Question

The quotient of five times a number 7 is no more than 10​

Answer 1

`x \ge3.5`

Explanation:

First, write the given in the form of a mathematical equation rather than words. I'll call the mystery number given in the question
`x`:

`(5*7)/(x) \leq 10`

Simplify:

`(35)/(x) \leq 10`

Solve for x:

`(35)/(x) *x\leq 10*x`

Simplify the fraction:

`35\leq 10x`

Divide by 10 to isolate x:

`(35)/(10) \leq x`

Flip the equation around to make it easier to read:

`x \ge (35)/(10)`

Simplify the fraction:

`x \ge (7)/(2)` or
`x \ge3.5`
