Based on the calculations on this parallelogram, the correct equations are:

  1. n = 10
  2. CF = 59
  3. FE = 42

<h3>The properties of a parallelogram.</h3>

Based on the image of the parallelogram shown in the image attached below, we can logically deduce that the opposite sides of this parallelogram are all equal. Thus, we have:

Side DE = Side CF

6n - 1 = 5n + 9

6n - 5n = 9 + 1

n = 10.

From Side CF, we have:

CF = 5n + 9

CF = 5(10) + 9

CF = 59.

For the measure of side FE, we have

FE = 4n + 2

FE = 4(10) + 2

FE = 42.

Luna invested $8000 for 36 months at an interest rate of 4.8% per month. How much money will Luna have at the end of her investm
Degger [83]

Answer : $ 9, 152

Luna invested $8000 for 36 months at an interest rate of 4.8%

Let P = principal

T = time

r = rate

Using the simple interest,

\begin{gathered} I\text{ =}\frac{P\text{ x R x T}}{100} \\ P\text{ = \$8000} \\ r\text{ = 4.8\%} \\ t\text{ = 36 months} \\ 12\text{ months = 1 year} \\ 36\text{ months = x year} \\ \text{Cross multiply} \\ 12\cdot\text{ x = 1 x 36} \\ 12x\text{ = 36} \\ \text{Divide both sides by 12} \\ x\text{ = 36/12} \\ x\text{ = 3 years} \\ \text{Hence, t = 36 months = 3 years} \\ I\text{ = }\frac{8000\text{ x 3 x 4.8}}{100} \\ I\text{ = }\frac{115,\text{ 200}}{100} \\ I\text{ = \$1, 152} \end{gathered}

The total balance = Interest + principal

Balance = 1, 152 + 8000

Balance =$9, 152

The total money she will have at the end of the investment is $9, 152

How do I solve this do we use the multiple choice
belka [17]

Answer:

  (C)  4|5 -2x| > 68

Step-by-step explanation:

You can solve each of the inequalities to see if their solutions match the given numbers, or you can start with the given numbers and see what sort of inequality you end up with.

If you plot the given "solution" on a number line, you find that the numbers -6 and 11 are the same distance from x=2.5. That distance is 8.5 units. (One way to deterimine this is to average -6 and 11, then subtract that average from 11 to find the distance.

So, we can write an inequality describing values of x that are more than 8.5 units from 2.5:

  |x -2.5| > 8.5

and it will have the solution x < -6 or x > 11.

Multiplying this by 2, it can become ...

   |2x -5| > 17

Of course, since the absolute value function doesn't care whether its argument is positive or negative, we can also write this as ...

   |5 -2x| > 17

This tells you right away which answer choice is appropriate. Further confirmation can be had by multiplying this by 4:

  4|5 -2x| > 68 . . . . . . matches selection C

Question 14. When solving the equation -14 = 7x + 6 what will the next stage of your working be?
mr_godi [17]

Answer:

You would subtract 6 from each side.

Step-by-step explanation:

- 14 = 7x + 6

Subtract 6 from each side:

- 14 - 6 = 7x + 6 - 6

7x = - 20

Divide each side by 7:

7x ÷ 7 = - 20 ÷ 7

x = 2 and 6/7
