A negative and a negative equal a positive.
It would be 16m + 5m - 4
You would keep the -4 the same since it isn't being multiplied by anything.
I hope this helps!

1/4 th is 1/2 of a 1/2, so double the amount of fat the amount of fat in 1/2 a cup which would be 12 grams
Answer:
•0.5
Step-by-step explanation:
We'll assume the dilation was done at the origin point, so it was done evenly.
Since the k point went from (10,0) to (5,0), we know it was reduced... so the scale factor has to be below 1. A scale factor means the size wasn't changed and a dilation/scale factor larger than 1 means it was enlarged.
So, we take the new X-value (5) and divide it by the original X-value (10).
Scale factor = 5/10 = 1/2... so 0.5
Answer:
1350 to the nearest 100 is 1400
Answer:
A sample size of 385 should be used.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
That is z with a pvalue of 
, so Z = 1.96.
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
What sample size should be used (round the number up)
A sample of n should be used.
n is found when M = 5.
We have that 
Simplifying by 10
Rounding up
A sample size of 385 should be used.
