Answer:
23
Step-by-step explanation:
Two numbers have an average of 17, with one of the numbers being 11.
Note that to solve average, you must:
1) Add all numbers
2) Divide by the amount of numbers there is
3) Get answer.
---------------------------------------------------------------------------------------------
Note that the equation looks like:
(x + 11)/2 = 17
Note: x = the number you are solving for.
----------------------------------------------------------------------------------------------
Note the equal sign. What you do to one side, you do to the other. First, multiply 2 to both sides
(x + 11)/2(2) = 17(2)
x + 11 = 17(2)
x + 11 = 34
---------------------------------------------------------------------------------------------
Isolate the x. Subtract 11 from both sides
x + 11 (-11) = 34 (-11)
x = 34 - 11
x = 23
---------------------------------------------------------------------------------------------
23 is your answer
