0.4x - 5 = 0.08x + 3 srry I forgot the x

Mathematics
1 answer:
Semenov [28]3 years ago

Answer:

x= 25.

Step-by-step explanation:

To isolate "x", I first moved all terms containing x to the left side of the equation: 0.32x-5=3 (0.4-0.08=0.32). Then moved all terms not containing x to the right side of the equation: 0.32x=8. Finally, I divided 8 by 0.32 which equals 25. Thus, x=25. I hope this helped!

  • Distance Formula: \displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-6, -5)

Point (2, 0)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

  1. Substitute [DF]:                    \displaystyle d = \sqrt{(2+6)^2+(0+5)^2}
  2. Add:                                      \displaystyle d = \sqrt{(8)^2+(5)^2}
  3. Exponents:                           \displaystyle d = \sqrt{64+25}
  4. Add:                                      \displaystyle d = \sqrt{89}

Elimination Method<br> 2x-4y=12 -x+2y=-6
Readme [11.4K]

Answer:

The given system has INFINITE NUMBER OF SOLUTIONS.

Step-by-step explanation:

Here, the given system of equation is given as:

2 x - 4 y = 12   ...  (1)

- x + 2 y = -6   ......  (2)

Now, to use the ELIMINATION METHOD we either need to cancel out x coefficients or the y coefficient.

Now, to cancel out the x- coefficient in both the equations:

Multiply equation (2) with 2 and add with (1), we get:

2 x  - 2x + 4 y - 4 y = 12 - 12  

or, 0 = 0

Hence, the given system has INFINITE NUMBER OF SOLUTIONS.
