Supplementary angles will always add up to 180. If you had a straight line, and you drew another line across that line, the two angles on either side of that line would add up to 180 because a flat line is equal to 180 degrees.
Step-by-step explanation:
Solve for a:
Step 1: Multiply both sides by b.
b=a
Step 2: Flip the equation.
a=b
---------------------------
Solve for b:
Step 1: Multiply both sides by b.
b=a
Slope intercept form is

, where 'm' is the slope and 'b' is the y-intercept.

Subtract 6x to both sides:

Divide 5 to both sides:
Answer:
About 113
Step-by-step explanation:
Well, there are about 453 grams in a pound.
So divide 453 by 4, and there's the answer!
453 / 4 ≈ 113
