Lets use a rule of three simple with direct proportion to solve:
20 boxes -----> 15 min
100 boxes ----> x
x = (100)(15)/20
x = 75
therefore it takes 75 mins to stack 100 boxes
If we use fractions to solve:
15/20 = x/100
and solve for x.
20/15 = 100/y
solve for y
(-2 + 3i + (5 - 2i)
= -2 + 5 + 3i - 2i
= 3 + i Answer
Im doin the same stuff and can’t figure it out
3 and 3 9 and 1 and there is more ways just see
A because it is just dividing by -3.
