Answer:
x=-5
Step-by-step explanation:
Add 22x to both sides: -8x+100=140
Subtract 100 from both sides: -8x=40
Divide both sides by -8: x=-5
So the answer is x=-5
To do this you have to divide 135 miles by 5 hours. You will get the answer of 27 miles per hour.
Answer:
10 (b+10)
Step-by-step explanation:
10b + 100
Factor out a 10
10 *b + 10*10
10 (b+10)
Use trigonometry.
sinQ = 14/50 = 0.28
-> angle Q = sin^-1(0.28) = approx 16 degrees
-> cosQ = A/H -> cos16 = PQ/50
=> PQ = 50*cos16 = approx 48.06
So yea.
