What number completes the expression 7⋅k⋅[?] so it is equivalent to −42⋅k?(1 point)
To find the missing number that completes the expression 7⋅k⋅[?], we need to divide both sides of the equation -42⋅k = 7⋅k⋅[?] by 7⋅k.
This gives us -42/7 = [?]
Simplifying the left side of the equation, we have -6 = [?]
Therefore, the missing number that completes the expression 7⋅k⋅[?] so it is equivalent to −42⋅k is -6.
