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
I got -1/48 but that could be wrong
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
1 large drink cost $1.65
Work: 16.95 - 12.00 = 4.95 <- Cost of drinks
Then 4.95 divided by 3 = 1.65
So it is $1.65 per large drink.
Hope I was able to help!
Answer:
1,980 would be the area and the perimeter would be 39 im pretty sure
