Answer:
True
Step-by-step explanation:
To solve it you divide both sides by -2, which flips the inequality sign around.
Answer:
x = 910/153
Step-by-step explanation:
Multiply both sides by 7 (z = 5, so 6 +5/5 = 6 + 1 = 7):
7(3x+50*3x)/6+5/5 = 130*7
Simplify:
153x = 910
Divide by 153:
153x/153 = 910/153
Simplify:
x = 910/153
The Answer Is 540 Feet.
Angle AB is 45% of 1,200, 1/2 of the full track.
Do 0.45x1,200=540.
Let n = the hours elapsed when the two trains are 660 miles apart.
Let the first train travel east and the second train travel west.
The distance traveled by the first train is
x = (50 mi/h)*(n h) = 50n mi
The distance traveled by the second train is
y = (60 mi/h)*(n h) = 60n h
The distance between the two trains after n hours is
x + y = 50 n + 60n = 110n mi
Because this distance is 660 miles, therefore
110n = 660
n = 6 hours
Answer: 6 hours
