Answer:

9 is the number

Step-by-step explanation:

Let's call this number x

The equation is:

30+2x=48

subtract 30 from both sides and you get

2x=18

divide 2 from both sides and you get

x=9

Therefore, 30+2(9)=48

A field is a rectangle with a perimeter of 1260 feet. The length is 100 feet more than width. Find the width and length of the r
lyudmila [28]

To solve this problem you must apply the proccedure shown below:

1. The formula for calculate the perimeter of a rectangle is:

P=2L+2W

Where L is the length and W is the width.

2. The length is 100ft more than the width, therefore:

L=W+100

3. Substitute values into the formula for calculate the perimeter and solve for the width:

1260=2(W+100)+2W\\ W=265ft

3. Then, the length is:

L=265ft+100ft\\ L=365ft

The answer is: The length is 365ft and the width is 265ft
