Question

The sum of three consecutive multiples of7 is777 .find the multiples

Answer 1

Step-by-step explanation:

let the three consecutive multiples be x,x+7,x+14.

Now,

x+x+7+x+14=777

3x+21=777

3x=777-21

3x=756

x=756/3

x=252

therefore,x=252

x+7=252+7=259

x+14=252+14=266

Hence the multiples are 252,259,266.

Answer 2

Answer:

252,259 and 266

Step-by-step explanation:

a,a+7 and a+14=777

a+a+7+a+14=777

3a+21=777

3a=777-21

3a=756

3a/3=756/3

a=252

a+7=252+7=259

a+14=252+14=266

ans=252,259 and 266
