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

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
