Please help If 12a + 3b = 1 and 7b - 2a = 0, what is the average a and b?

1/4

Step-by-step explanation:

If you add the equations:

12a + 3b = 1

-2a + 7b = 0

(you get):

10a + 10b = 1 (divide by 10)

a + b = 1/2 (divide by 2 since average of two numbers is their sum divided by 2)

(a + b) / 2 = 1/4

1/20

is the answer yeah

1. 22

2. 1

3. 7

e2020 got it right

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
