Which value of n makes the equation true?
6n - 2[4n + 7) + 4 = -2

-4

Step-by-step explanation:

6n -8n -14 +4 = -2

-2n = 8

n = -4

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.
