes is 4 and the number of small boxes is 14.
<u><em>Explanation</em></u>
Suppose, the number of large boxes is
and the number of small boxes is 
As, the total number of boxes is 18, so the first equation is....

The large boxes hold 35 books, and the small ones hold 20 books and the total number of books is 420. So the second equation will be .....

Now solving equation (1) for
itself , we will get....

We will plug this
into equation (2). So.....

Now plugging this
into the equation
.......

Thus, the number of large boxes is 4 and the number of small boxes is 14.

<h3><u>Part A: An equation to represent this situation, where x represents the original length of the rectangle is:</u></h3>

<h3><u>Part B: Original length of the rectangle is 12 inches</u></h3>
<em><u>Solution:</u></em>
Given that,
A rectangle has a width of 2.5
Therefore,
width = 2.5 inches
Let "x" be the original length of the rectangle
When the length of this rectangle is decreased by 5 inches
Therefore,
New length = x - 5
The new area of the rectangle is 17.5 square inches
Therefore,
<em><u>The area of rectangle is given as:</u></em>


Thus original length of the rectangle is 12 inches
