Subtract 3 from both sides
5x=5
Divide both sides by 5
x=1
For this case we must make a conversion taking into account that:
1 mile equals 5280 feet
1 hour equals 60 minutes
So, we have:
Answer:
The conversion results:
We have two slots A and B
Slot A has 4 choices (2,4,5,8)
Once we make a choice, we can't reuse it. So we have 3 choices left for slot B
Multiply out the values mentioned above to get: 4*3 = 12
Alternatively you can use the nPr formula to get
n P r = (n!)/(n-r)!
4 P 2 = (4!)/(4-2)!
4 P 2 = (4!)/(2!)
4 P 2 = (4*3*2*1)/(2*1)
4 P 2 = 24/2
4 P 2 = 12
yielding the same answer
So no matter which method you use, the final answer is 12
70/x = 100/50
cross multiply
100x = 3500
<span>divide both sides by 100 to get your answer. so your answer is 35%.got it^_^
