Question

The sum of three consecutive multiples of 12is720find these multiples

Answer 1

Step-by-step explanation:

let the three consecutive multiples be x,x+12,x+24

Now,

x+x+12+x+24=720

3x+36=720

3x=720-36

3x=684

x=684/3

x=228

therefore,x=228

x+12=228+12=240

x+24=228+24=252

Hence the multiples are 228,240,252.

Answer 2

Answer:

228,240 and 252

Step-by-step explanation:

a,a+12 and a+24=720

a+a+12+24=720

3a+36=720

3a=720-36

3a=684

3a/3=684/3

a=228

a+12=240

a+24=252
