If T is the midpoint, then that means its exactly 1/2 of the way between 2 points
this means we can set the 2 given values equal
4x - 3 = 2x + 7
first move like terms to the same side
2x = 10
x = 5
now that we know the length of x, we plug it back in to get the length
4x - 3 + 2x + 7 = 6x + 4
6(5) + 4 = 34
I am going to assume these are points across the same line. (line segments)
If so, then jk + kl = jl
If jk is 6x and kl is 3x, we can solve for x.
6x + 3x = 27 (note we subbed 27 in for jl)
9x = 27 (divide both sides by 9 to leave on x on the left)
x = 3
CHECK! sub 3 in for x in the original problem.
6 (3) + 3 (3) = 27
18 + 9 = 27
Yes! It checks. x = 3
You can solve this by using the expressions 12+23 and 12-23.
12+23=35
12-23=-11
35 and -11 are 23 units away from 12 on a number line.

Answer:
V =84.78 inches ^2
Step-by-step explanation:
The volume of a cylinder is given by
V= pi *r^2 h
We know h= 12 inches
and r = 1.5 inches
V = pi * (1.5)^2 * 12
V = pi * 2.25*12
V = 27 pi
If we approximate by 3.14
V = 3.14 (27)
V =84.78 inches ^2
