Answer: -3
Step-by-step explanation: 2x = -2 then you subtract 1 from that which is the same as adding negative one so -2 - 1 or -2 + -1 = -3
Answer:
Step-by-step explanation:
We need to check each u value to say if each one is correct...
8 
u - 27
when u = 33
8 33 - 27
8 6
and it's true!
So, 33 is solution
when u = 39
8 39 - 27
8 12
It isn't true. No solution!
When u = 31
8 31 - 27
8 4
It's true and it also is a solution.
when u = 35
8 35 - 27
8 8
it's true and it also is a solution.
Answer:
1: it is called a building cause it can still be improve or built on.
2: its an integer in a decimal formation.
3: cause each unit is apart from the other units even though it is 1 big building.
Step-by-step explanation:
The rotation of the gears in he mesh involves a circular motion
The second gear has 2 teeth
<h3>How to determine the number of teeth?</h3>
The given parameter can be represented using the following ratio:
Ratio = Teeth : Revolution
So, we have:
23 : 60 = Teeth : 5
Express as fraction
23/60 = Teeth/5
Multiply both sides by 5
Teeth = 5*23/60
Evaluate the product
Teeth = 2
Hence, the second gear has 2 teeth
