7. Solve the story problem. Bailey has collected 9 shells from the
Atlantic Ocean and 3 times as many
shells from the Gulf of Mexico. How
many shells does she have altogether?
shells

She has 36 shells

9+(9*3)

9+27

Please mark as brainliest. :)

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
