b (55 books/day) B =number of B , A=number of a then
A+B =14 ........ A=14-B
aA+bB =905
70(14-B) +55B =905
980-70B+55B=905
-15B=-75
B=-75/-15 =5
A=14-B=14-5=9
Elisa's Printing Company has 9 Model A printing pressesand 5 Model B printing presses.
Given that Elisha's printing company have two kinds of printing presses,
Model A = 70 books per day
Model B = 55 books per day
In total they have printing presses, which allows 905 books per day.
We need to find number of each of press,
Let's assume Elisa's Printing Company has x Model A printing presses and y Model B printing presses.
According to the given information, the total number of Model A printing presses (x) can print 70x books per day, and the total number of Model B printing presses (y) can print 55y books per day. Since the company owns 14 total printing presses, we can create the following equation:
x + y = 14 (Equation 1)
The total number of books printed per day is given as 905. So, we can set up another equation based on the printing capacities of each model:
70x + 55y = 905 (Equation 2)
Now, we can solve these equations simultaneously to find the values of x and y.
Multiplying Equation 1 by 70, we get:
70x + 70y = 980 (Equation 3)
Subtracting Equation 2 from Equation 3:
(70x + 70y) - (70x + 55y) = 980 - 905
Simplifying:
15y = 75
Dividing both sides by 15:
y = 5
Substituting the value of y in Equation 1:
x + 5 = 14
x = 14 - 5
x = 9
Therefore, Elisa's Printing Company has 9 Model A printing pressesand 5 Model B printing presses.

Answer:
4,443,000,000 or 4.443 * 10^9 km.
Step-by-step explanation:
Neptune's distance from the sun = 4.5 * 10^9
= 4,500,000,000 km.
The required difference is
4,500,000,000 - 57,000,000
= 4,443,000,000 or 4.443 * 10^9.
Final answer:
The difference in distance from the sun between Mercury and Neptune is approximately 4,443,000,000 kilometers.
Explanation:
To find the difference in distance between Mercury and Neptune from the sun, we first need to understand that these distances are given in kilometers (km). Mercury is roughly 57,000,000 km from the sun, and Neptune is approximately 4.5 x 10 to the 9th power km from the sun. The 9th power, or exponent, denotes how many times a number (in this case, 10) is used in a multiplication. Hence, Neptune's distance from the sun is 4.5 x 10^9 km, or 4,500,000,000 km. To get the difference, we subtract Mercury's distance from Neptune's i.e., 4,500,000,000 km - 57,000,000 km = 4,443,000,000 km. So, the difference in distance from the sun between Mercury and Neptune is approximately 4,443,000,000 km.
