Answer:
48 is your answer.
Step-by-step explanation:
What you want to do is follow PEMDAS.
Parenthesis are first. You will subtract 32 and 8 to get 24.
6 x [(24)/4+2] You will then divide 24 and 4 to get 6.
6 x[6+2] you will then add 6+2 to get 8.
6 x 8 = 48 is your answer.
Substitute on equation 2, y = -4x + 7. so equation 1 becomes 2x - (-4x + 7) = 6x - 7 = 5. 6x = 12, so x = 2. from above, y = -4x+7 = -4(2) + 7 = -1

Answer:
Angle A = 100°
Angle B = 80°
Step-by-step explanation:
Supplementary angles means angles add up to 180°.
There are only two angles given here.
Angle A and Angle B add up to 180°.
A + B = 180°
4x + (2x + 30) = 180°
4x + 2x + 30 = 180°
6x + 30 = 180°
6x = 180 - 30
6x = 150°
x = 150 ÷ 6
x = 25°
Now substitute the x value to the angles.
Angle A:
4x
4(25) = 100°
Angle B:
2x + 30
2(25) + 30
50 + 30 = 80°
