Hey there! I'm happy to help!
Let's set this up a system of equations where x represents the number of 10 dollar bills and y represents the number of 20 dollar bills.
10x+20y=440
x=y+2
We see that x has a value of y+2, so we can replace the x in the first equation with y+2 so we can solve for y.
10(y+2)+20y=440
We use distributive property to undo the parentheses.
10y+20+20y=440
We combine like terms.
30y+20=440
We subtract 20 from both sides.
30y=420
y=14
Since there are 2 more $10 bills, there would be 16 of those.
Therefore, there are 16 $10 bills and 14 $20 bills.
Have a wonderful day! :D

Answer:
Step-by-step explanation:
Given that in the game Scrabble, there are a total of 100 tiles. Of the 100 tiles, 42 tiles have the vowels A, E, I, O, and U printed on them, 56 tiles have the consonants printed on them, and 2 tiles are left blank.
a. If tiles are selected at random, the probability that the first tile drawn from the pile of 100 tiles is a vowel = 
b. If tiles drawn are not replaced, the probability that the first two tiles selected are both vowels =
c. Event A is drawing a vowel, event B is drawing a consonant, and event C is drawing a blank tile. A1 means a vowel is drawn on the first selection, B2 means a consonant is drawn on the second selection, and C2 means a blank tile is drawn on the second selection. Tiles are selected at random and without replacement.
i. Find P(A1 and B2).
=
ii. Find P(A1 and c2).
=
iii. Find P(A1 and A2).=
Hello!
First you have to find what percent like action movies with the data you have
You add all the numbers up
80 + 160 + 200 + 360 = 800
Now you divide the amount that like action by the total amount of people that answered
160 / 800 = 0.2
Now you multiply this by 3200 to see how many would say action
3200 * 0.2 = 640
The answer is 640
Hope this helps!
