A building in a city has a rectangle base. The length of the base measures 70 feet less than three times the width. The perimete
igor_vitrenko [27]

Answer:

Width 130 ft and

Length 320 ft

Step-by-step explanation:

We are given;

  • Length of the rectangular base is 70 ft less than three times the width;
  • Perimeter of the rectangular base is 900 ft

We are required  to determine the dimensions of the rectangular base;

Assuming the width of the rectangular base is x ft

Then length will be (3x - 70) ft

But;

Perimeter = 2L + 2W

Thus;

900 ft = 2(3x-70) + 2(x)

900 ft = 6x -140 +2x

1040 = 8x

 x = 130

Thus;

Width = 130 ft

Length = 3x -70 = 320 ft

Hence the dimensions of the rectangular base are width 130 ft and length 320 ft

Find two numbers whose sum<br> is 37 and difference is 9.
JulijaS [17]

Answer:

23 and 14

Step-by-step explanation:

The sum of x and y is 37. In other words, x plus y equals 37 and can be written as equation A:

x + y = 37

The difference between x and y is 9. In other words, x minus y equals 9 and can be written as equation B:

x - y = 9

Now solve equation B for x to get the revised equation B:

x - y = 9

x = 9 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 37

9 + y + y = 37

9 + 2y = 37

2y = 28

y = 14

Now we know y is 14. Which means that we can substitute y for 14 in equation A and solve for x:

x + y = 37

x + 14 = 37

X = 23

Summary: The sum of two numbers is 37 and their difference is 9. What are the two numbers? Answer: 23 and 14 as proven here:

Sum: 23 + 14 = 37

Difference: 23 - 14 = 9
