4c + 5c = 92 - 2
9c = 90
c = 10
22 chairs were not used in the assembly.
Answer:

Step-by-step explanation:
Given that,
The area of base, A = 24 in²
The height of the pyramid, h = 8 in
We need to find the volume of the following figure.
The volume of pyramid is given by :

Substitute all the values,

So, the volume of the pyramid is equal to
.
X^2 -5x -20=0
(x - 5/2)^2 -20 -25/4=0
(x-5/2)^2-105/4=0
(x -5/2 -(105)^1/2)(x -5/2 +(105)^1/2)=0
factors are (x -5/2 -(105)^1/2) and
(x -5/2 -(105)^1/2)
Answer:
2
Step-by-step explanation:
The slope of the line is 2. The slope is rise over run, or change in y over change in x. So to find the slope count how much each value changes, in this graph y changes +2 and x changes +1. So the slope is 2/1 or just 2. One way to visually check the slope is to remember fraction slopes will make the line flatter and other whole numbers make the line steeper.
Y = 3bx - 7x
y = x(3b - 7)
Divide each side by 3b - 7 (assume that it is not zero).
