As a sporting goods store,3/10 of all the items are baseball items and 1/3 of all the items are football items. what fraction of the total number of items in the store are baseball or football items?

Find a common denominator first... which would be 30

3/10×3= 9/30 baseball items

1/3×10= 10/30 football items

10/30+9/30= 19/30 total football and baseball items

19/30 doesn't simplify, so the answer is 19/30

Step-by-step explanation:

529 and 531

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
