3.78
All you need to do is plug in the numbers to your calculater, but since I'm guessing your in grade school, and they don't allow calculaters yet, you would need to understand that when two negatives multiply each other, they become positive, so you can just put
0.6
x 6.3
---------
and then just multiply as usual (ignore the decimals for now)
and then you would get 378.
Now, what you would do is because there is too decimal points in the two numbers you are multiplying, you put them into 378, making it 3.78.]
I'm sorry if it was confusing, I hope it helped!
a=-5/2
Step-by-step explanation:
-6a=-5-8a
-6a+8a=-5-8a+8a
2a=-5
a=-5/2
We can determine that the ratio is simplified by checking that the numbers in ratio can be divided with the same number, if it can be divided then it is not simplified for example 9:12 is the ratio and we can divide both numbers with 3 and then we get 3 : 4.
Now we cannot divide 3:4 further with any same number so this is simplified form.
Answer:
-2 is the slope
Step-by-step explanation:
To group an expression, means that the factors of the expression are to be separated in (), [] or {}.
An expression with a value of 80 is: ![2^2 \times ( [2 + 2] \times [3 + 2] )](https://tex.z-dn.net/?f=2%5E2%20%5Ctimes%20%28%20%5B2%20%2B%202%5D%20%5Ctimes%20%5B3%20%2B%202%5D%20%29)
The number is given as:
Factorize
Factorize 40
Express 
as an exponent
Express 20 as 4 x 5
Express 5 as 3 + 2
![80 = 2^2 \times ( 4 \times [3 + 2] )](https://tex.z-dn.net/?f=80%20%3D%202%5E2%20%5Ctimes%20%28%204%20%5Ctimes%20%5B3%20%2B%202%5D%20%29)
Express 4 as 2 + 2
![80 = 2^2 \times ( [2 + 2] \times [3 + 2] )](https://tex.z-dn.net/?f=80%20%3D%202%5E2%20%5Ctimes%20%28%20%5B2%20%2B%202%5D%20%5Ctimes%20%5B3%20%2B%202%5D%20%29)
Hence, the above expression has a numerical value of 80
