Question

One number is 8 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is ​1090, find the numbers.

Answer 1

Number one: x

Number two:8x

Number three: x+ 100

They added together equal to 1090:

x + 8x + x+ 100 = 1090

10x= 1090-100

10x=990

x=99

Number one: 99

Number two: 792

Number three: 199

Sum: 1090
