Answer:
B) 1/5
Step-by-step explanation:
P(R then Y) = 3/6 · 2/5 = 6/30 or 1/5 simplified
M is Matt's sticker count, D is David's:
The equations:
The average sticker count has to be 120, so:
(M + D) / 2 = 120
Matt has twice as many as David:
M = 2D
Substitute for M in the average, so:
(2D + D) / 2 = 120
Solving you get:
3D = 240
D = 80 and 120 - 80 is 40, so Matt has to give him 40 stickers.
Hope this helps :)

vertex Is (-2,0)
Answer:
30x25/100
25%=7,5$
30+7,5$=37,5$
The original price was 37,5 because you had to first find out what was 25% in $ to then do the opposite of a sale since we are finding the original price so we have to add it to 30$ since 30$ was the price after the sale.
Hope this helps, have a good day!
