Answer:
[tex]+4\frac{1}{4}[/tex] meters
Step-by-step explanation:
Let's take climbing down as "negative" and climbing up as "positive". Now, we can simply use the numbers and signs to find the change in elevation.
- [tex]2\frac{1}{2}[/tex] meters down means [tex]-2\frac{1}{2}[/tex]
- [tex]6\frac{3}{4}[/tex]meters up means [tex]+6\frac{3}{4}[/tex]
So, now we have: [tex]-2\frac{1}{2}+6\frac{3}{4}\\=-\frac{5}{2}+\frac{27}{4}\\=\frac{-5(2)+27}{4}\\=\frac{-10+27}{4}\\=\frac{17}{4}=4\frac{1}{4}[/tex]
Eric's elevation changed [tex]4\frac{1}{4}[/tex] meters above. So after the 2 moves, he is up by [tex]4\frac{1}{4}[/tex] meters.
