Answer:
21 students pass
Step-by-step explanation:
Firstly, you can set up the problem into an equation where the variable X would equal the number of students passing. You put X over the total number of students in the class, turning it into a fraction, then set it equal to the fraction   (which is 75% represented as a fraction).
 (which is 75% represented as a fraction).

The fraction  can be simplified, because 75 and 100 are both multiples of 25, so after canceling out the 25s you would be left with

.

Next, you use the process of cross multiplication which is essentially just multiplying the denominators of both fractions (which would be 28 and 4 in this case) to each side of the equation. 

The denominators cancel out leaving you with a simple equation to simplify.


Finally, divide both sides by four in order to isolate the variable.

X = 21.

Answer:
<em><u>[</u></em><em><u>2</u></em><em><u>,</u></em><em><u>4</u></em><em><u>,</u></em><em><u>6</u></em><em><u>]</u></em>
Step-by-step explanation:
GIVEN EQUATION : 2X+3≥7
i.e, 2x≥7-3
i.e, 2x≥4
i.e, x≥4/2
i.e, x≥2
it's represent number should be greater than or equal to 2
The only number which follows the inequality from the set is 2,4&6
