Answer:
C. 5 Red marbles
Step-by-step explanation:
If she started with 5 red marbles and had a probability of 1/5 of drawing a red marble, then there were 20 blue marbles, and 25 total marbles.
5/25 = 1/5
If she added 5 red marbles, she now would have 10 red marbles and still 20 blue marbles, giving her 30 total marbles in the bag.
10/30 = 1/3, so C is the right answer.
You can rule out other choices by repeating the above steps and substituting appropriate values
|b| + b^3; b = -2
|(-2)| + (-2)^3
|(-2)| + (-8)
- |(-2)| is the same as positive 2 since it is the absolute value.
2 + (-8)
<h3>-6 is your answer.</h3>

Answer:
800 pounds.
Step-by-step explanation:
We have been given that an object that weighs 24 pounds on Mercury weighs approximately 80 pounds on Earth. A rock weighs 240 pounds on Mercury. We are asked to find the weight of rock on Earth.
We will use proportions to solve our given problem as proportions state that the ratio between two proportional quantities is equal.

Upon substituting our given value, we will get:




Therefore, the weight of rock on Earth would be approximately 800 pounds.
