The sum of two numbers is -18. If the first number is 10, which equation represents this situation, and what is the second number?

The equation that represents this solution is: 10+x= -18

The second number is -28.

Step-by-step explanation:

To solve for this, we first need to make an equation. We know that one of the numbers, the first one, is 10, but the second is unknown. Because of this, we will label the unknown number x. We also know that the -18 is the sum, so we know it will be behind the equal sign. Using this info, we can make the following equation.

10+x= -18

We did 10 because it was the first, added it with the unknown x, and it all equals -18. This would be your equation.

To find the answer, you need to solve the equation.

10+x= -18

First, since we are adding ten to both sides, subtract ten from both sides.

10-10+x= -18-10

Now, solve. Remember that subtracting a positive number is the same as adding a negative number.

x= -28

Now, check. Does 10+ -28 equal -18? Yes, so we are correct.

idk im srry

step-by-step explanation:

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
