Answer 1

Part 1

'x more than 7' written as an algebraic expression is:

= 7 + x

Part 2

Let the number be n

Therefore, 'a number less 35' written as an algebraic expression:

=n - 35

Part 3

Let the number be y

'5 times a number' written as an algebraic expression:

=5 x y = 5y

Part 4

`\text{One}-\text{third}=(1)/(3)`

Let the number be x.

`\begin{gathered} \text{One}-\text{third of a number}=(1)/(3)\text{ of x} \\ =(1)/(3)x \end{gathered}`

Part 5

`f\text{ divided by 10}=(f)/(10)`
