IF ONE THIRD OF THE SCHOOL STUDENTS LIKE MATHEMATICS AND 400 STUDENTS DO NOT LIKE MATHEMATICS , THEN HOW MANY STUDENTS DOES THE SCHOOL HAVE ? A. 600 B. 800
C. 200 D. 1000

A. 600

Step-by-step explanation:

1/3 like it, so that means 2/3 doesn't like it.

2/3 is 400, so that means that if you take the whole number of students, divide it by 3 and then multiply by 2, the result will be 400, so let's do the inverse way to find how much is 3/3

divide something by 3 and then multiply by 2 to have 400, which number we can multiply by 2 to have 400? It's 200

And now, which number we can divide by 3 to have 200? it's 600

1010: 3030

is it i think

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
