The expression "7 x k x [?]" is equivalent to "7k[?]", and "-42 x k" is equal to "-42k".
To find the missing number, we need to solve for "[?]" in the equation "7k[?] = -42k".
Divide both sides of the equation by 7k to solve for "[?]":
7k[?]/(7k) = (-42k)/(7k)
[?] = -42/7
Simplifying the fraction -42/7 gives us -6.
Therefore, the missing number that completes the expression is C) -6.
what number completes the expression 7 x k x [?] so it is equivalent to -42 x k? A -7. B 7. C -6. D 6.
