Set up a proportion.
Let x = the number of students in 29970 who speak 3 or more languages.
285/19 = 29970/x Cross multiply
285 x = 19 * 29970
285x = 569430
x = 569430/285
x = 5415 students speak 3 languages.
If n is ten then the expression would change to
2(10)+4
20+4
so your answer would be 24

This is a ratio problem. If dry ing : water = 5 : 2, what is water when dry ing = 15?
The new ratio is 15 : water. How do we get from the first ratio to the new one? We multiply by 5. Meaning, we also need to multiply the 2 quarts of water by 5, giving us 10 quarts of water.
All you have to do is rotate the current dots, and bam.
