Answer:
24
Step-by-step explanation:
Cost of membership + game = 2.50x + 54
Cost of just games = 4.75x
The catch is, how do we make up the 54 dollars?
So equate the 2 costs
4.75x = 2.50x + 54 Subtract 2.50
4.75x - 2.50x = 54 Combine
2.25x = 54 Divide by 2.25
x = 54/2.25
x = 24
That means that 24 is the break even point.

Answer faster and plz and thank you
Because the angle is a straight angle, it means that the total of DEC and CEF would be 180º. (CEF + DEF = 180º) With this information we can make the equasion:
(11x - 12) + (2x + 10) = 180
first, to find x:
to simplify (11x - 12) + (2x + 10) = 180, you add the two equations:
13x - 2 = 180
13x = 182
x = 182/13
x = 14
Now, insert the x (which we found that is 14) to each equation.
DEC: (11 x 14 - 12)
= 154 - 12 = 142
m DEC is 142º.
CEF: (2 x 14 + 10)
=28 + 10 = 38
m CEF is 38º.
<em>check: (CEF + DEC = 180º)</em>
<em>38 + 142 = 180 </em>
therefore, the answers are correct :D
