You multiply all the numbers by 2 to get rid of the fractions. This would leave you with k + 1 = 6. Then you subtract 1 from both sides to get k = 5.

Mrs. Cho has 24 students in her class. Some of her students are also in the play. Explain why it is not possible for exactly 24%
lora16 [44]
Let's start by calculating how many students does 24% represent.
24% * 24 = 0.24 * 24 = 5.76
We got a decimal number as solution. The reason why exactly 24% students can't be in the play is because this percentage does not represent whole number of students. She can't take 0.76 students

If she wanted 25% students to be in a play it would mean she has to take:
25% * 24 = 0.25 *24 = 6 students

Solving for y right?

2y = 3x + 4 - x
2y = 2x + 4
y = 2x + 4 over 2
y = 2 (x + 2) over 2
y = x + 2


y - 3 = 2x - 6 over 2
y - 3 = 2(x - 3) over 2
y - 3 = x - 3
y = x


x - y - 2 = 2(2x + 1)
-y - 2 = 2(2x + 1) - x
-y = 2(2x + 1) - x + 2
y = -2(2x + 1) + x - 2

6 computer R not working
24 Computers in total

Turn into fraction

6/24 (6 Top) (24 bottom)

Then simplify by 6

6 Divided By 6 is 1

24 Divided By 6 is 4

1/4 (1 top) (4 bottom)

Convert to decimal= 0.25

Move Decimal Point to the right two times

And that would get you 25%
