-3x+20=2
move +20 to the other side
sign changes from +20 to -20
-3x+20-20= 2-20
-3x= 2-20
-3x= -18
divide both sides by -3
to get +x and x by itself
-3x/-3= -18/-3
Answer:
x= 6
Answer:
C
Step-by-step explanation:
Given a line with slope m then the slope of a line perpendicular to it is
= -
Given the slope of the red line is 4 , then the slope of the green line is
m = - → C
If LllM then the consecutive angles shoud be supplementary(=180)
x-5+2x+5=180
x+2x=180
3x=180
x=60
Answer:x=60
