12 (x + 3) = 4 (2x + 9) +4x
is there a solution

there is no solution

Step-by-step explanation:

You would use distributive property first to get

12x+36 = 8x+36 + 4x

by combining like terms, you would get 12x+36 = 12x+36, meaning there is no solution to this equation

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
