Question

The sum of three consecutive multiples of 11 is
330. Find the multiples.​

Answer 1

Respuesta:

90, 110, 121

Explicación paso a paso:

A multiple of 11 is: 11x

Three consecutive multiples of 11:   11x, 11(x+1), 11(x+2)

Sum:

11x + 11(x+1) + 11(x+2) = 330

11x + 11x + 11 + 11x + 22 =330

33x + 33 = 330

33x = 330-33

x = 227/33

x = 9

11*9= 90

11*10 = 110

11*11= 121
