2) The sum of three consecutive multiples of 6 is 162. Find the multiples.
Andru [333]

Answer:

48, 54 and 60

Step-by-step explanation:

Let the three multiples be 6x, 6(x+1) and 6(x+2) respectively.

6x+6(x+1)+6(x+2)=162

6x+6x+6+6x+12=162

18x=144

x=8

Therefore, the three multiples are 6(8), 6(8+1) and 6(8+2)

i.e. 48, 54 and 60
