X=50
all four of a squares angles are 90°
90•3=270
270-20=250
250/5=50
x=50
Answer:
2.30 is going to be your anwer

Answer:

Step-by-step explanation:
(a/5) - (b/3) = (a/2) - (b/6)
+(B/3) + (b/3)
NOTE: use property of equality to isolate <em>b</em> from <em>a</em>
(a/5) = (b/3) + (a/2) - (b/6)
-(a/2) - (a/2)
NOTE: continue to use property of equality to isolate <em>a</em><em> </em>from <em>b</em>
(a/5) - (a/2) = (b/3) - (b/6)
60((a/5) - (a/2)) = ((b/3) - (b/6))60
NOTE: 60 is a common multiple of 5, 2, 3, and 6
12a - 30a = 20b - 10b
NOTE: combine alike terms
-17a = 10b
-17a/-17 = 10b/-17
NOTE: decide by -16 to find what a is equal to

Final answer
Answer:
A - $10
Step-by-step explanation:
The equation f(x) = 0.50x + 10 is in the form
y = mx + c where m is the gradient and c is the intercept.
The price of the entrance fee will be the intercept because that is when x is equal to 0, meaning it will be $10.
