5600
20000*.18= 3600
3600*4= 14400
14400- 20000= 5600
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.
Answer:
56kg

This question is pretty simple. First you want to divide 1120 by 20.
This will give you the answer of 56.
Answer:
cd^4
Step-by-step explanation:
cd^4/c^2d^8
you minus the exponents since it's division, so c^1-c^2=c^-1 and d^4-d^8= d^-4
1/c^-1d^-4 and you take the reciprocal to make it even cd^4
~I think that's right not sure though
