Answer:
Step-by-step explanation:
Let l represent number of miles ran by Pierre each day.
We have been given that Pierre runs the same around a track each day 4 days a week. So number of laps ran is 4 days would be .
We are also told that he runs a total of 12 miles each week and it takes 8 laps of the track to equal a mile. So number of laps in 12 miles would be 8 times 12.
Now, we will equate total laps ran in 4 days by 8 times 12 as:
Therefore, we can use the equation to find how many laps Pierre runs each day.
Let us solve for l as:
Therefore, Pierre runs 24 laps each day.
X=212, y=88, n=50, L=212 hope this helps
Answer:
cycle=33 students, driven=132 students, walk=55 students
Step-by-step explanation:
<h2>solution</h2><h2>60+15+x=100 to get the remaining percentage</h2><h2>x=25</h2><h2>15÷100×220=33</h2><h2>60÷100×220=132</h2><h2>25÷100×220=55</h2>
Basically looking for the x value of intersection of the two equations. Setting them equal,
2^x + 12 = 15x + 35, which you will get x = 7. Graph it out to get a visual solution.
The number of birds after 7 years would be 140, for both species.
