Solve: A = LW/2 for L
Answer:
I think L = W/2A
Step-by-step explanation:
Answer:
A: [tex]L=\frac{2A}{W}[/tex]
Step-by-step explanation:
[tex]A=\frac{LW}{2}[/tex]
[tex]\frac{LW}{2}=A[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:}2[/tex]
[tex]\frac{2LW}{2}=2A[/tex]
[tex]LW=2A[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}W;\quad \:W\ne \:0[/tex]
[tex]\frac{LW}{W}=\frac{2A}{W};\quad \:W\ne \:0[/tex]
[tex]Simplify[/tex]
[tex]L=\frac{2A}{W};\quad \:W\ne \:0[/tex]

Aggie is an australian exchange sudent in china, and she currenly has 14,000 yuan in her bank account. If the exchange rate changes from 1 australian dollar to 6.21 yuan to 1 australian dollar 6.37 chinese yuan, what happens to the value in australian dollars of the money in aggies bank account
Step-by-step explanation:
Amount in Aggie bank account = 14,000 yuan
Initial exchange rate:
1 Australian dollar = 6.21 yuan
Initial amount in Australian dollars will be;
x aus dollar = 14,000 yuan
cross multiply
6.21x = 14,000
x = 14,000/6.21
x = 2,254.428 australian dollars
If the exchange rate increases to 6.37 Chinese yuan, her new balance in Australian dollars will be y;
1 Australian dollar = 6.37 yuan
y Australian dollar = 14,000 yuan
cross multiply
6.37y = 14,000
x = 14,000/6.37
y = 2,197.80 Australian dollars
The change in her account balance due to increase in exchange rate is y-x
y-x = 2,197.80 - 2,254.428
y-x = -56.626 aus dollars
This negative values shows a decrease in her account balance by 56.626 aus dollars due to increase in the exchange rate.

The scale of dilation is the number that you multiply one side of the original triangle to get its corresponding side on the new triangle. In this case, it can be seen that AB corresponds to A'B', and so you divide A'B' by AB (6 divided by 4) to find that the scale factor is 6/4, or 3/2. If you do this with any of the other sides you will get the same answer.
Answer:
If you do this with any of the other sides you will get the same answer.
