Step-by-step explanation:
Normally 7 envelopes but on rare occasions, there may be more due to If the packages are filled with Envelopes. Also depending on if the 7 packages are boxes of envelopes, and in that case, 140 envelopes times 7, which would be 980 envelopes in the 7 packages. 140 * 7 = 980.
Answer: 
Step-by-step explanation:
<h3>
The missing question is: "What is the Functions formula A(t)=?"</h3><h2 />
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
According to the data given in the exercise, you know that:
-
represents the area to paint the Hiros' romm as a function of time.
- The rate he painted the room was 8 square meters per hour.
- The area left to paint after 3 hours was 28 m².
Therefore, based on this, you can idenfity that:
1. The slope of the line is:

2. One of the point on the line is:
So you must substitute the slope and the coordinates of that point into
and then solve for "b" in order to find its value:

Therefore, you can determine that the function
is:

Answer:
Step-by-step explanation:
subtract 8
-5b=-15
divide negative 5
b=3
19%. If the denominator is 100, then the numerator plus a percent symbol is the answer. Hope this helps!
