Equation you are going to use is $A = P(1+ \frac{r}{n}) ^{nt}$ where A is the amount earned, P is the initial/principal amount, R is the rate, N is the number of periods the amount is compounded, and t is the time in years.

P = 18000, R = 66% or .66, N = monthly so 12, T = 44 years.

So plugging it we get $A = 18000( 1 + \frac{.66}{12})^{44*12}$ .

Type that into your calculator or an excel sheet for your answer. My calculator (a TI-36X Pro) gives me 3.40856195 $_{E}$ 16 which isn't a very practical answer for money calculations.

Solve the system of equations:<br> y = x-4<br> -2x + y = 18

Pie

Answer:

x = 7.3

Step-by-step explanation:

-2x + x-4 = 18

First, Combine Like Terms

-3x + (-4) = 18

Then, do Inverse Operations

-3x + -4 = 18

+ 4 +4

Cancel out the -4 +4 because it will equal zero and won't matter to the equation

-3x = 22

Do Inverse Operations again. In this case, you will divide.

-3x = 22

-3x/-3 = 22/-3

Cancel out the -3x/-3

22/-3 = x

7.3 = x

Which is a solution to the equation |10-5y|=20<br><br>y=2<br><br>y=4<br><br>y=6<br><br>y=10

Pavlova-9 [17]

Answer:

y=6

Step-by-step explanation:

|10-5y|=20

Since the absolute value is isolated, we can then separate the equations

For absolute values, there is a positive and negative when we remove the absolute values.

10-5y = 20 10-5y= -20

Subtract 10 from each side

10-10-5y = 20-10 10-10-5y= -20-10

-5y = 10 -5y = -30

Divide by -5

-5y/-5 =10/-5 -5y = -30/-5

y =-2 y =6

Indy has x erasers and y pencils. How many erasers and pencils does Indy have?

navik [9.2K]

X + y, because you do x + y and you can't simplify. Hope this helps!

Select all the values that cannot be probabilities a. 3/5b. 1c. -0.45d. 0.06e. 1.16f. 0g. 5/3h. √2

nikitadnepr [17]

Answer:

c,-0.45 ,

e. 1.16

g. 5/3

h. √2

Cannot be probability.

Step-by-step explanation:

Probability of any occurrence is always in the interval of 0 to 1. 0 and 1 inclusive.

0≤P(A)≤1

Any value outside this boundaries cannot be probability.

Therefore, -0.45,1.16,5/3 and √2 cannot be probability.
