The sum of two numbers is 20. Their difference is 4. a. Write a system of equations that describe this situation
b. Solve by elimination to find the two numbers

The two numbers are 12 and 8

Step-by-step explanation:

Well this is pretty simple

We can just list out everything that Adds up to 20

1+19

2+18

3+17

4+16

5+15

6+14

7+13

8+12

9+11

10+10

Now just subtract each one until you get the one that equals to 4

Which is 12 and 8 in this case

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
