-1/6 (answer)
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:
Total number of ways will be 20
Step-by-step explanation:
We have given three identical green shirts and three identical red shirts
So total number of shirts = 3+3 = 5
We have to distribute these shirts to 6 children so that each children got one shirt
Number of ways will be equal to ( Here we divide by 3!3! because three green shirts and 3 red shirts are identical )
1. A chess player moves a knight from the location (3,2) to (5,1) on a chessboard.This means that
(3,2)→(5,1).
the translation rule is
(x,y)→(x+2,y-1) or in words 2 units right and 1 unit down.
2. If the player moves the knight from (5, 1) to (6, 3), then the translation is
(5,1)→(6,3)
and the rule is
(x,y)→(x+1,y+2).
This is translation 1 unit right and 2 units up.
