Directions: place the parentheses in the expression so that it equals the given value. 12•2+2^3; value: 120 7^2+1-5•3; value: 135 • = multiply ^expoint

12 • (2 + 2³) = 12 • (2 + 8) = 12 • 10 = 120

(7² + 1 - 5) • 3 = (49 + 1 - 5) • 3 = (50 - 5) • 3 = 45 • 3 =135

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.
