=================================================
Work Shown:
x = amount of time it takes Blake to do the job by himself
y = amount of time it takes Ned to do the job by himself
z = time it takes if they worked together
In this case,
x = 9 and y = 6
Use those values to find z.
Answer:
The answer is -27
Step-by-step explanation:
-16-6=-22
-22+-5=-27
The answer is no, because the first two equations are right but the third equation equals -16 instead of -15. So the answer is no (2,-2,4) is not the solution to all the system of equations.
The answer is A. After you square root both sides, you have to add 3 to both sides and then divide both sides by 4.
