Answer: 24
To calculate with long division when the divisor is a decimal, add zeroes in both the dividend and divisor. This means you get 360 ÷ 15.
From here, just do normal calculation and you get 24 as your answer.
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.

Answer:
Step-by-step explanation:
Answer:
You need four squares.
On the top left square, you put the number 20 over it, and the number 30 to its left. Put the number 600 in the square.
Next, the bottom left square. But the number 4 on the left side of the square, and put the number 80 in the square.
Now, the top right box. put the number 8 over it, and fill it with the number 240.
Last, fill the bottom right square with the number 32.
