Answer:

∠MON = 99

Step-by-step explanation:

∠LON = 180°

∠MON + ∠LOM = 180 -------equation

where:

∠MON = 8x - 13

∠LOM = 7x - 17

plugin values into the equation

8x - 13 + 7x - 17 = 180

8x + 7x - 13 - 17 = 180

15x - 30 = 180

15x = 180 + 30

x = 210 / 15

x = 14

plugin values to ∠MON = 8x - 13

∠MON = 8x - 13

∠MON = 8(14) - 13

∠MON = 99

I need help showing steps to solve 36v-12=12
Ad libitum [116K]
36v - 12 = 12 .....add 12 to both sides
36v - 12 + 12 = 12 + 12...simplify
36v = 24...divide both sides by 36
(36/36)v = 24/36
v = 2/3 <===

Which ordered pair is a solution of the equation
Mrrafil [7]

Answer:

A

Step-by-step explanation:

y - 3 = 5(x - 2)

y - 3 = 5x - 10    Add 3 to both sides

y = 5x - 7

Let x = 2

y = 5*2 - 7

y = 3

So (2,3) works

Let x = 3

y = 5*3 - 7

y = 15 -7

y = 8

The answer is A
