Answer:
x = 66.5
x + 1 = 67.5
x + 2 = 68.5
x + 3 = 69.5
x + 4 = 70.5
x + 5 = 71.5
x + 6 = 72. 5
x + 7 = 73.5
x + 8 = 74.5
x + 9 = 84.5
Step-by-step explanation:
Given that :
Age of 10 friends are consecutive integers :
Let the ages be :
x, x+1, x+2, x+3, x+4, x+5, x+6, x+7, x+8, x+9
The sum of their ages = 710
Hence,
x + x+1 + x+2 + x+3 + x+4 + x+5 + x+6 + x+7 + x+8 + x+9 = 710
10x + 45 = 710
10x = 710 - 45
10x = 665
x = 665 / 10
x = 66.5
x + 1 = 67.5
x + 2 = 68.5
x + 3 = 69.5
x + 4 = 70.5
x + 5 = 71.5
x + 6 = 72. 5
x + 7 = 73.5
x + 8 = 74.5
x + 9 = 84.5

There is not a lot of work
Looking at it we can tell that 3 will go into 3 one time, and 3 will go into 9 three times because:
1 x 3 = 3
3 x 3 = 9
