Start with the ()
5h-3j-k since you cant add any further u just multiple the second neg in the []

-5h+3j+k+2k you can add ONLY the K

-5h+3j+3k now multiply the neg again this time tih the {}

3j+5h-3j-3k The 3J is canceled out b/c 3j-3j=0
Giving you a total of 5h+3k

There are 32 students in a class. Of the class, 3/8 of the students bring their own lunches. How many students bring their lunch

OverLord2011 [107]

Answer:

The number of students that bring their lunches is 12

Step-by-step explanation:

Let

x -----> the number of students that bring their lunches

y -----> the total number of students in a class

we know that

The number of students that bring their lunches divided by the total number of students in a class must be equal to 3/8

$\frac{x}{y}=\frac{3}{8}$

$x=\frac{3}{8}y$ -----> equation A

$y=32$ -----> equation B

substitute the value of y in equation A and solve for x

$x=\frac{3}{8}(32)$

$x=12$

therefore

The number of students that bring their lunches is 12
