Honestly bro i'm not sure i think it's because y=mx+b
Answer:
4
Step-by-step explanation:
Just plug in -9 to the equation
6(-9) + 9y = -18
-54 + 9y = -18 isolate 9y
54 - 54 + 9y = -18 + 54
9y = 36 isolate y
9y/9 = 36/9
y = 4
Answer:
88 or 1 minute and 28 seconds
Step-by-step explanation:
396/9= 44 times the two seconds it takes to print is 88
Answer:
Length of the room is 180 ft
Step-by-step explanation:
We have a rectangular room with dimensions:
width = 70 ft and length "x" (unknown)
Perimeter of a rectangle is 2*w + 2*x and according to problem statement 500 ft of lights will fit exactly in room perimeter then:
2*70 + 2*x = 500
140 + 2*x = 500
2*x = 500 - 140
2*x = 360
x = 360/2
x = 180 ft
The area of a square is: A = s^2
With side being s = 20m
A = 20^2m^2 = 400m^2
Hope that helps! :)
