Question

The sum of three consecutive multiples of 3 is equal to 6 more than four times the smallest multiple. What is the largest multiple ?.
a.)9
b.)12
c.)15
d.)18

Answer 1

Answer:  (a) 9

Step-by-step explanation:

1st multiple of 3: 1(3x)

2nd multiple of 3: 2(3x)

3rd multiple of 3: 3(3x)

Sum = 4(1st multiple of 3) + 6

1(3x) + 2(3x) + 3(3x) = 4(3x) + 6

 3x  +    6x  +    9x  =  12x  + 6

                        18x  = 12x + 6

                          6x =           6

                            x = 1

Largest (3rd) multiple is: 3(3x)

                                      = 9x

                                      = 9 · 1

                                      = 9
