Answer:
Jada walked 
Elena walked 
Lin walked 
Step-by-step explanation:
Let
x----> total miles walked by Jada
y----> total miles walked by Elena
z----> total miles walked by Lin
we know that
-----> equation A
----->
------> equation B
------> equation C
Substitute equation C and equation B in equation A and solve for x




Find the value of y

Find the value of z

therefore
Jada walked 
Elena walked 
Lin walked

Step-by-step explanation:
Here is the complete question: You are making juice from concentrate. The directions on the packaging say to mix 1 can of juice with 3 cans of water to make orange juice. How many 12 fluid ounces cans of the concentrate are required to prepare 200 6-ounce servings of orange juice?
Given: Ratio to make juice with concentrate:water is 1:3.
As required we need to prepare 200 6 ounce serving of Orange juice.
∴ 
Let there be x ounce of concentrate and 3x ounce of water to make 1200 ounce of orange juice.
Now, 
∴ x= 300 ounce
Next, lets find out how many cans of 12 ounce is required.

∴ 25 cans is required to make 1200 ounce of orange juice.
Answer:
CD = 3.602019190339
Step-by-step explanation:
CD = DA - CA
DA = DB×Cos(29) = 18.7×cos(29) = 16.355388523507
BA = BA×cos(43) = 18.7×cos(43) = 13.676314220278
CA = BA÷tan(47) = 13.676314220278÷tan(47) = 12.753369333168
Then
CD = 16.355388523507 - 12.753369333168 = 3.602019190339
23/6 as a mixed fraction is 3(5/6)
