Answer:
12.5 minutes
Step-by-step explanation:
When working together,It takes two computers 10 minutes to send out an email
It takes the slower computer 50 minutes to send out an email
Let x represent the time taken by the faster computer to do the job in its own
Therefore, the time required by the faster computer can be calculated as follows
1/x + 1/50= 1/10
Collect the like terms
1/x= 1/10-1/50
1/x= 4/50
Cross multiply both sides
4 × x = 50×1
4x=50
Divide both sides by the coefficient of x which is 4
4x/4=50/4
x= 12.5
Hence the time taken by the faster computer to finish the job on its own is 12.5 minutes
If your turn 3/5 into 6/10 it becomes easier to turn into a decimal or a percentage.
3/5 = 0.60 = 60%

Answer:
-9.5116
Step-by-step explanation:
-1.58 * 6.02.
The easy way is to use your calculator.
To do it manually you can multiply -158 by 2, then by 10 and then by 600.
Add these 3 results.
This gives -95116.
Now you have 4 numbers after the decimal point in -1.58 and 6.02 so counting from the right in -95116 we locate the decimal point:
= -9.5116.
