Answer:
23 Yards
Step-by-step explanation:
So for this question, we would have to start off with writing an equation: 19.71+0.23x=25 once we subtract 19.71 on both sides, the left over sum of money will be 5.29. Since we are dealing with BOTH Dollars and Cents, it should be remembered to use 23 CENTS instead of Dollars. = 23 so the finals answer is 23 yards.

Step-by-step explanation:
We can answer this question as follows.
First of all, we call:
t = number of treadmills
b = number of stationary bikes
The two conditions that we have can be translated into equations as follows:
- The gym has a total of 25 treadmills and stationary bikes:
- There are seven more stationary bikes than treadmills:
So the system of equations to solve is
We now solve it in the following way: first, we rewrite the second equation by bringing t on the left side,
Now we add the 1st equation to the 2nd equation:
And therefore,
So, there are 16 stationary bikes and 9 treadmills.
