Question

Twice a number (x) is less than 10

Answer 1

2X<10, 2 times a number is less than 10

Answer 2

Let

x-------> the number

we know that

Twice a number (x) is less than
`10`

so

`2x < 10\\\\ x < (10)/(2) \\\\x < 5`

the solution is the interval ------> (-∞,5)

therefore

the answer is

`x < 5`
