1 m=1000cm, so 21m=2100cm
1min=60sec
so 21 m/min=2100сm/60sec=35cm/sec
1. You don't get the full "learning Process".
2. They are not <em><u>always </u></em>the best way/
These are my reasons hope they help! :D
(g-h) would be (2a-1)-(3a-3) given the information. This equals -a+2. Finally, we have to multiply this by -4 which gives us -4(-a+2)=4a-8
Explanation:
First, switch sides of an equation.
Then, you subtract by the 80 from both sides of an equation.
And finally, simplify and subtract the numbers.
Hope this helps!
Thank you!
Have a great day!
arithmetic,
To solve this problem you will need to know the difference between an arithmetic and a geometric.
An arithmetic is a sequence where a person is adding the same number over and over again so lets say you start with 1 and the common difference (the number being added each time) is 2, the sequence will look something like this 1, 3, 5, 7, 9 and so on.
A geometric sequence is when the same number is being multiplied over and over again. So lets say that the number we start with is 2 and you are multiplying by three every single time, so you would get a sequence looking like this 2, 6, 18, 54 and so on.
We can see in the sequence that the number that is being added over and over again is 3 so the first answer is arithmetic.
Now that we know that the sequence is arithmetic and the common difference is 3 we can plug that into the equation and we will see that 13.9 + 3 is 16.9
