Answer:
The required expression is [tex]\frac{42}{x}-8[/tex].
Step-by-step explanation:
Let the unknown number be x.
We need to find an expression for the given statement "8 less than the quotient of 42 and a number".
y = Quotient of 42 and a number = [tex]\frac{42}{x}[/tex].
8 less than the number y = y - 8
8 less than the quotient of 42 and a number is
[tex]\frac{42}{x}-8[/tex]
Therefore the expression for the given statement "8 less than the quotient of 42 and a number" is [tex]\frac{42}{x}-8[/tex].
