4x+40=180
4x=180-40
4x=140
x=35
angle A= 35°
angle B= 35(4)+40= 145°
All you do is multiply 300*.27=

Answer:
x = - 6
Step-by-step explanation:
Given
4(x + 6) - 2x = 12 ← distribute and simplify left side
4x + 24 - 2x = 12
2x + 24 = 12 ( subtract 24 from both sides )
2x = - 12 ( divide both sides by 2 )
x = - 6
Answer: (1,4)
Step-by-step explanation:
2x - 3y = -10
y = 4x
2x - 3(4x) = -10
2x - 12x = -10
-10x = -10
x = 1
y = (4)(1)
y = 4
Double Check:
2(1) - (3x4) = -10
2-12 = -10
-10 = -10
