Answer 2

`3`

Explanation:

When evaluating an expression with `color(blue)"mixed operations"` there is a particular order that must be followed.

Follow the order as set out in the acronym PEMDAS

[Parenthesis (brackets), Exponents (powers), Multiplication, Division, Addition, Subtraction]

If the expression consists only of multiplication/division or

addition/subtraction, then evaluate from `color(blue)"left to right"`

`-48-:(-8)xx5-:10`

`"evaluating from left to right"`

`rArr6xx5-:10larr" first division"`

`=30-:10larr" multiplication"`

`=3larr" second division"`
