The average of two numbers is 16. If one of the numbers is 11, what is the other number?

X = 21

Step-by-step explanation:

So we know one of the numbers is 11, so in order to get the average of 16, there needs to be a number that when added to 11 and divided by 2 gets you to 16. So let's put that into an equation. :)

16 =  (11 + x) /2

We have to get x alone so we need to multiply the 2 to the left side.

32 = 11 + x

Now, to get x alone we have to subtract 11 from both sides.

X = 21

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right

a) is $10.34

b) is 6 toppings
