<u>Answer:</u>
- The simplified expression is "7p/4 + 2 1/2" or "1.75p + 2.5".
<u>Step-by-step explanation:</u>
- 2p + 3/4p + 6 - p - 3 1/2
- => (2p - p + 3/4p) + (6 - 3.5)
- => 1.75p + 2.5
Hence, the simplified expression is "<u>7p/4 + 2 1/2</u>" or "<u>1.75p + 2.5</u>". Any of these would work.
Hoped this helped.
Answer:
The answer to your questions is: 25 new teachers
Step-by-step explanation:
Data
# of students = 2000
ratio = 3:80 teachers to students
New teachers = ?
Process
I suggest to use rule of three to solve this problem
3 teachers ---------------- 80 students
x ---------------- 2000 students
x = (2000 x 3) / 80 = 75 teachers
Number of initial teachers = 75
The ratio change to 1:20
1 teacher ------------------- 20 students
x ------------------- 2000 students
x = (2000 x 1) / 20
x = 100 teachers
Number of new teachers = 100 - 75 = 25
