20+24-56 First use Distributive Property
44-56 Next do Addition
-12 Then Subtract
The answer would be 7/72 when you simplify it
Dave will have $12,728 after 15 years, if he has $8000 to invest for 15 years. He finds a bank that offers an interest rate of 3.1% compounded monthly.
Step-by-step explanation:
The given is,
Investment = $ 8000
No. of years = 15 years
Interest rate, i = 3.1 %
( compounded monthly )
Step:1
For for calculating future value with compound interest monthly,
.................(1)
Where,
A = Future amount
P = Initial investment
r = Rate of interest
n = Number of compounding in a year
t = Time period
Step:2
From given values,
P = $8000
r = 3.1%
t = 15 years
n = 12 ( for monthly)
Equation (1) becomes,





A = $ 12728.48
Result:
Dave will have $12,728 after 15 years, if he has $8000 to invest for 15 years. He finds a bank that offers an interest rate of 3.1% compounded monthly.
4x+y= x
Move all x term to left side
4x-x+y=0
Subtract 4x from 3x
3x+y=0
Move y term to right side
3x= -y
Divide both sides by 3
X= -y/3
Ok so if it's
4x+y= z solve for x
Move y to right side
4x= -y +z
Now divide both by 4 to get x alone
X= -y/4 + z/4
