10/7 = 5w
solve for W

w = 0.29

Step-by-step explanation:

Given 10/7 = 5w

Find w?

Cross multiply to make it a linear equation.

We have 10 = 7 x 5w

10 = 35w

Now divide both sides by 35 to get w

10/35 = 35w/35

0.29 = w

Therefore w = 0.29

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.
