Answer:
Step-by-step explanation:
Let x be the original number.
x - 15 - 1/2(x - 15) - 10 = 12
x - 15 - 1/2 x + 7.5 - 10 = 12
1/2x - 25 + 7.5 = 12
1/2x - 17.5 = 12
1/2x = 27.5
x = 55
Since the exponent of 2x is 1:
![2x^1](https://tex.z-dn.net/?f=2x%5E1)
It's
Linear
Hope this helps!!
Answer:
A.(AB/BC)=(CE/ED)
Step-by-step explanation:
Properties of Similar Triangles states two things
Corresponding angles are congruent (same measure)
Corresponding sides are all in the same proportion
That means AB/ BC = CE/ED
