Answer:
C. 15
Step-by-step explanation:
The following proportional can be set-up for the figure given:

Solve for x


Cross multiply


15 = 6x - 5x
15 = x
x = 15
Answer:
See attached picture.
Step-by-step explanation:
1/2 ( -3/2 + 6x + 1) - 3x
Simplify:
= 1/2 (-1/2 + 6x) - 3x
Apply distributive property:
= -1/4 + 3x -3 x
Simplify:
= -1/4
Answer:
Step-by-step explanation:
4(x+6)/(x-2)*(x+10)/24(x+6)
First we do 4(x+6)
4x+24
Then we do 24(x+6)
24x+144
So we plug it in
4x+24/x-2*x+10/24x+144
Let x the subject of the equation in x-2y=-10 this make it x=2y-10 substitute this in the first equation. 3(2y-10)-2y=-6 solve for y, y=6. substitute y in any of the original equations to get x x= 2
