There is 7,000 female students, and 5,000 male students. Because, if there was 2,000 more female students then male, you have to find out what two numbers add up to 12,000. (Tip, to make it easier, take away the thousands, like 7+5)
To work out percentage, divide what they've done (21) by the total distance (50), then multiply it by 100 to get the percentage
(21/50)*100 = 42%
The y-intercept of the graph is 0
This question is impossible to answer without knowing or being able to see the question.
17y -24y +13y -y = 210
(17-24+13-1)y = 210
5y=210
y=42
