Answer:
1. L1 = 
2. O2 = 
Step-by-step explanation:
Given: x = 
1. To make L1 the subject of formula;
x = 
cross multiply to have;
L2 - L1 = xL1(O2 - O1)
collect like terms,
L2 = xL1(O2 - O1) + L1
factorize the right hand side;
L2 = L1[x(O2 - O1)]
L1 = 
2. To make O2 the subject of formula;
x = 
cross multiply to have;
L2 - L1 = xL1(O2 - O1)
open the bracket to have;
L2 - L1 = xL1O2 - xL1O1
⇒ xL1O2 = L2 - L1 + xL1O1
O2 = 
= 
Answer:
k = 102
Step-by-step explanation:
Inverse variation is represented as follows:
y = k/x
Find k by substituting 17 for y and 6 for x:
17 = k/6
Multiplying both sides by 6 results in k = 102
This one is easy all you have to do is subtract the 2.25 by the 15 to get 12.75.
