Is the difference between a positive mixed number and a negative mixed number always, sometimes, or never positive?
pls give an example

If we consider that the positive mixed number is the first term and the negative mixed number is the second term and we consider "difference" to be subtractionthen the result is positive

For example

(3 + 1/2) -  [ -(1 + 1/2)] =

(3 +1/2) + (1 + 1/2) = 5   since subtracting a negative results in a positve

Butif we had the reverse order with the same operation, we would have

-(1 + 1/2) - (3 + 1/2)   and the result is - 5

HenceI would go with "sometimes"

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best

step-by-step explanation:

the answer is 8/21

hope this
