Answer:
11
Step-by-step explanation:
The mean is calculated as
mean = 
let the third number be x , then
= 15 ( multiply both sides by 3 to clear the fraction )
34 + x = 45 ( subtract 34 from both sides )

The answer is B
Have a good day!
When we solve for y, we want to isolate y by itself. To do so in this equation, we can divide both sides of the equation by 62...
y = 434/62 = 7
8x+6=62
8x=62-6
8x=56
X=56/8
X=7
The answer is 7. Hope this helps!
