Hmm... how do you solve this equation? I'm stuck

30 units

Step-by-step explanation:

8/6=6/NW

36=NW8

NW=4.5

4.5^2+6^2=OW^2

56.25=OW^2

OW=7.5

7.5+10+12.5=30

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.

your answer is

a.
