Answer:
(-4, -1)
Step-by-step explanation:
-3x - 8y = 20; y = 5x + 19
y = 5x + 19; -3x - 8y = 20
y = 5x + 19
-3x - 8y = 20
-3x - 8(5x + 19) = 20
-43x - 152 = 20
-43x - 152 + 152 = 20 + 152
-43x = 172
-43x / -43 = 172 / -43
x = -4
y = 5x + 19
y = (5)(-4) + 19
y = -1

Answer:
n = 2
Step-by-step explanation:
In order for the ratio to have a value of 1, the sum of exponents in the numerator must equal the sum of exponents in the denominator:
n + 7 = 9
n = 9 -7 . . . . . . subtract 7 from both sides of the equation
n = 2
___
Alternatively, you can simplify the given expression:
Hopefully, it is clear to you that the value of n must be 2 in order to make the numerator equal to the denominator.
I would say that the length would be 2 inches, the width to be 6 feet and the area to be 144. I would say this because in order to find the area, you would need to convert 6 feet into inches. There are 12 inches in a foot. So it would be 72 inches. In order to find area you multiply the length by the width. So it would be 72 time 2, this is equal to 144. Hope this helps :)
