-(-5 - 6x) = 4 (5x +3)
Pretend that there is a -1 in front of the first bracket
-1(-5-6x)= 4(5x+3)
Mutiply the first bracket by -1
(-1)(-5)(-1)(-6x)= 5+6x
Mutiply the second bracket by 4
(4)(5x)(4)(3)= 20x+12
5+6x= 20x+12
move 20x to the other side
5+6x-20x= 20x-20x+12
5+6x-20x= 12
5-14x= 12
move 5 to the other side
sign changes from +5 to -5.
5-5-14x= 12-5
-14x=7
divide by -14
-14x/-14= 7/-14
x= -1/2
Answer: x= -1/2
Answer:
1 1/2

Answer= 6.5in
Lets write down the data we know.
People=4
Length of subs=13+13=26inches
To solve for how many inches each person gets, we divide the length of the sub, 26in, by the number of people sharing it, 4.
26/4=6.5
So each person gets 6.5 inches of the sub
7 and a half hours
Explanation-
8/5=1.6
12/1.6=7.5
Volume of cube = 1/3 * pi * r^2 * h
83.74 = 1/3 x 3.14 x r^2 x 5 = 5.233r^2
r^2 = 83.74/5.233 = 16
r = sqrt(16) = 4
Answer: d = 2(4) = 8 inches.
