The equation that matches the given situation is
. So, after two moves, Eric's elevation changed
meters above.
We know that in mathematics, subtraction means removing something from a group or a number of things. What is left in the group gets smaller when we subtract. The minuend is the first element we use. The subtrahend is the part that is being removed. The difference is the portion that remains after subtraction.
Assume that "negative" means climbing down and "positive" means climbing up. We must locate the elevation change in this area.
Given that Eric climbed straight down
meters. So we can write
.
Again Eric climbed straight up
meters. So, we can write
.
Then the change = ![-2\frac{1}{2}+6\frac{3}{4}](https://tex.z-dn.net/?f=-2%5Cfrac%7B1%7D%7B2%7D%2B6%5Cfrac%7B3%7D%7B4%7D)
=![-\frac{(2*2+1)}{2}+\frac{6*4+3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B%282%2A2%2B1%29%7D%7B2%7D%2B%5Cfrac%7B6%2A4%2B3%7D%7B4%7D)
=![-\frac{5}{2} +\frac{27}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B5%7D%7B2%7D%20%2B%5Cfrac%7B27%7D%7B4%7D)
=![\frac{-(5*2)+27}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B-%285%2A2%29%2B27%7D%7B4%7D)
=![\frac{-10+27}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B-10%2B27%7D%7B4%7D)
=![\frac{17}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B4%7D)
=![\frac{4*4+1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B4%2A4%2B1%7D%7B4%7D)
=![4\frac{1}{4}](https://tex.z-dn.net/?f=4%5Cfrac%7B1%7D%7B4%7D)
Therefore, the equation that matches the given situation is
. So, after two moves, Eric's elevation changed
meters above.

2.D
Step-by-step explanation:
x = $80 profit made if sold all carrots.
y = $120 if all tomatoes are sold.
Answer:
10^2+2×2b×10+2b^2 = 100+40b+2b^2
So if you think about it, this problem isn't that hard. So say it's 12:59, the total sum of those digits would be 71. If it was 1:11, then the sum would be 3. If it was 3:47, the sum would be 50. So now, you have to find the time where it would be the least possible sum. that time would be 1:00 because 1+0+0=1
