If m = 35 cm and n = 37 cm, what is the length of l?

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

answer: f = 32.2m

step-by-step explanation: that is the answer

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.
