Write an equation that requires at least three steps to solve and whose solution is x=3.5

(2x)^2 + 1 = 50

Step-by-step explanation:

x = 3.5

2x = 7 (1 step)

(2x)^2 = 49 (2 steps)

(2x)^2 + 1 = 50 ( 3 steps)

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.
