Well we can find the perimeter by using the formula P=2L + 2W
P=2(30) + 2(18) P=60+36 P=96
I believe we can divide the perimeter by 18 to find the total amount of lights needed.
96÷18=5.333333
So we know at least 5 lights are needed.
I'm not sure if I'm correct, but I hope this helped anyways :)

What is the value of x, given the following system of linear equations? x + y = 8 and x - y = 2

zaharov [31]

Answer:

$x = 5$

Step-by-step explanation:

$x + y = 8 \\ x - y = 2 \\ x + y + (x - y) = 8 + 2 \\ x + y + x - y = 10 \\ 2x = 10 \\ \frac{2x}{2} = \frac{10}{2} \\ x = 5 \\ \\ x + y = 8 \\ 5 + y = 8 \\ y = 8- 5 \\ y = 3 \\ \\ x - y = 2 \\ 5 - 3 = 2 \\ 2 = 2$
