You want to simplify or factor it?
Simplify:
7 * χ + 7 * -3 +5χ
=7χ + -21 +5χ
=(7χ+5χ)+-21
=12χ-21
Factor:7(x-3)+5x
12x-21
=3(4x-7)
A straight line = 180 degrees.
Subtract the 2 known angles from 180:
180 - 112 - 38 = 30 degrees
Its 11.5 because your adding everything in your equation or question
1 worker = 30 hours a week
1 worker = 30 x $5.50 a week = $165
1 worker = $165
1000 workers = 165 x 1000 = $165 000
