Answer:

63.1 pounds

Step-by-step explanation:

1. Change the percentage into a decimal.

          12.5% ↔ .125

2. multiply the percentage as a decimal with 72.

           72x.125= 9              (this is the same as what is 12.5% of 72)

3. Subtract the number you just got from 72

              72-9= 63

(3xy)^2x^4y simplifying an expression
DerKrebs [107]

Answer:

36x^6y^3

Step-by-step explanation:

The problem needs application of law of indices

1. (xy)^m = x^my^m

This means common power for terms can be applied to each term individually.

x^a x^b = x^(a+b)\\

Separate power for the terms having  same base can be added together.

_______________________________________________________

we will be using these law of indices in the problem

(3xy)^2x^4y \\=> 3^2x^2y^2x^4y

applied the first rule of indices as mentioned above

3^2x^2y^2x^4y\\=>9*x^(2+4)4y^(2+1)\\=>9*4x^6y^3\\=>36x^6y^3

applied the second rule of indices as mentioned above

Thus, simplified form of (3xy)^2x^4y  is 36x^6y^3.

I believe it is X * 2 + 5 = Jim's total

Step-by-step explanation:

X is the amount of hours Kelly reads and multiplying X by 2 is how you find Tim's total. Then to find Jim's total you add 5 because that's how many more hours he reads than Tim.
