Question

Four more than half of the students in Bryan’s homeroom have tickets to attend the school’s musical. 20 students have tickets. Select all the equations that can be used to find the number of students in Bryan’s homeroom.

Answer 1

Answer:

$4 + \dfrac{x}{2} = 20$

where x is the number of students in Bryan’s homeroom.

Step-by-step explanation:

We are given the following in the question:

Let x be the number of students in Bryan’s homeroom.

Number of students having tickets = 20

Then according to the question:

$4 + \dfrac{x}{2} = 20$

Solving the above equation, we have,

$4 + \dfrac{x}{2} = 20\\\\8 + x = 40\\x = 40-8\\x = 32$

Thus, there are 32 students in Bryan’s homeroom.
