Jorge is playing a computer math game. in round 1 he lost 3.8 points, round 2 he lost another 6.7 points, and in round 3 he gained 5.2 points. what is the overall change in jorge's score after three rounds?

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.

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
