Answer:
npr= n! /(n-r) !
nCr= =(n r) = n! /r!(n-r)1
Step-by-step explanation:
To find the slope of the graph you pick any piece of the line, and divide the vertical difference between its ends by the horizontal difference between its ends. If the graph is distance versus time then the slope represents the speed.
Answer:
5200 AED or 1404 USD
Step-by-step explanation:
You have 5000 in your account. If your money grows 4% each year, it's basically like multiplying by 1.04.
5000 * 1.04 = 5200
If the question is asking in USD, the conversion rate from AED to USD is
AED * 0.27 = USD
We can substitute
5200 AED* 0.27 = 1404 USD.
Answer: X = 7.
Step-by-step explanation: Move all terms that don't contain x to the right side and solve.
<em>I'll go step-by-step.</em>
<em></em>
1. Add 5 to <u>both</u> sides. 6x-(5+5)=37+5
2. Simplify 6x=42
3. Divide <u>both</u> sides by 6. 
4. Then simplify/Divide. 42 / 6 = 7
That's how you get 7!
X = 7
