Answer:
Step-by-step explanation:
The angles are complimentary, so they add to 90
6x + 3 + 7x + 9 = 90 Combine like terms
13x + 12 = 90 Subtract 12 from both sides
13x = 90 - 12 Combine
13x = 78 Divide both sides by 13
x = 6
<A = 6x + 3
<A = 6*6 + 3
<A = 36 + 3
<A = 39
14 pounds 9 ounces = 233 ounces
9 pounds 14 ounces = 158 ounces
233-158=75 ounces=4 pounds 11 ounces
The third one should be -2(2x-6)=12-4x
Last one should be 2(2x-6)+4x=8x-12
