Answer:

y = 9 + 3x .

Step-by-step explanation:

Given : John's age is 9 more than three times Rick's age.

To find : Which expression represents this.

Solution : We have given John's age is 9 more than three times Rick's age.

Let the age Rick = x

According to question :

3 times the age of Rick = 3x .

Let the John age = y .

y = 9 + 3x . ( plus sign for more than ).

Therefore , y = 9 + 3x .

Answer:

168, a little of both

Step-by-step explanation:

Make 14 out of 50, 14/50 simplified its 7/25, multiply it by 600 and you get 168 its a little of both because half the info we were given its experimental since it is not theorized, what we're being given (the question) and what we gave is theorized since we didn't actually perform an experiment to get a real answer

How much should a family deposit at the end of every 6 months in order to have $4000 at the end of 3 years? The account pays 5.9

We are asked to determine the present value of an annuity that is paid at the end of each period. Therefore, we need to use the formula for present value ordinary, which is:

$PV_{ord}=C(\frac{1-(1+i)^{-kn}}{\frac{i}{k}})$

Where:

$\begin{gathered} C=\text{ payments each period} \\ i=\text{ interest rate} \\ n=\text{ number of periods} \\ k=\text{ number of times the interest is compounded} \end{gathered}$

Since the interest is compounded semi-annually this means that it is compounded 2 times a year, therefore, k = 2. Now we need to convert the interest rate into decimal form. To do that we will divide the interest rate by 100:

$\frac{5.9}{100}=0.059$

Now we substitute the values:

$PV_{ord}=4000(\frac{1-(1+0.059)^{-2(3)}}{\frac{0.059}{2}})$

Now we solve the operations, we get:

$PV_{\text{ord}}=39462.50$

Therefore, the present value must be $39462.50

The value of x is___.

monitta

Answer:

x = 3

Step-by-step explanation:

To find the value of x. We have to use Exterior Angle Theorem.

It is says "The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles of the triangle."

In the given figure,

45x = 25x + (57 + x)

Now let's find the value of x.

First we need to isolate the variable terms

45x - 25x = 57 + x

20x - x = 57

19x = 57

x = 57/19

x = 3

The value of x = 3.

Thank you.
