Question

If AB=9X-1, and AC=3x+7, find the following
x= AC=

Answer 1

Is there more?

Answer 2

Yes

Answer 3

If AC is equivalent to CB, then AB = 2(AC).

Answer 4

Using AB = 2AC, sub in the expressions for AB and AC from the problem, then solve for x. At the end, use that x value to solve for AC

Answer 5

I need help with the equation. Can you help?

Answer 6

AB=9X-1 and AC=3x+7
The whole bottom of the triangle is AB, and it is twice as big as AC, or = 2AC
So AB = 2 AC and using the top expressions,
(9x - 1) = 2(3x + 7)

Answer 7

Does that get you started?

Answer 8

yes thank you!
