Well, you already know how much she stuff per hour, but you still need to find out how much per minute. And in one hour, there are 60 minutes.
So you divide the amount in an hour by 60 minutes, meaning you divide : 228 ÷ 60 = ?
And once divided, you get 3.8. So that would mean that she stuffs 3.8 envelopes per one minute, so that means nearly 4, but since you aren't asked to round, I'd say to just go for the average rate, which is 3.8
5/2+2/3+n=1/6
5/2=15/6
2/3=4/6
15/6+4/6+n=1/6
19/6+n=1/6
n=1/6-19/6
n=-18/6
n=-3
So, your answer is -3

Step-by-step explanation:
Answer:
x = 0.666(Repeating)
Step-by-step explanation:
4x+1=5
Subtract 1 from both sides
4x=6
Divide both sides by 4
x = 0.666(Repeating)
Given:
M=(x1, y1)=(-2,-1),
N=(x2, y2)=(3,1),
M'=(x3, y3)= (0,2),
N'=(x4, y4)=(5, 4).
We can prove MN and M'N' have the same length by proving that the points form the vertices of a parallelogram.
For a parallelogram, opposite sides are equal
If we prove that the quadrilateral MNN'M' forms a parallellogram, then MN and M'N' will be the oppposite sides. So, we can prove that MN=M'N'.
To prove MNN'M' is a parallelogram, we have to first prove that two pairs of opposite sides are parallel,
Slope of MN= Slope of M'N'.
Slope of MM'=NN'.

Hence, slope of MN=Slope of M'N' and therefore, MN parallel to M'N'

Hence, slope of MM'=Slope of NN' nd therefore, MM' parallel to NN'.
Since both pairs of opposite sides of MNN'M' are parallel, MM'N'N is a parallelogram.
Since the opposite sides are of equal length in a parallelogram, it is proved that segments MN and M'N' have the same length.
