I'll won't be offend if u don't me with this

The average is found by adding the numbers and dividing by 2.

Since the average is 17, the total of the two numbers must equal 17 x 2 = 34.

One number is given as 11, so subtract 11 from 34:

34 - 11 = 23

The other number is 23.

Too check: add 11 and 23 and then divide by 2:

11 + 23 = 34

34/2 = 17.

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

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
