Answer:
41.5
23.5
Step-by-step explanation:
Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 65. In other words, x plus y equals 65 and can be written as equation A:
x + y = 65
The difference between x and y is -18. In other words, x minus y equals -18 and can be written as equation B:
x - y = -18
Now solve equation B for x to get the revised equation B:
x = -18 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 65
-18+y+y=65
-18 + 2y = 65
2y = 83
y = 41.5
Now we know y is 41.5. Which means that we can substitute y for 41.5 in equation A and solve for x:
x + y = 65
x + 41.5= 65
X = 23.5
DIfference : 23.5 - 41.5 = 18
Sum: 41.5 +23.5 = 65
Hence, The two number are 23.5 and 41.5

Y=(11/8)x+6
subtract the 8y to the right then add the 48 to the left then divide by 8
Answer:
Step-by-step explanation:
Another way of phrasing this question is this; if only two bills are selected without replacement, what is the probability that at one of the two bills will be a $10 bill:
P(One $10 bill) = P(picking a $10 bill first then another type) + (picking another
type then a $10 bill)
= 
2x+2+x=20
3x+2=20
3x+2-2=20-2
3x=18
18/3=6
So x=6
So the shorter one is 6ft and the longer piece is 14ft. (Additional work to help support answer more) 14+6=20 and 6*2+2=14.
The appropriate formula for the accumulated amount (A) for a given principal (P), interest rate (r), and time period (t) is ...
... A = P·e^(rt)
Filling in the given numbers and doing the arithmetic, we get
... A = $25,000·e^(.043·8) ≈ $35,264.46
