Answer:
48 pupils
Step-by-step explanation:
let the number of people in the class be x
⅚ of the number of pupils in a class is expressed as ⅚x
4 greater than three-quarters of the number in the class is expressed as 3/4x+4
Equating both expressions
⅚x = 3/4x + 4
5x/6 - 3x/4 = 4
(10x-9x)/12 = 4
x/12 = 4
x = 4*12
x = 48
Hence the number of pupils in the class is 48 pupils
Answer:
B?
Step-by-step explanation:
Using the absolute value function, we have that:
- The absolute value inequality is: |x - 5| ≤ 0.2.
- The compound inequality is 4.8 ≤ x ≤ 5.2.
<h3>What is the absolute value function?</h3>
The absolute function is defined by:
It measures the distance of a point x to the origin.
The diameter must be at least 4.8mm and at most 5.2mm, hence the compound inequality is:
4.8 ≤ x ≤ 5.2.
Another interpretation is that they are at most 0.2 mm from 5 mm, hence the absolute value inequality that models the situation can be given by:
|x - 5| ≤ 0.2.
