x= 8
Answer:
∠ B = 126°
Step-by-step explanation:
Since the lines are parallel, then
∠ A = ∠ B ( alternate angles ), thus
8x + 78 = 2x + 114 ( subtract 2x from both sides )
6x + 78 = 114 ( subtract 78 from both sides )
6x = 36 ( divide both sides by 6 )
x = 6
Thus
∠ B = 2x + 114 = 2(6) + 114 = 12 + 114 = 126°
Answer:
58.5
Step-by-step explanation:
Distance = rate * time
so if it's 4.5 hours:
Distance = 13 mph* 4.5 hours
= 58.5 miles
Answer:

Expand the brackets by multiplying everything in the brackets by 4
4x+4-2x
simplify
2x+4
