Answer:
x = -
Step-by-step explanation:
<u>Method 1:</u>
1. Original Equation: -x =
2. Multiply by 9 on both sides: -x =
Whatever you do to one side you have to do to the other. You would multiply by 9 on both sides because the LCD of 3 and 9 is 9. You want to make it where you can get rid of the fraction.
3. Simplify: -x =
Simplify the numerators of both fractions.
4. Simplify: -4x = 6
Divide both of your fractions to simplify them.
5. Divide: x = -
Divide by -4 on both sides to get x by itself.

we know there are 180° in π radians, how many degrees then in -3π/10 radians?
Answer:
Step-by-step explanation:
4) parallel because 118° is a supplement to 62° and the corresponding angles are both 118°
5) NOT parallel. The labeled angles sum to 120° and would sum to 180° for parallel lines.
6) NOT parallel. see pic.
If parallel, extending a line to intersect ℓ₁ makes an opposite internal angle which would also be 48°. The created triangle would have its third angle at 180 - 90 - 48 = 42° which is opposite a labeled 48° angle, which is false, so the lines cannot be parallel
7)
b = 78° as it corresponds with a labeled angle above it
a = 180 - 78 = 102° as angles along a line from a common vertex sum to 180
f = is an opposite angle to 180 - 78 - 44 = 58° as angles along a line from a common vertex sum to 180
e = 180 - 90 - 64 = 26° as angles along a line from a common vertex sum to 180
c = 58° as it corresponds with f
d = 180 - 58 = 122° as angles along a line from a common vertex sum to 180
