Answer:
-2
Step-by-step explanation:
24 - 4x =32
-4x =32 - 24
-4x=8
x=-8 :4
x=-2
For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
Answer:
the equation that will help find the time it takes chelsea to get to school on the bus is:
45 * t = 2.5 * (1-t)
Note: the equation will have one solution.
Answer:
6 mins
Step-by-step explanation:
An ant can crawl 3/4 of a yard in 1/2 minute. How long will it take for the ant to crawl 12 yards?
Ant crawls 3/4 of a yard in = 1/2 min = 60/2 sec = 30 sec
Ant crawls 12 yards in = 12 * 30 = 360 sec = 360/60 = 6 minutes
Answer:
d=5
Step-by-step explanation:
1. use the distance formula: d=
2. plug in the points: d=
3. solve problem inside parentheses: d=
4. square -4 and -3: d=
5. add:d=
6. find square root: d=5
Hope this will help u....
