Tim spends 500 minutes at the school.

Step-by-step explanation:

Given,

Time for lunch = 45 minutes

Time for study hall = 45 minutes

Total = 45+45 = 90 minutes

This represents 18% of the total minutes Tim spend at school.

Let,

x be the total minutes Tim spend at school.

18% of x = 90 minutes

\frac{18}{100}x=90\\\\0.18x=90

Dividing both sides by 0.18

\frac{0.18x}{0.18}=\frac{90}{0.18}\\x=500

Tim spends 500 minutes at the school.

There are 18 boys in a class there are w fewer boys than girls how many students are there in the class
Pachacha [2.7K]
The Number of boys in the class is: 18

 Let's call "g" to the number of girls in the class.

 The problem says that there is "w" fewer boys than girls, so we have:

 g-w=18

 Then, the number of girls in the class  is:

 g=18+w

 Let's call "x" to the total number of studens in the class:

 x=g+18

 When we substitute g=18+w  into x=g+18, we obtain:

 x= (18+w)+18

 The total number of studens in the class is:

 x=w+36
