Answer:
65 feet
Step-by-step explanation:
The problem involves finding the perimeter of a rectangle, then making adjustments to remove parts of the perimeter that aren't wanted.
The perimeter of a rectangle is given by the formula ...
P = 2(L+W)
For Aubrey's 12' × 8' room, the perimeter is ...
P = 2(12' +8') = 40'
This is the length of the border Aubrey needs at the ceiling.
__
At "waist-high", we need to subtract the total width of all the windows and doors. That total is ...
3' + 4' + 3' + 5' = 15'
So, the waist-high border is 40' -15' = 25'.
__
The total amount of border Aubrey needs is ...
ceiling border + waist-high border = 40' + 25' = 65'.
Aubrey needs 65 feet of border.
Answer:
x = 1, y = 2
Step-by-step explanation:
7x + 2y = 11 -----Equation 1
Equation 1 × 7:
49x + 14y = 77 -----Equation 2
-------------------------------------------------------------------------------------------------------------
4x - 7y = -10 -----Equation 3
Equation 3 × 2:
8x - 14y = -20 -----Equation 4
-------------------------------------------------------------------------------------------------------------
Equations 3 + 4:
49x + 14y + 8x - 14y = 77-20
49x + 8x = 77-20
57x = 57
x = 57 ÷ 57
x = 1
Substitute x = 1 into Equation 1.
7x + 2y = 11
7(1) + 2y = 11
7 + 2y = 11
2y = 11-7
2y = 4
y = 4 ÷ 2
y = 2
In a problem like this, you're looking for the lowest common multiple. Each number needs to bet multiplied into the smallest number where they all fit. So in this case, 12 years later because 12 is the lowest common multiple. Therefore, in 2022
