Answer:
A measures 72 and B measures 108
Step-by-step explanation:
If the angles are supplementary, that means that they add up to equal 180. 3x + 12 + 4x + 28 = 180. Doing some algebra there gives you that 7x = 140 and x = 20. Sub in 20 to angle A to get 3(20) + 12 = 72, and sub in 20 to angle B to get 4(20) + 28 = 108. And of course, 108 + 72 = 180.
Answer:
x = 1000
Step-by-step explanation:
5,350 ÷ x = 5.35
To find this you should divide 5,350 by 5.35.
5,350 ÷ 5.35 = 1000
x = 1000

He moved it at 30ft./minute
Answer:
(x - 1) x (5x + 4)
Step-by-step explanation:
5 x 2 – 4 = 6
5 x 4 – 4 = 16
6 x 2 – 11x – 4 = 56
5 x 2 – x – 4 = (x - 1) x (5x + 4)
