Answer:
49% of the pupils are boys and 51% are girls.
Step-by-step explanation:
Alright, so first, you've got to find the total number of students: 567.
Now, to find the value of 1%, you divide 567 by 100, which will give you 5.67.
Next, you divide the number of male students by the value of 1%. That's 278 ÷ 5.67 = 49.0299823633157.
Subtracting that from 100% gives you 50.9700176366843 (percentage of girls)
Now, you can't write all that down, so you'll round it! 49.0299823633157 will round down, because 0 is less than 5, so it's 49%. 50.9700176366843 rounds up, because 9 is greater than 5, so that's 51%.
Therefore, 49% of the pupils are boys and 51% are girls.
I hope this helps!

Answer:
y=-x+6
Step-by-step explanation:
Start by graphing y=-x+5. Then mark the point (2,4) for easier reference. A parallel line just has the same slope, so if you make another line with the same slope, and change the y-intercept until the line goes through (2,4), you will have the answer.
Factor each
3x^3=3*x*x*x
21x^2=3*7*x*x
36x=2*2*3*3*x
factor out 3x
3x(x^2-7x+12)
what 2 numbers multiply to get 12 and add to get -7?
-3 and -4
3x(x-3)(x-4)
