Question

the sum of 3 consecutive multiples of 15 is 270. Find the 3 multiples.​

Answer 1

Step-by-step explanation:

Let m be the smallest multiple. Then

Let m be the smallest multiple. Then 2*(m*15 + (m+1)*15 + (m+2)*15) = 270

Let m be the smallest multiple. Then 2*(m*15 + (m+1)*15 + (m+2)*15) = 270 15m + 15m + 15 + 15m + 30 = 135

Let m be the smallest multiple. Then 2*(m*15 + (m+1)*15 + (m+2)*15) = 270 15m + 15m + 15 + 15m + 30 = 135 Solve for m.

Answer 2

Answer:

270/15= 18

x+x+1+x+2=18

3x+3=18

3x=15

x=5

15*x=75

ans= 75,90,105
