9. Ms. Abbott's 6th grade class has 18 students with brown eyes and 15 students with blue eyes. Ms. Downey's 6th grade class has 12 students with brown eyes and 10 students with blue eyes. What is the ratio of the students with brown eyes to the total number of 6th grade students?
a.
3/5
c.
6/11
b.
11/6
d.
5/3

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

need more info

step-by-step explanation:

what do you mean by "representation"? graph? table? etc.

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
