In the equation, 1/4n+5=51/2 what is n equal to?

N = 2

Step-by-step explanation:

5 1/2 - 5

= 1/2

1/2 divided by 1/4 = 2

N = 2

n = 82

Step-by-step explanation:

So what you have to do here is simplify the fraction 51/2 into a whole number with a decimal. 51/2 will be 25.5 in number form, so you can plug that in:

1/4n + 5 = 25.5

Then subtract 5 from both sides to get n's number by itself:

1/4n = 20.5

At this point, you would multiply the denominator of 1/4 to both sides, which would be 4. So do that now and you will see that:

n = 82

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
