9.
2x+3+x+9 = 180 => 3x = 168 => x = 56;
m(<ABD) = 2*56 + 3 = 115.
Answer:If it's adding the answer will be 8/12 if it must be simplified =2/3
Step-by-step explanation:
First you time 1/4 by 3 and then you add.
4x + 8y = 40
4x + 8(0.8) = 40
4x + 6.4 = 40
40 - 6.4 = 33.6
33.6 / 4 = x
33.6 / 4 = 8.4
The answer option 2, 8.4
