You have a bag with 3 red marbles, 6 green marbles, 8 white marbles, and 7 black marbles. what is the probability of selecting a red marble? write your answer as a decimal rounded to the nearest hundredth.

.125

Step-by-step explanation:

You add 3+6+8+7=24. you're looking for red out of all the 24 marbles right? yes. so then you convert 3/24 into a decimal.

Hope this helps!

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
