The answer to the first question is b. n+3=7

Answer: n+3 = 7 ; 24 students

Step-by-step explanation:

When n =4

a 2n=6

(2×4) = 6

8 = 6 (Wrong)

b n + 3=7

4 + 3= 7 (Right)

c 9-n=13

9 - 4 = 13

5 = 13 (Wrong)

d n 12 = 3 n over 12 i

(4×12) = (3×4)/12

48= 1 (Wrong)

In Ms perrons class 75 percent of students are boys and there are 18 boys in the class.

Let the total number of students in the class be y.

75% of y = 18

75/100 × y = 18

0.75 × y = 18

0.75y = 18

y = 18/0.75

= 24

There are 24 students in the class.
