Explain how to determine if the two expressions are equivalent using x=6 and x=2

d

step-by-step explanation:

i used the pitagoras theoreme

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.

answer: the answer is 110

2/3=10/15

1/5=3/15

10+3=13/15

2 13/15 is the answer
