To solve a kind of question like this and to have a better understanding while solving it. It is pertinent to list out the parameters given:
List of Items bought by Nicole:
If Nicole gave her mother the money $40 for babysitting, and:
Her mother paid back $5.26 out of it.
Then, the total amount of money Nicole's mother owed Nicole can be calculated by adding the items Nicole bought with the amount her mother paid her back, then we will subtract the total amount from the money Nicole gave her mother for babysitting.
Mathematically, we have:
= $(9.75 + 29.99 + 15+ 5.26) - $(40)
= $60 - $40
= $20
Therefore, we can conclude that the amount of Money Nicole's mother owed Nicole for babysitting is $20

To figure this out just add:
9.75 + 29.99 + 15 + 5.26 = $60 Since this is $20 more than Nicole gave her mom that means she made $20 baby sitting. There's your answer!
The probability of randomly picking out a red marble is 1/5
To determine the probability of randomly picking out a marble and it being red, we need to consider the total number of marbles and the number of red marbles.
Total marbles = 5 green + 3 blue + 2 red = 10 marbles
Red marbles = 2
So, we have
Probability = (Number of favorable outcomes) / (Total possible outcomes)
This gives
Probability = (Number of red marbles) / (Total marbles)
By subsituition
Probability = 2/10 = 1/5
Hence, the probability of randomly picking out a marble and it being red is 1/5

Answer:
1/5
Step-by-step explanation:
Since there are 2 red marbles and since there are a total of 10 marbles, the probability is 2/10. This simplifies to 1/5. So the probability of picking a red marble is 1/5.
Answer:
y=-x+5
Step-by-step explanation:
subtract the x from both sides to get y=-x+5.
