Answers are:

16.
-1 - (-4) = 3

17.
-1-1/3 - (-4) = 2-2/3

18.
2 - (-1) = 3

19.
3-1/2 - (-1) = 4-1/2


20.
3-1/2 - 2 .= 1-1/2

21.
3-1/2 - (-1-1/3) = 4-5/6

Step by step: I took one point and subtracted the second point to get the length of each segment. You could also look at the ruler and count from one point to the other.

Remember when you subtract a negative, the two negatives become a positive

A fish tank contains 18 goldfish and 22 guppies. If you randomly select 2 fish, what is the probability that they are both goldf
Mila [183]
The total number of fish available in the tank is (18 + 22) = 40. We want to randomly select 2 fish and come up with 2 goldfish. The probability for 1 goldfish to be taken out would be 18/40. Now, after drawing the first fish, the probability to get another goldfish would be 17/39. And the probability to draw 2 goldfish would be the product of both probabilities. P = (18/40)(17/39) = 51/260 Thus, the answer is <span>B.</span>
