Finger [1]3 years ago
6 0

Answer:

2 sqrt(15)

Step-by-step explanation:

Using the secant tangent formula

(whole secant) x (external part) = (tangent)^2

(5+7) * 5 = x^2

12*5 = x^2

60 = x^2

Taking the square root

sqrt(60) = sqrt(x^2)

sqrt(4*15) = x

2 sqrt(15) =x

Solve equation using substitution method <br> 4(x-1)-3x=2
NikAS [45]

Answer:

x = 6

Step-by-step explanation:

Step 1: Write equation

4(x - 1) - 3x = 2

Step 2: Solve for <em>x</em>

  1. Distribute 4: 4x - 4 - 3x = 2
  2. Combine like terms: x - 4 = 2
  3. Add 4 to both sides: x = 6

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

4(6 - 1) - 3(6) = 2

4(5) - 18 = 2

20 - 18 = 2

2 = 2

Answer:

3,992.34 (I think)

Set an equation:

25000(1+.025)^6

and you should get an answer of 28992.33546

Then you should subtract the initial amount which is 25000 to find out how much interest is being paid.

So finally the answer would be 3,992.34.

If im not wrong that is :)

You have half a pound of chicken per person (1/2 lb / p) and since there are 3 people then 3 * (1/2 lb / p) will be needed 1.5 lb for every 3 people , but this amount must be in kilograms, so :

1.5lb*\frac{0.454kg}{lb}≅0.681kg.
