Answer:
C
Step-by-step explanation:
First we distribute (-2,3) into the equations so 2x+4y becomes 2(-2)+4(3) so that's -4+12 which is 8 making equation 1 correct.
Then x+2y becomes (-2)+2(3) which is 4 so the second equation is correct as well therefore the answer has to be C because of process of elimination
Answer:
-14
Step-by-step explanation:
if n = 1.5, replace all letters labeled "n" with 1.5
5(1.5) - (20 +1.5)
5 x 1.5 = 7.5
(20+1.5) = 21.5
7.5 - 21.5 = -14

Answer:
I'm sorry, I can help only with this one x = 20°
Step-by-step explanation:
2x + 5° + 4x + 15° + 2x = 180°
8x = 180° - 5° - 15°
8x = 160°|÷8
x = 20°
