Solve the equation for a. K = 4a + 9ab
Given equation is K = 4a + 9ab
Now we solve for 'a'. We need to get 'a' alone
We factor out 'a' from the right hand side
K = 4a + 9ab
K = a (4+9b)
Now we divide the equation both sides by 4+9b
So
Answer:
a = K/ 4+9b
Step-by-step explanation:
(D) is the answer
The answer to number 1 is 10. The answer to number 2 is 4-6, inclusive.
Well if you put -4 where x is.. you still do get the answer of 20.
So that is correct.
