Answer:
The length is 6 feet and the width is 4 feet
Step-by-step explanation:
Let x represent the length of the yard
The width can be represented by x - 2, since it is 2 less than the length.
Use the perimeter formula, P = 2l + 2w, where l is the length and w is width
Plug in the expressions and perimeter:
20 = 2x + 2(x - 2)
Solve for x:
20 = 2x + 2x - 4
20 = 4x - 4
24 = 4x
6 = x
So, the length is 6. Plug this into x - 2 to find the width
x - 2
6 - 2
= 4
So, the length is 6 feet and the width is 4 feet
Answer:
0,1,2
Step-by-step explanation:
(x+2) = 2((x+1)+(x)
x+2 = 2x+2+2x
x+2 = 4x+2
-x -x
2 = 3x + 2
-2 -2
0/3 = 3x/3
0 = x
Answer:
x=4-5/3y
Step-by-step explanation:
3x+5y=12 make x on one side
3x=12-5y divide everything by 3
x=4-5/3y
The first step in calculating the mean is to add the numbers. After that you divide by the number of items in the data set. You don’t need to group the numbers to find the mean. Hope this helped!
