60 teeth = 50 revolutions
40 teeth = x revolutions
To figure this out, you can multiply 60 and 50 together to get 3000, and 40 and x to get 40x.
If you solve this equation, 40x = 3000,
x = 75
Hope this helped!
The Second gear will complete 75 revolutions.
Hope this helps. I tried using my past knowledge.
Greetings!
You can solve this with a simple equation:
Take the letter x to be the unknown number:
20 = 8+ (X + 5)
Then you can move the 8 + to the opposite side making it a negative 8:
20-8 = X + 5
12 = X + 5
Move the +5 over to the other side, making it a negative 5:
12 - 5 = x
7 = x
So the value of x is 7.
Hope this helps!

Step-by-step explanation:
Answer: Ted's pencil could be 8.6 cm.
Step-by- Step explanation:
Since we have given that
Length of Jan's pencil= 8.5 cm
According to the question, we know that Ted's pencil is longer.
So, it must be larger in value than 8.5 cm .
So, it can be any decimal number greater than 8.5 cm
Hence, Ted's pencil could be 8.6 cm.
