3x-4y=10
-20-x+2y=10 then -30+2y=x now plug this in the other equation:
3(-30+2y)-4y=10
-90+6y-4y=10
2y=100
y=50
12 = 60 degrees.
The "C" pattern means that whatever is on the top/bottom corner will be equal to the opposite one.
(-2.9a + 6.8) + (4.4a - 7.3)
= -2.9a + 6.8 + 4.4a - 7.3
Combine like terms. All "a" terms can only be added to other "a" terms, and all non variable terms can only be added to other non variable terms.
= 1.5a - 0.5
Final Answer: D. 1.5a - 0.5
