Answer: Longest tool life is at A-, B+ and C+, for an average predicted life of 552.5. From examination of the cube plot, we see that the low level of cutting speed and the high level of cutting angle gives good results regardless of metal hardness.
180 miles / 60miles per hour = 3 hours
9:00 am + 3 hours = 12:00pm
I think the slope (m) should be 16.
Answer:
If the variable is x, then they have x + 5 toffees altogether.
Step-by-step explanation:
There is no way to find x as it is an unknown number. "5 more than" simply means that you add 5 to x.
Since all the variables cancel out and the coefficient equal to eachother, this system of equation has
<u>infinitely many solutions!</u>
