Answer: Length = 11
Width = 9
Step-by-step explanation:
Let x represent the unknown length.
Let x - 2 represent the unknown width.
The perimeter is equal to 2 times x + (x -2)
Equation:
2 (x + (x - 2)) = 40
x + (x - 2) = 40/2
x + x - 2 = 20
2x - 2 = 20
2x -2 + 2 = 20 + 2
The length is: 2x = 22 -> x = 22/2 -> x = 11
The width is: x - 2 = 9
36x2(for the total amount of yarn for the width) would be 72. 112-72=40. Since it is a rectangle and the width should both be the same size, the length should be 20 inches. (20+20+36+36=112, so 20 inches is the correct answer.
I hope it’s correct
The answer:
5-4v=19
Is/of = %/100
x/62 = 24/100
Where x is the number of dogs and 62 is the total number of animals. 24 is the percent of dogs which is out of 100 percent of all the animals.
Answer:
A. x = 7
B. x = -3
Step-by-step explanation:
A. 5/x = 30/42
5/x = 5/7
5 = 5/7 x
5= 5x/7
5 x 7 = 5x
35 = 5x
35/5 = x
7 = x
x = 7
B. x/8 = -12/32
x/8 = -3/8
x = - 3/8 x 8
x = - 24/8
x = -3
Hope this helps you have a gr8 day :3
