Answer:

x = 20\\m\angle 3 = 115\degree \\m\angle 5 = 65\degree \\

Step-by-step explanation:

m\angle 3 + m\angle 5= 180\degree \\(interior \:\angle\:Postulate) \\(x + 95) \degree +(3x + 5) \degree = 180\degree \\(4x + 100)\degree = 180\degree \\4x + 100 = 180\\4x = 180-100\\4x = 80\\x = \frac{80}{4}\\\huge \red {\boxed {x = 20}} \\\\m\angle 3 =(x + 95)\degree \\m\angle 3 =(20 + 95)\degree \\\huge \orange {\boxed {m\angle 3 =115\degree}} \\\\m\angle 5 = (3x + 5)\degree \\m\angle 5 = (3\times 20+ 5)\degree \\m\angle 5 = (60+ 5)\degree \\\huge \purple{\boxed {m\angle 5 = 65\degree}} \\\\

2a - b = ac + 3b for a
DaniilM [7]

Answer:

If your trying to solve for a, I believe this is the answer: a = 4b / (2 - c)

Step-by-step explanation:

2a - b = ac + 3b

First you want to group by like terms, so for "b" you are going to add "b" to both sides so that it cancels out on the left side and you now have all of your "b's" on the right.

2a = ac + 4b

next, you want to get the a's on the left side so you are going to subtract "ac"

2a - ac = 4b

Now, you need to factor the "a" out, and since its the greatest common factor among the "2a - ac" you are left with "a(2 - c)"

a(2 - c) = 4b

Finally divide both sides by "(2 - c)"

a = 4b / (2 - c)

and that's your answer

What is the constant of variation, k, of the direct variation, y = for, through (5,8)?
Rashid [163]

Answer:

\frac{8}{5}

Step-by-step explanation:

The constant of direction variation givens a proportion that is maintained by both x and y values for all points of a line that it passes through.

Usually represented with the variable k, it is given by:

\frac{y}{x}=k for coordinates (x, y).

This relationship can be written as y=kx which is also the layout for a proportional relationship.

Since coordinates are written (x, y), for point (5, 8), substitute x=5, y=8 to get the constant of variation:

8=5k,\\k=\boxed{\frac{8}{5}}
