Answer:
3 friends are older than the average.
Step-by-step explanation:
First find the mean. The mean can be found adding all the numbers in the set together and dividing by the amount of numbers in the giving set:
(25 + 36 + 33 + 36 + 30)/5 = (160)/5 = 32
The average age is 32. There are 3 friends that are older than the average (33 , 36 , 36, respectfully).

Step-by-step explanation:
Answer: x=18
First cross multiply 4/3=24/x to get 4x= 3*24
Then simplify: 4x=72; x=18
Ok so if 5x + 24 equals 9x - 17, the we can write it like this:
5x + 24 = 9x - 17 ~~~ We have to get x on one side to find out what it is. So you can either subtract 5x from both sides or 9x from both sides. Imma subtract 5x from north sides which becomes:
5x - 5x + 24 = 9x - 5x - 17 Now simplify
24 = 4x - 17 Now isolate 4x. To do that we have to add 17 to both sides
24 + 17 = 4x - 17 + 17 Now simplify
41 = 4x Now we have to get x alone on one side. So divide 4 from both sides. Becomes
41/4 = 4x/4 Now simplify.
10.25 = x
