Answer 1

3v+4=8v-6

Answer 2

Solve for v. input back into the original equations.

Answer 3

i have no clue how to do that i am absolutely horrible at geometry/ algebra.

Answer 4

Watch KhanAcademy videos because that is basic 6th-7th grade math.

Answer 5

you cant just give me the answer? it would make this a heck of a lot easier.

Answer 6

No I cannot, that's against OS rules.

Answer 7

3v+4=8v-6 You have to get v by itself. Do you know your first step

Answer 8

subtract 3 from both sides?

Answer 9

What makes you say that

Answer 10

i remember doing something like that

Answer 11

3v + 4 = 8v - 6

You want all terms with v on the left side, and all terms with no variable on the right side.

First, subtract 8v from both sides:

3v + 4 = 8v - 6
-8v -8v
-----------------
-5v + 4 = -6

Now we need the 4 moved to the right side, so let's subtract 4 from both sides:

-5v + 4 = -6
- 4 -4
---------------
-5v = -10

Since v is being multiplied by -5, we need to divide both sides by -5:

-5v/(-5) = -10/(-5)

v = 2

Now that we have v = 2, we insert v in the expressions used in the measure of the angles:

m<B = 3v + 4 m<Q = 8v - 6
m<B = 3(2) + 4 m<Q = 8(2) - 6
m<B = 6 + 4 m<Q = 16 - 6
m<B = 10 m<Q = 10

Answer 12

omg thank you so much if i could give you 1000 medals i would

Answer 13

You're welcome.
