5whole numbers are written in order, 4 , 7 , x , y, 11
the mean and median of the 5 numbers are the same , so what are the values of x and why and how did you work it out?
this is part of my maths homework , so need the answer as soon as possible , again!

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55
