Hey there!!
The given equation :
... 5y ( 2y - 3 ) + ( 2y - 3 )
Let's write this as ...
... 5y ( 2y - 3 ) + 1 ( 2y - 3 )
Now, if we take ( 2y - 3 ) as a common term, we get...
... ( 5y + 1 ) ( 2y - 3 )
Hence, the correct answer would be option ( A )
Hope my answer helps!!
This should be quite easy to explain. So the first thing you want to do is multiply them. This isn't to hard if you know your times tables. Don't worry about the decimal till the end.
15.37
× 5
---------
76.85
15.37 times 5 is 76.85
Now on to the decimal. All you need to do is move it two times to the left. You see how it's in between the 5 and 3? The same goes for your answer. So it is 76.85
I hope this helped!! ^^ I can make this a little more easier to explain if you want me to just in case, ok?
I do not know the decimal, but I know the ratio. 7/50. I am not positive about my answer as a decimal but I think it is 7.50.
Answer/step-by-step explanation:
The 300/40 comes from the fact that ¾ of a 400 meter swim is 300 meters, and if you want to know how long he took to do that, you need to divide by the speed, 40 meters per minute (meters divided by meters per minute = minutes). Likewise with the 100/35—that’s the last 100 meters he swam, at the slightly slower speed.
Just to bring it all the way home, average speed is total distance divided by total time. that the total distance is 400 meters. You know the total time is 300/40 + 100/35. Average speed, then, is:
Average Speed: 
Round: 39 meters per minute
I think if wrong I'm sorry
