Answer:
x = 30
Step-by-step explanation:
Vertical angles have equal measures, so ...
2x +10 = 70
2x = 60 . . . . . . subtract 10
x = 30 . . . . . . . divide by 2
Answer:
8
Step-by-step explanation:
It's clear that the ratio of the weight and cost is 1:2.
So when you increase the factor by 4 , the cost increases by 8.
That's all I can say, and I'm sure my answer is correct.
Answer:
55
Step-by-step explanation:
Because of the parallel lines (marked by those arrows) we know that the corner angles are the same:
110 - x = x so
110 = 2x
55 = x
Answer:
D. y=-3x+8
Step-by-step explanation:
first, get the 12x on the other side of the equation
12x+4y-12x=32-12x
4y=-12x+32
divide the equation by four
y=-3x+8
