Between each point of "5" there are 10 little squares in between and each number passes every 2 little squares. So we can use this to solve the questions.
Part A:
Count all the pupils who scored "more" than 7 using the assumption we made above.
12 scored more than 7
Part B:
Since we know that 14 scored more the seven, count all of the pupils who scored 7 and less.
15 scored a seven or less.
Add both numbers.
12 + 15 = 27 total pupils
Part C:
The assumption we had to make was to count each two little squares that represent one pupil to find the answer for Part B.
Best of Luck!
Answer:
7x³ + 13x²+ 8x +9
Step-by-step explanation:
(3x² + 2x + 7x³) + (10x² + 6x + 9)
= 3x² + 2x + 7x³ + 10x² + 6x + 9
= 7x³ + (3x²+ 10x²)+ (2x+ 6x) +9
= 7x³ + 13x²+ 8x +9
Answer: I think the answer is 1250.
Step-by-step explanation:
I did 200 divided by 4 which is 50. I then multiplied 50 * 25 and got 1250.
