ANSWER
Eva is correct because 13/2 + 3/2 = 8
There is no mistake. Dakota may have thought that there was a mistake because Eva simplified when she got the answer for 4x which is correct but Dakota may have thought that it was incorrect.
Since Upper K2 is already in meters, let's convert Batura Sar from feet to meters. We can do so by setting up the following conversion:
An equation with more than one variable is called a "literal Equation"
Answer:
3
Step-by-step explanation:
4.5 + 4.5 = 9
9/3 = 3
I have no idea what the "5-D Process" is. However:
2W = L-1
2W + 2L = 74
Add 1 to both sides of the first equation to isolate L.
2W+1 = L
Now substitute this value for L in the second equation:
2W + 2(2W + 1) = 74
2W + 4W + 2 = 74
6W + 2 = 74
6W = 72
W = 72/6 = 12
L = 2W + 1 [from above] = 2(12) + 1 = 24 + 1 = 25.
25 is one more than twice the width. 25 + 25 + 12 + 12 = 50 + 24 = 74
