Answer:
1
Step-by-step explanation:
Well you could use the exponential identity that:
To determine:
Which means that it's equal to:
and since anything to the power of 0 (except 0) is equal to 1, then the value is 1.
But you can also just see that the numerator and denominator are the same exact value, and since dividing something by it self, results in 1, the answer must be 1, which is kind of a proof as to why h^0 = 1.

Answer:
Option A, C and D are correct choices.
Step-by-step explanation:
Let x be the number of rides that Tomas has been on so far. Each ride costs 5 tickets. This means that cost of x rides will be 5x.
We are told that Tomas bought 80 tickets for rides at an amusement park.
To find the number of of tickets that Tomas has left we will subtract cost of x rides from total number of tickets that Thomas bought.
We can represent this information in an expression as:
Now let us see which of our given choices in equivalent to our expression.
A.
Upon looking at option A we can see that it is same as our expression, therefore, option A is the correct choice.
B.
We can see that in this expression cost of x rides in being added instead of subtraction, therefore, option B is not a correct choice.
C.
Upon distributing 5 we will get,
Now this expression is same same as our expression, therefore, option C is the correct choice.
D.
This expression is also same as our expression as we can rearrange the terms in this expression as: , therefore, option D is a correct choice as well.
E.
Upon distributing 5 we will get,
We can see that in this expression cost of x rides in being added instead of subtraction, therefore, option E is not a correct choice.
