Mathematics

AleksandrR [38]3 years ago
3 0

Answer:

50kg

Step-by-step explanation:

25 kg of a 15% salt solution

25kg * 15%

25kg * 15/100 = 3.75 kg

3.75kg * 100/5

3.75 * 20 = 75

Mass of water in kg increased from 25kg to 75kg

75kg - 25kg = 50kg of water must be added.

W is the midpoint of VX. What is VX if VW=2x+5 and WX =4x-3
Novosadov [1.4K]

Answer:

<h2>VX = 26</h2>

Step-by-step explanation:

If W is the midpoint of VX then VW = WX. Therefore we have the equation:

2x + 5 = 4x - 3          <em>subtract 5 from both sides</em>

2x = 4x - 8       <em>subtract 4x from both sides</em>

-2x = -8        <em>divide both sides by (-2)</em>

x = 4

VX = VW + WX

VX = 2x + 5 + 4x - 3 = (2x + 4x) + (5 - 3) = 6x + 2

Put the value of x = 4 to 6x + 2:

VX = 6(4) + 2 = 24 + 2 = 26
