Answer:
−21
Step-by-step explanation:
=12s5t−6t4−6s−21
The answer is 3x^2 + 19x - 12.
Your answer is 2,200 pupils.
If 990 is equal to 45% of the total amount of pupils, then to find 1% we can divide both 45 and 990 by 45.
990 ÷ 45 = 22, which is 1%, so then we multiply 22 by 100 to get 100% of the pupils, which gives us 2,200.
I hope this helps!
So 25 goes into 21 how many times? 1. Add that 1 to the 3 making 4.
Then how much is left over of the 25 & 21? 4.
Making it 4 4/21
