Answer:
21+8x
Step-by-step explanation:
7(3 – X) + 15x
21-7x+15x
21(-7x+15x)
21+8x
Answer:
(X ✖ 3)+(2 ✖ X)
Step-by-step explanation:
When x equals 2 x times 3 equal 6 then plus 2 times 2 equals 10
The numerical length of the line segment ST is 3.
<h3>What is the numerical length of a line segment?</h3>
Herein we have a line segment formed by three points collinear to each other. Mathematically speaking, we find the following condition:
SU = ST + TU
4 · x = (2 · x + 1) + (5 · x - 4)
4 · x = 7 · x - 3
3 · x = 3
x = 1
And the numerical length of the line segment ST is:
ST = 2 · 1 + 1
ST = 3
The numerical length of the line segment ST is 3.

3 - 4 = - 10
3 x = - 10 + 4
3 x = - 6
x = - 6/3 = - 2
<span>96-2r=6r-112
Add 2r to both sides
96=8r-112
Add 112 to both sides
208=8r
Divide 8 on both sides
Final Answer: 26=r</span>
