Answer:
Step-by-step explanation:
Add all the beads together to get your total amount of beads (This will be your denominator)
1+2+2+1=6 beads in total
You only want to focus on the amount of green beads. (Which is 2 and that will be you numerator)

Where is the angle? How can I solve this without the problem?
Answer:
your answer would be OA
Step-by-step explanation:
(2x - y)(4x2 + 2xy + y2) =
8x3 + 4x2y + 2xy2 - 4xy2 - 2xy2 - y3 (combine and simplify like terms)
= 8x3 - y3
Let's assume
number of shorts is x
we are given
People bought 2 times as many T-shirts as shorts
so, number of T-shirts is 2*x=2x
Dots sells T-shirts ($3) and shorts ($7)
so, total price of T-shirts 
so, total price of shorts 
now, we are given
total sales were $520
so,
total price of T-shirts+total price of shorts = total sales
we will get equation

now, we can solve for x


so,
number of shorts is 40
number of T-shirts is 2*40=80............Answer
