Hello!!!
So we are given some number, which we will call x for simplicity purposes. They tell us that number is divided by 4 so x/4, and then 17 is added, so we now have x/4+17 and they tell us this combination is equal to 25 so set what we have so far equal to 25. So we have finally x/4+17=25. Now we just solve for x!
x/4+17=25 first we subtract 17 from both sides leaving us with, x/4=8 so now See need to multiply by 4 on both sides to clear the fraction and get x alone. So we have now
x=8*4 so x=32
Now we can check our answer by putting our value of x into equation and make sure it’s true. So we have for our check,
32/4+17=25 and 32/4 is 8 so we have 8+17=25 which is 25=25 so our equation is true and our answer is correct!!
Hope this helps you understand the concept!! Any questions please just ask!! Thank you so much!!

Step-by-step explanation:
Answer: The maximum the average can be for all the guests at the birthday party is 2 minutes 57 seconds.
Step-by-step explanation:
Since the ratio of adults to children is 4:1, then it follows that:
4/5 of the people are children
1/5 of the people are adults
A weighed average of the times would give:
1 minute 25 seconds = 85 seconds [for 1/5 of the people (the adults)]
3 minutes 20 seconds = 200 seconds [for 4/5 of the people (the children)]
(85 x 1/5) + (200 x 4/5) = 177 seconds
Therefore, the maximum the average can be for all the guests at the birthday party is 2 mins 57 secs.
