(1) let there be x book and let the total cost be y dollars.
y=19.25x+40
y=16x+69.25
(2) 19.25x+40=16x+69.25
3.25x=29.25
x=9
9 silver book, 9 gold book.
(3) y=19.25x+40=19.25*9+40=213.25 dollars
both companies' total cost are 213.25 dollars.
Namely, how much is 1/4 of 1/2? well is just their product
Answer:
The speed of the object at time, t=4 is 
Step-by-step explanation:
The speed is calculated using the formula;
The distance covered by the object is given in terms of t, as
At time t=4, the distance covered by the object is;
The speed can now be calculated by substituting t=4 and distance 80 meters to obtain;
The large differences of the means of each group indicate that: B. the peppers with different weights aren't properly distributed between the two groups.
<h3>What is a mean?</h3>
A mean is also referred to as an average and it can be defined as a ratio of the sum of the total number in a data set to the frequency of the data set.
In this scenario, we can deduce that the large differences of the means of each group would indicate that the peppers with different weights aren't properly distributed between the two groups.

To estimate a derivative using values from a function, you simply have to take the slope (rate of change) of the line between the two adjacent values.
We use f(1.999) and f(2.001)
(8.012-7.988)/(2.001-1.999) = 12
