2y*3x+46
3x+46=2y
(3x+46)/2=y
3/2x+23=y
y=3/2x+23
Answer:
5.25
Step-by-step explanation:
15/10=1.5
9*1.5=13.5
13.5-3=10.5

Answer: Hello mate!
You have one $20 bill, two $10 bills, three $5 bills and four $1 bills in a bag.
This adds to a total of 10 bills in the bag, and you want to know the expected value if you took one at random.
The expected value is defined as ∑pₙxₙ
where pₙ is the probability for each event (in this case is the number of bills of a given price divided the number of bills in the bag) and xₙ is the value of the bill.
Then we can write the expected value as:
E = (1/10)*$20 + (2/10)*$10 + (3/10)*$5 + (4/10)*$1 = (1/10)( 20$ + 2*$10 + 3*$5 + 4*$1) = (1/10)*($59) = $5.90
The expected value is $5.90.
Answer:
Originally
The number of coins in the first box was 
The number of coins in the second box was 
Finally
The number of coins in the first box is 
The number of coins in the second box is 
Step-by-step explanation:
Let
x-----> number of coins in the first box originally
y-----> number of coins in the second box originally
we know that

-----> equation A
-----> equation B
substitute equation A in equation B






Find the value of x

therefore
