Question

the sum of 3 consecutive multiples of 9 is 378. find the 3 multiples with steps too please​

Answer 1

Step-by-step explanation:

equation created -› 9x + 9(x+1) + 9(x+2)

solve the equation then you will get the value of x

now put the value and find the value of consecutive numbers

Answer 2

Let,

The first number be $x.$

And the second number be $x + 9$

And the third number be $x + 9 + 9 = x + 18$

$a/q x + x + 9 + x + 18 = 378$

$= 3x + 27 = 378$

$= 3x = 378 -27$

$= x = \frac{351}{3}$

$= x = 117$

_____________________________

So,

The first number $= 117$.

The second number $= 117 + 9 = 126$.

The third number $= 117 + 18 = 135$.

_____________________________

To check,

$117 + 126 + 135 = 378$.

_____________________________

Hence,

$117, 126$ and $135$ are the $3$ consecutive multiples of $9$ whose sum is 378.
