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
Answer:
Step-by-step explanation:
18x-2 = 17x +2
⇒18x-17x - 2 = 2
⇒x - 2 = 2
∴ x = 4
Hello, and welcome to Brainly!
It seems y ou want to find the value of x in the expression -4x + 7 - 6 = 22.
If that's the case, combine the 7 and -6, obtaining: -4x + 1 = 22. We want to isolate x. To achieve this, subtract 1 from both sides, obtaining -4x = 21.
Dividing both sides of this equation by -4 gives us x = (-21)/4.
This is the "solution" of the given equation.
