Question

The product of what number and 7 is less than 49

Answer 1

x-\ number
x*7<49 | divide by 7
x<7

x from -infinity to 7

Answer 2

(-
`\infty,7)`

Explanation:

Let x be the number.

We have to find that the value of x for which product of x and 7 is less than 49.

Product of x and 7=7x

According to question

`7x<49`

Divide by 7 on both sides then we get

`(7x)/(7)<(49)/(7)`

`x<7`

Hence, the value of x belongs to (-
`\infty,7)` for which product of x and 7 is less than 49.

Answer: (-
`\infty,7)`
