Answer:
x=12
Step-by-step explanation:
First you make sure x is on both sides of the equation. So you do 0.7x-5-0.2x=0.2x+1-0.2x. Which just simplifies to 0.5x-5=1. You make sure x is the only thing on that side of the equation so you do 0.5x-5+5=1+5 which simplifies to 0.5x=6. Multiply the equation times 2 to just have x. x=12. The value that makes true of x is 12.

Answer:
   d.  AB = 54
Step-by-step explanation:
The triangle is isosceles, so AB = AC.
   (4x +6) = (5x -6)
   12 = x . . . . . . . . . . . . add 6-4x to both sides
Then the length of AB is ...
   AB = 4x +6 = 4(12) +6 = 48 +6
   AB = 54
