Answer:
Number of Model A press = 9 and Number of Model B press = 5
Step-by-step explanation:
Number of books Model A can print per day = 70
Number of books Model B can print per day = 55
Let x be the number of Model A press and y be that of Model B press.
Total number of printing presses = 14
x + y = 14 ----------------1
Total number of books printed per day = 905
70x + 55y = 905-------2
Putting y = 14 - x in equation 2, we get:
70x + 55(14 - x) = 905
15x = 135
x = 9
y = 14 - 9 = 5
Hence number of Model A press is 9 and that of Model B press is 5.

Statement:
"If two sides of a triangle are congruent, then the angles opposite of them are congruent"
Converse:
If two angles of a triangle are congruent, then the two sides opposite them are congruent.
The converse of the statement is true and can be proven true using a two-column proof. In fact it is a theorem.
