Answer:
truck is 100mph
Step-by-step explanation:
-2/3(2x-1/2) ≤1/5x-1
Simplify the left side:
-4/3x+1/3 ≤1/5x-1
Subtract 1/5x from each side:
-23/15x + 1/3≤-1
Subtract 1/3 from each side:
-23/15x ≤-4/3
Divide both sides by -23/15:
X = -4/3 / -23/15
X ≥ 20/23
Convert to interval notation:
[ 20/23 , ∞)
So since angle A is 120, so angles B+C=60 because there are 180 degrees in a triangle. So B:C is 2:1. So angle B is 40 and angle C is 20.
Answer:
a=9
b=4
v=69
Step-by-step explanation:
The answer will be the second one.
3 1/4 + 2 5/6 can be rewritten to 3 3/12 + 2 10/12 so both denominators are the same. Add them up and you get 6 1/6 miles.
