Answer:
Step-by-step explanation:
we have the following system of equations:
the substitution method requires that we take one of the variables of one equation, and substitute that value in the other equation.
in this case taking advantage of the fact that in the first equation the value of is already cleared, we substitute it in the second equation:
and then we solve for x:
and since x=0 substituting this into the first equation of the system to find the value of :
the answer is and

Step 2:
The details of the solution are as follows:
Step-by-step explanation:
Given :
At the state fair, admission at the gate is $9.
In addition, the cost of each ride is $3.
Suppose that Sam will go on x rides.
Then, cost of x rides ( in dollars) = Cost per ride x Number of rides
=3x
Total cost ( in dollars) : Admission fee + cost of x rides
= 9+3x
Sam wants the total number of dollars he spends on admission and rides to be at most t ( less than or equal to t )
CONCLUSION:
The final answer is:
Using the values and variables given, write an inequality describing this.
