Which equation can you use to find the value of x? 78°
3x
(x - 2)
78 = x - 2
3x + 78+ X-2
3x - 78
3x + 78 + x - 2180

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

one set of data has more variation than the other. hope this !

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.
