3 + c

Step-by-step explanation:

You need to have the sum of 3 coins and 'c' coins. This means that you have to add 3 and c. You don't know what c is, so you write the sum as:

3 + c

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

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
