===>Factors of −48 with smaller absolute value negative:
smaller factor larger factor difference
-1 48 49
-2 24 26
-3 16 19
Add: -3 + 16 = 13
Therefore, the answer to this item is letter c.13.
Do 200 / 10 which equals 20 pgs/hr.
Then do 320 / 20 which equals 16 hours to read a 320 page book
Conclusion: It would take Jerry 16 hours to read a 320 page book
Answer:
Step-by-step explanation:
The given system is:
Since I prefer to use smaller numbers I'm going to divide both sides of the first equation by 3 and both sides of the equation equation by 6.
This gives me the system:
We could solve the first equation for and replace the second with that.
Let's do that.
Subtract on both sides:
So we are replacing the second in the second equation with which gives us:
Now recall the first equation we arranged so that was the subject. I'm referring to .
We can now find given that using the equation .
Let's do that.
with :
So the solution is (8,-1).
We can check this point by plugging it into both equations.
If both equations render true for that point, then we have verify the solution.
Let's try it.
with :
is a true equation so the "solution" looks promising still.
with :
is also true so the solution has been verified since both equations render true for that point.
