Answer:
70 -20x = 60 -15x
Step-by-step explanation:
The amount of money left on Josh's card is ...
70 -20x
The amount of money left on Jessica's card is ...
60 -15x
These amounts are the same when ...
70 -20x = 60 -15x
_____
<em>Additional comment</em>
The solution to this equation is ...
10 = 5x ⇒ x = 2 . . same amount after purchase of 2 pizzas
<em>2 solutions</em>
<em>X= 16</em>
<em>X=49</em>
Step-by-step explanation:
<em>original equation</em>
<em>x-11√x+28 = 0</em>
<em> Isolate</em>
<em> -11√x = -x-28+0</em>
<em> Tidy up</em>
<em> 11√x = x+28</em>
<em> Raise both sides to the second power</em>
<em> (11√x)2 = (x+28)2</em>
<em>After squaring</em>
<em> 121x = x2+56x+784</em>
<em> Plug in 49 for x </em>
<em> 11√(49) = (49)+28</em>
<em>Simplify</em>
<em> 11√49 = 77</em>
<em> Solution checks !!</em>
<em> Solution is:</em>
x = 49
<em>Plug in 16 for x </em>
<em> 11√(16) = (16)+28</em>
<em>Simplify</em>
<em> 11√16 = 44</em>
<em> Solution checks !!</em>
<em> Solution is:</em>
x = 16

answer: D, Paying women as much as men is harmful to families and to society,
explanation : The letter argues that it is not the role of the government to "dictate to businesses what they should pay" and said "traditionally, men have earned more than women in the workplace because they are considered the primary breadwinners for families.
Answer:
75
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle:
3x + 2 + 55 = 13x - 3 add like terms
3x + 57 = 13x - 3 export like terms to the same side
57 + 3 = 13x - 3x
60 = 10x divide both sides by 10
6 = x to find angle FAB replace x with 6
13*6 - 3 = 75
