Answer:
= 5 ( 12d + 23f )
Step-by-step explanation:
-2(5d-9f)+7f-10(-9f-7d
Open parenthesis
= -10d + 18f + 7f + 90f + 70d
Collect like terms
= -10d + 70d + 18f + 7f + 90f
= 60d + 115f
Factorise
= 5 ( 12d + 23f )
Therefore,
-2(5d-9f)+7f-10(-9f-7d) in its simplest form is 5 ( 12d + 23f )
Well you can just keep adding 55 =1hr until you get to 400 the same with 45

Answer: 320 boys
Step-by-step explanation: you would first take the total number (720) and divide it by the total number shown in the ratio (5+4=9)
720/9= 80
You would then take 80 and multiply it by 4 because that is the number representing the boys
80*4= 320
<span>If A file that is 256 megabytes is being downloaded and the download is 18.6% complete, then you just need to multiply the 256 megabytes with 18.6%
The calculation would be: 256 megabytes x 0,186= 47.616 megabytes.
If you round up the answer to nearest tenth it will be 47.6 megabytes</span>
