Answer:
25 students
Step-by-step explanation:
Let t= total students
Take the total number of students and multiply by the percent that are boys to get the number of boys
t * 40% = 10
Change to decimal form
t*.40 = 10
Divide by .4 on each side
.40t /.4 = 10/.4
t =25

Answer:
Move the decimal.
Step-by-step explanation:
Multiply by 10, move decimal place one place to the left. Divide by ten, move one to the right.
Subtract 12 from both sides
5 - 12 = k/4
Simplify 5 - 12 to -7
-7 = k/4
Multiply both sides by 4
-7 * 4 = k
Simplify -7 * 4 to -28
-28 = k
Switch sides
k = -28
