Answer:
x = 35°
Step-by-step explanation:
assuming that the straight line at the bottom of the figure is actually a straight line, that means all the angles along that straight line must add up to 180 °
i.e.
40 + (2x+30) + 40 = 180
40 + 2x+30 + 40 = 180
110 + 2x = 180 (subtract 110 from both sides)
2x = 180 - 110
2x = 70
x = 35
Answer:
Answer is below
Step-by-step explanation:
Subtract 4 from both sides.

Divide both sides by -6.

Answer:
y=2x+8
Step-by-step explanation:
You set the slope to the opposite of -1/2 which is 2/1 or 2.
Then you do b=2(4) (because 4 is the x in the coordinate points)
and solve for b you get 8 so
Y=2x+8
Answer:
D. 13
Step-by-step explanation:
54 ÷ 3 = 18 (your age in 5 years)
18 - 5 = 13 (your age now)
