Rational Numbers
A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.

The number 8 is a rational number because it can be written as the fraction 8/1.
Likewise, 3/4 is a rational number because it can be written as a fraction.
Even a big, clunky fraction like 7,324,908/56,003,492 is rational, simply because it can be written as a fraction.
Every whole number is a rational number, because any whole number can be written as a fraction. For example, 4 can be written as 4/1, 65 can be written as 65/1, and 3,867 can be written as 3,867/1.

the five members of the traynor family each buy train tickets during the train ride each family member buys a box one for $6.50
NeX [460]

Answer:

  $43.20

Step-by-step explanation:

If each family member buys one ticket and one lunch, then for ticket price t we have the total expenditure as ...

  5(t +6.50) = 248.50

  t +6.50 = 49.70 . . . . . divide by 5

  t = 43.20 . . . . . . . . . . subtract 6.50

The price of each train ticket is $43.20.

E=I×R and P=E×I what is the formula that will solve for R when only E and I are known
blagie [28]

You wrote it there yourself, at the beginning of your question.

You wrote                             E       =  I  x  R

Divide each side by  ' I ' :    E / I  =  R

That's what you're asking for. ^

If n = 11 and p = 5 what is the value of the expression 18 - n - 2 + p
yan [13]

Answer:

10

Step-by-step explanation:

If n = 11 and p = 5, we can just substitute the values in for n and p in the equation 18 - n - 2 + p.


The new equation would be 18 - 11 - 2 + 5.

Using PEMDAS, we get the answer of 10.  

18 - 11 = 7

7 - 2 = 5

5 + 5 = 10


Hope this helps!
