Explanation:

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

Follow the order as set out in the acronym PEMDAS.

Multiplication and division are of equal precedence and when they occur in the same expression are performed from left to right.

$- 48 \div 4 \times (- 5) - 17 \leftarrow division first$ $-48÷4xx(-5)-17larr" division first"$

$\Rightarrow - 12 \times (- 5) - 17 \leftarrow next multiplication$ $rArr-12xx(-5)-17larr" next multiplication"$

$\Rightarrow 60 - 17 \leftarrow finally subtraction$ $rArr60-17larr" finally subtraction"$

$= 43$ $=43$
