Answer:

\huge \boxed { \boxed{x =  \{6 , - 6 \}}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • absolute value
  • equation
  • PEMDAS
<h3>tips and formulas:</h3>
  • |a|=±a
<h3>let's solve:</h3>
  1. \sf divide \: bothe \: sides \: by \: 5 :  \\  \frac{ 5|2x| }{5}  =  \frac{60}{5}  \\  |2x|  = 12
  2. \sf seperate \: the \: equation \:in \: 2 \:parts :  \\  \begin{cases}2x = 12 \\   \: 2x =  - 12\end{cases}
  3. \sf \: di vide \: both \: sides \: by \: 2 : \\  \begin{cases}  \frac{2x}{2} =  \frac{12}{2}  \\   \:  \frac{2x}{2}  =   \frac{ - 12}{2} \end{cases} \\  \therefore  x =   \{6 , - 6 \}

ABC is isosceles.<br>m &lt; a = 3x + 40 and m &lt; c = x + 50<br>what is m &lt; a ??​
il63 [147K]

Answer:

  • 55°

Step-by-step explanation:

<u>It is assumed the angles A and C are congruent:</u>

  • 3x + 40 = x + 50
  • 3x - x = 50 - 40
  • 2x = 10
  • x = 5

m∠A = 3*5 + 40 = 55°

lisabon 2012 [21]
Let
x-->volume of white vinegar you need to add to the mixture (measured in cups)
<span>then
the amount of the pure vinegar in the mixture will be -----> (10*0.1 + x) cups
t</span>he volume of liquid will be ---------> 10 + x
the concentration equation is-------> [(10*0.1 + x)/(10+x)]=0.50<span>multiply both sides by (10+x) and then simplify

</span>(10*0.1 + x)=(10+x)*0.50-----------> 1+x=5+0.50x-------> 0.50x=4
x=8

the answer is 
<span>you need to add 8 of a cup of the pure vinegar to the mixture</span>
