You could use the function:
f(x)=30+2x
100=30+2x
In which lets say he rode 3 rides. Plug in 3 for x.
100=30+2(3)
Then Multiply
100=30+6
Then combine 30 and 6 to get 36.
Then you can subtract 36 from 100 to get
$64 left over.
Answer:
x^2-18x+y^2+18y+137=0
express both x and y term in completed square form
(x-9)^2 -81+(y+9)^2-81+137=0
(x-9)^2+(y+9)^2-25=0
(x-9)^2+(y+9)^2=5^2
here the x coordinate of the centre is +9
y coordinate is -9(the negative value of the value associated with the x and y square brackets)
radius=5
we are asked to divide 5 over 536. Since the number we are diving by is larger than 5, the answer is a decimal number, the division can be done like this:

We need to add zeroes to the 5 until we get a number that is largest than 536, every time we do that we also add a zero to the answer, like this:
Now, if we multiply 536 by 9 we get 4824, we subtract that from 5000, like this:
Therefore, the answer is 0.009 with a remainder of 176
So,1 3/4 x 2 = 1 6/8
1 6/8 + 2 3/8 = 4 1/8
And now 4 1/8 + 5 7/8 = 10
I hope this helps

Answer:
Option C is the correct choice that is 
Step-by-step explanation:
As this is a multiple choice question we will reduce the options and work on it with the given points 
Note:We know that
where there is
sign associated with it have a straight line graph there is no breaking in the line.
And when there is simply
we have a dashed line when we plot it on a graph.
So option B and D are discarded.
Now one-by one we will put the values
to know which equation it satisfies.
If we put
then
.
So working with option A.

Plugging the values.

And we know that
must be equal to
so this is not the right answer.
We are left with only one choice that is C .
So option C is the correct option of the above inequality.
