Answer:
15.
16. 10 ml of 20% saline and 40 ml of 10% saline
Step-by-step explanation:
A chemist takes x ml of 20% saline and y ml of 10% saline. In total, he takes
x + y ml that is 50 ml, so
There are 
ml of salt in x ml of 20% saline and 
ml of salt in 10% saline. There are 
ml of salt in 50 ml of 12% saline. Thus,
15. We get the system of two equations:
16. Solve this system. From the first equation:
Substitute it into the second equation:
Answer:
False

Answer:
Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.
Step-by-step explanation:
Given : 
, 
and 
To find : How much can Cam expect to earn if he sells all the corn produced on 1.5 acres?
Solution :
Substitute a=1.5,
Now, taking function
Substitute C=9750,
Now, taking function
Substitute a=1.5,
Therefore, Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.
Answer:
There is no solution for the given radical equation.
x = 225/16 is an extraneous solution.
Step-by-step explanation:
The given equation is
Add 3 to both sides of the equation
Squaring both sides
Divide both sides by 16
Substituting back the value of x in original equation to check the extraneous solution.
Since -18≠ 12. Hence, the value of x does not satisfy the equation.
Therefore, x = 225/16 is an extraneous solution.
