2x + y = 15
A) (5, 5)
B) (7, 35)
C) (7, 0)
D) (5, -5)
(5, 5) is the solution of the system 5x – y = 20 and 2x + y = 15
Two or more expressions with an Equal sign is called as Equation.
The given equations are
5x – y = 20
2x + y = 15
______________
7x=35
Divide both sides by 7
x=5
Now plug in value 5(5)-y=20
25-y=20
Subtract 20 on both sides
25-20=y
5=y
Hence, (5, 5) is the solution of the system 5x – y = 20 and 2x + y = 15

2l + 2w ≤ 180
The length, L should be less than or equal to 60 inches whereas the width, W should be greater than or equal to 30 inches.
Inequalities refers to a system of two or more quantities in which one quantity is greater than or less than the other.
Based on the data given:
W > 0.5L
Perimeter of the blanket is given as:
2L + 2W < 180
2L + 2(0.5L) < 180
2L + 1L < 180
3L < 180
L < 60
Therefore, the length, L should be less than or equal to 60 inches whereas the width, W should be greater than or equal to 30 inches.

Answer:
44.84
Step-by-step explanation:
The formula for this is lw + l √(w/2)^2 + h^2 + w * √(l/2)^2 = h^2
After that, you just input the values to get a total of 44.84 inches
