Answer:
B - 59 degrees
Step-by-step explanation:
In total there is 360 degrees, 131 + 170 = 301, 360 - 301 = 59
first we multiply both sides by 3, so we get 42=4y-6x, because the division and multiplication cancel each other out, then we move the variable to the other side, so we subtract 4 on both sides and cancel out 4y-4y, so we and up with -4y=-6x-42, then we can divide both sides by -4, so:
final answer: y=3/2x + 21/2
Answer:
according to me its just multiplying with the number ( -2)
like 9×(-2) = -18
36×(-2) = -72
70+80+(m+10)= 180°
150+m+10=180
160+m=180
m=20°
Answer:
x=-10
Step-by-step explanation:
2(x+3)=x-4
2*x+2*3=x-4
2x+6=x-4
2x-x=-4-6
x=-10
