olivia chooses the whole number she divides it by 4 then adds 8 she then divides this result by 2. her answer is 3.5. what number did she start with

-8

Step-by-step explanation:

just do the promble backwards

3.5 times 2 = 6

6-8=-2

-2 times 4 = -8

or solve for x

x/ 4 + 8 /2=3.5

correct answer:

i^31 = -i

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
