So for this, we will be doing a system of equations, one equation representing the sum and the other representing the difference. Let x = larger number and y = smaller number:
For this, I will be using the elimination method. With these equations, add them together to get 
. From here we can solve for x.
For this, just divide both sides by 2 and your first answer is 
Now that we have the value of x, substitute it into either equation to solve for y:
In short, <u>the two numbers are 12 and 7.</u>
Answer:

Step-by-step explanation:
Hey there champ! Basically you wanna divide 40 by 4, or the fraction 1/4 to get the number of kids absent which is 10. From here you subtract 10 from your og class size, 40 and get thirty! Have a great day :)
Answer:
10
Step-by-step explanation:
2 → $3500
? → $17500
? = 17500 x 2 / 3500 = 3500/3500 = 10
OR
3500 → 2
3500/2 = 1750
17500/1750 = 10
Therefore, whatever method you use, you will get 10 as an answer.
Answer:
(6,1)
Step-by-step explanation:
You know that to move up or down means to change the y- coordinate. So for this on you do 10-9. This is 1. So the new y- coordinate is 1.
