Answer:

The answer to your question is: 2\sqrt{6} b + 2\sqrt{15} c

Step-by-step explanation:

     10\sqrt{6} b + 5 \sqrt{15} c - 8\sqrt{6} b - 3\sqrt{15} c

Simplify like terms

(10\sqrt{6} b - 8\sqrt{6} b) + (5\sqrt{15} c - 3\sqrt{15} c )

2\sqrt{6} b + 2\sqrt{15} c

Charlie runs at a speed of 3 yards per second . About how many miles per hour does Charlie run?
MrMuchimi
Ok so this can get tricky, it is basically just asking for you to perform many unit conversions. I'll try to simplify it for you here while still maintaining the explanation. If you have any questions about this process feel free to message me. 

3 yards = ____ miles (conversion factor is 1760 because there are 1760 yards in a mile) 

3/1760 = 0.017 miles,

Now we just need to convert seconds to hours. 

1 second is how many mins, then how many mins in an hour? 

360 seconds in an hour. 

Ok now we just need to combine these two pieces of info, 
0.017/360 = 4.72222 miles per hour. Thus 4.72 is the answer.

Your housing and fixed expenses are $702.38/month. What is your realized income for the month if your expenses account 30%
Ksenya-84 [330]
We are asked to solve for the monthly income given that 30% of it goes to your expenses.
Expenses per month = $702.38
Expenses percent from income = 30% = 0.3
Total income per month  = X

The solution is shown below:
$702.38 = 30% * X
X = $702.38 / 0.3
X = $2,341.27

The total income is $2,341.27.
