Step-by-step explanation:
Let the total number of students in the choir be x
24℅ of x = 12
24/100 of x = 12
6x/25 = 12
6x = 12× 25
6x = 300
x = 50
Answer:
the answer is 23 and 24
Step-by-step explanation:
I just did the middle school test and that was the correct answer.
Answer:
4 hours and 15 minutes
Step-by-step explanation:
We have to find out how long it will take a driver to complete the route.
Time of start the route = 9:50 A.M.
Time of finish = 2:05 P.M.
We can convert the time of finish in 24 hours time
2:05 P.M = 14:05
Now we subtract start time from finish time.
14:05
- 09:50 [borrow 60 minutes to subtract 50 from 05]
04 : 15
It takes 4 hours and 15 minutes to drive the route.
For this case we can write the following linear expressions:
We now subtract both linear expressions:
From here, we must subtract similar terms.
We have then:
Rewriting we have:
That is, we obtain the desired result.
Answer:
2 linear expressions whose difference is 5x-4 is:
