What you must keep in mind is that there are 4 jeans in total, which represents 100%
 When she bought two jeans, we have the following information:
 If both of them are blue:
 50% of their jeans is blue now, that is:
 x = (50/100) * 4 = 2
 2 jeans are blue.
 This means that she did NOT have 2 blue jeans before.
 Thus:
 If they are not blue: 
 We have 4 jeans that are not blue.
 Then, 0% of her jeans is blue now
 answer:
 0% percentage of her jeans is blue now

  • [Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

<u>Step 1: Identify</u>

Leg <em>a</em> = <em>x</em>

Leg <em>b</em> = 5

Hypotenuse <em>c</em> = 8

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

  1. Substitute [PT]:                     x² + 5² = 8²
  2. Isolate <em>x</em> term:                       x² = 8² - 5²
  3. Exponents:                            x² = 64 - 25
  4. Subtract:                               x² = 39
  5. Isolate <em>x</em>:                               x = √39

-4( x – 4) = 8 – 4x <br><br> last one NEED help
Ilya [14]

16=8

first you need to get rid of the parenthesis by doing distributive property which gives you -4x+16=8-4x next you cancel equal terms which is -4x so then you get

16=8 btw the equation would be false

25%

Which inequality represents the situation ten less than a number is a minimum of 30?
Shkiper50 [21]

Answer:

x - 10 ≥ 30

Step-by-step explanation:

I'm 99.8% sure

It says 10 less than a number so that means subtract 10 from a number

Then it says minimum of 30 so that means the number has to be 30 or more so that's why I use the more than of equal to sign.

Hope this helps!
