Answer:
30
Step-by-step explanation:
If you start at -2F and count all the way to 28F you can mark down every count to get your answer. Or subtract 28F by -2F.
Answer:
so if x = 0, x = 2, and x = 4
3(0) + 2 = 0 + 2 = 2, so when x = 0, y = 2
3(2) + 2 = 6 + 2 = 8, so when x = 2, y = 8
3(4) + 2 = 12 + 2 = 14, so when x = 4, y = 14
Commonsense you do math in your mind
Keep in mind the the word "percent" translates to "for each 100." 25% can be read as "25 for each 100," which has the fractional representation

and the decimal representation 0.25. All of these representations are just different ways of writing the same value.
Note too that the fraction

can be reduced to

, so what the question is really asking is: 1/4 of what number is 9?
Well, if we know that 1/4 of the number is 9, we can easily find how large the whole number is by finding all 4/4 of it (the <em>whole</em> number)<em /><em />, or 4 x 9, which multiplies out to
36.
