Answer: X = 4
Step-by-step explanation: To solve for k in this equation, we want to get k by itself on the left side of the equation.
Since k is being multiplied by 5, to get k by itself, we need to divide by 5 on the left side of the equation. Since we divided by 5 on the left side, we must also divide by 5 on the right side.
On the left side, notice that the 5's cancel out, so we are simply left with z. On the right side, we have 20 divided by 5 which gives us 4.
Now we have X = 4.
Finally, remember to check your answer by substituting a 4 back into the original equation.
So we have 5 (4) = 20 which is a true statement.
This means that our answer, x = 4 is correct.
21 could be wrong but 5 players get 4 wins each before the one players gets the last needed win

Answer:
≈ 197 students
Step-by-step explanation:
Let's start by writing what we know.
150 students sampled
68 prefer soccer
59 prefer basketball
23 prefer swimming
Part A
If 59 students prefer basketball out of the 150 students sampled then we divide 59/150 in order to get the percentage of students that prefer basketball.
59/150 ≈ 39.33% Remember this is only a sample of the students so it is approximate.
Now that we have the percentage, we can multiply it by the entire student body to get an approximate number of all students that prefer basketball.
39.33% = .3933
.3933 * 500 = 196.66 ≈ 197 students (because we can't have a partial student we round up)
2x -4y= 28
⇒ -4y= 28 -2x
⇒ y= (28 -2x)/ (-4)
⇒ y= 28/(-4) -(2x)/ (-4)
⇒ y= -7 + 1/2x
The final answer is y= -7 + 1/2x~
