Find 1 second:
-----------------------------
6 sec = 540 m
1 sec = 540 ÷ 6
1 sec = 90m

Answer:
3.5 hours
Step-by-step explanation:
Distance = 21 miles
Speed * time
Speed * time = distance
Tom speed = 2 mph
Brian = 4 mph
Let time = t
Brian distance + Tom's distance = total distance
4t + 2t = 21
6t = 21
t = 21 / 6
t = 3.5 hours
Answer:
No, the denominator doesn't change when adding or subtracting fractions.
Step-by-step explanation:
-4 - 2x = -12
Add 4 to both sides, because whatever you do on the right you have to do it on the left side
-2x = -8
Divide by -2 to isolate the x to get the x value
x = 4
