This stuff is quite easy in reality. Here's a little example including your numbers.
by this point we are left with simplifying it. Since it's a double negative we get a positive. Thus x=1
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but I believe that you want to know the number of rides that Katie can take.
Based on the information in the question, we can form an equation. Let the number of rides that Katie can take be represented by x. Therefore,
12 + (1.25 × x) = 50
12 + 1.25x = 50
1.25x = 50 - 12
1.25x = 38
x = 38/1.25
x = 30.4
Therefore, Katie can take at most 30 rides.
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.
