Step-by-step explanation: first convert 4 1/2 into an improper fraction: 9/2
9/2 ÷ 3/4 = 9/2 · 4/3 (multiply fractions)
36/6
6
For this case we can express the rates as:
![\frac {2.40} {12} * \frac {dollars} {pen} = 0.2 \frac {dollars} {pen}](https://tex.z-dn.net/?f=%5Cfrac%20%7B2.40%7D%20%7B12%7D%20%2A%20%5Cfrac%20%7Bdollars%7D%20%7Bpen%7D%20%3D%200.2%20%5Cfrac%20%7Bdollars%7D%20%7Bpen%7D)
Option A
![\frac {12} {2.40} * \frac {pen} {dollars} = 5 \frac {pens} {dollar}](https://tex.z-dn.net/?f=%5Cfrac%20%7B12%7D%20%7B2.40%7D%20%2A%20%5Cfrac%20%7Bpen%7D%20%7Bdollars%7D%20%3D%205%20%5Cfrac%20%7Bpens%7D%20%7Bdollar%7D)
Option C
If the pen package contains 12, then the cost of the package is $2.40.

Answer:
All real numbers
Step-by-step explanation:
f(x) is a polynomial and is well defined for all real values of x
Domain is x ∈ R
Answer:
10x+ y
Step-by-step explanation:
The unit's digit is y and the ten's digit is x.
The ten's digit has a zero placed beside it .
So multiply x by 10 giving 10 x and then add the unit's digit .
This wil give 10x+ y
The number is 10 x + y
This can be elaborated through the use of numbers . Suppose we have unit's digit as 6 and the ten's digit as 5.
Multiply 10 by 5 and add 6
5*10 +6= 50+6= 56
