K=1/3
simplify each bracket, put all numbers on the left hand side, equal it to 0 and solve for k
Answer:
80 lemons
Step-by-step explanation:
Let x represent the amount of lemons that were on the tree.
We can use this to set up an equation:
![40\%x=32](https://tex.z-dn.net/?f=40%5C%25x%3D32)
Note that percentages can also be written as that number over 100.
![\frac{40}{100}x=32](https://tex.z-dn.net/?f=%5Cfrac%7B40%7D%7B100%7Dx%3D32)
Simplify the fraction.
![\frac{2}{5}x=32](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7Dx%3D32)
Multiply both sides by 5
![2x=160](https://tex.z-dn.net/?f=2x%3D160)
Divide both sides by 2
![x=80](https://tex.z-dn.net/?f=x%3D80)
There were 80 lemons on the tree before he picked the lemons.
A(-7,-4) B(-2,0)
√[(x'-x)^2+(y'-y)^2]
√(-2-(-7)^2+(0-(-4)^2
√(5^2)+(4^2)
√25+16
√41
the distance is approximately 6.4 units
