It depends on the total number of marbles in the bag and the number of yellow marbles in the bag
Example of a real world problem:
Chris is starting a handmade card business. In the beginning, he starts off with 15 cards and makes 4 new cards every week.
The variable (x) would represent the number of weeks that passed.
Example 2:
Sam decides to start saving up money to buy a video game. She starts off with 15 dollars and gets an allowance of 4 dollars every day.
The variable (x) would represent the number of days that pass.
To come up with your own equation, most times, x represents a unit of time. The zero value (the number that isn’t being multiplied by a variable) in the equation always represents your starting value, and the coefficient of the variable represents how much of something is being gained or added after a duration of time.
I hope this helps!
10-(-4)
Change the subtracting sign to a adding sign and whatever is on the right side of the sign must turn into it's opposite so: 10+4= 14
14 is your answer!!!!!!!
Answer:
D, because in between -3 and -2 is -2 1/2, and absolute values are not negative, so the answer is 2 1/2, or D
False because for example using order of operation:
3-4*2= -5
But not using order of operation:
3-4*2=-1
