please answer me fast .​

Answer 1

let,the first number be x

and another be 2x

now,

120=x+2x

120=3x

x=120

30

×=40

therefore,the answer is 40

Answer 2

Step-by-step explanation:

4. Let the first multiple be x

second multiple=x+9

Third multiple =x+18

A/Q

x+x+9+x+18=270

3x+27=270

3x=270-27

3x=243

x=243/3

x=81

First consecutive multiple = 81

Second consecutive multiple = 81 + 9=90

Third consecutive multiple =81+18=99

5. Let the first number be x

Second number =2x

Sum of first number and Second number = 120

A/Q

x+2x=120

3x=120

x=120/3

x=40

First number =40

Second number = 2×40 = 80
