Answer:
61 yeas old
Step-by-step explanation:
180 is dividable by 3 evenly into 60. If you remove 1 from one of the 60's and add it to another 60, the order is now 59,60,61. So the oldest friend is 61 years old
20+16+18+14+9+20+16=113
113÷7=16.14285714
after rounded the answer would be 16.
hope that's correct.
