Answer:

The expressions are equivalent.

Step-by-step explanation:

We can simplify each expression and compare the results.

(x + 10) + x + 9 = x + 10 + x + 9 = 2x + 19

2(x + 7) + 5 = 2x + 14 + 5 = 2x + 19

2x + 19 = 2x + 19

Answer: The expressions are equivalent.

How do I solve for y?
Allisa [31]

First we know that,

3x+15=5x-65 because of vertical angle thr.

y=y because of reflex property

there are 360 degrees in a circle so..

3x+15+5x-65+2y=360

3x+15=5x-65

x=40

so each 2 of the angles are...(40*3+15)=135

Then your new equation is

135+135+2y=360

2y=90

<u>y=45</u>

Hope this helps :)
