-2х+4=-1/3х-21<br>Как это решить пожалуйста помогите пожалуйста решить ​
Oxana [17]

Answer:

x=15

Step-by-step explanation:

The given equation is

-2x+4=-\frac{1}{3}x-21

Here the variable is x and the terms with the variable are -2x \;and\; -\frac{1}{3}x.

Keep all the terms having variable on one side and all the constants terms on the other side as

-2x+\frac{1}{3}x=-21 -4

Now, simplify the above equation to get the value of x as

-\frac{5}{3}x=-25 \\\\\Rightarrow \frac{5}{3}x=25 \\\\\Rightarrow x=\frac{25\times3}{5} \\\\\Rightarrow x=15  \\\\

In this way, the value of x is 15.

Debora [2.8K]
  • Answer:

<em>$29178.25</em>

  • Step-by-step explanation:

<em>x = p(1 - r)ⁿ</em>

<em>p = original price</em>

<em>r = 8.3% = 0.083</em>

<em>n = 5 years</em>

<em>x = $45000(1 - 0.083)⁵</em>

<em>= $45000ₓ0.917⁵</em>

<em>= $45000ₓ0.64840548256</em>

<em>= </em><em>$29178.25</em>

If the area of a park is exactly halfway between 2.4 and 2.5 acres what is the area of the park
Paul [167]
Get the distance between two acres.

2.5 - 2.4 = 0.1

Divide the diffence by 2
0.1 / 2 = 0.05 - Halfway between them.

Therefore, 0.05 must be taken from 2.5 acres. it must be added to 2.4 acres to get the exact area of the park.

2.5 - 0.05 = 2.45
2.4 + 0.04 = 2.45 acres

OR

Simply get the average of the two to get the area since it is exactly halfway between the two acres of land.

2.5 + 2.4 = 2.9 / 2 = 2.45 acres
