Answer 1

A

Answer 2

can you show me how you got that @popitree

Answer 3

let the num is m, so difference of a number and 8 is m-8.
now 5 times of it is 45

Answer 4

Let us break down the sentence: "Five times the difference of a number and 8 is 45."

"The difference of a number and 8" can be mathematically expressed as \(m-8\), where \(m\) is the "of a number" part.

"Five times..." indicates that we must multiply the above expression: \(5(m-8)\).

Finally, "... is 45." indicates we must set the above expression equal to \(45\), as follows: \(5(m-8)=45\).
