Answer:
c
Step-by-step explanation:
m<4 and m<3 is a straight angle. straight angles are equal to 180 degrees. the friend found m<3=40 and m<4 is equal to 140 degrees (im not good at explaining, sorry)
<span>2x + 4y = 36
3x - 4y = -6
--------------add
5x = 30
x = 6
</span>2x+4y=36
2(6)+4y=36
12 + 4y = 36
4y = 24
y = 6
answer
<span>(6, 6) is a solution of equations
</span><span>(4,7) is NOT a solution of equations</span>
I can't show the work, but if the problem is printed or on the computer, I recommend using Photomath in the AppStore :)
