The resulting matrix of the row operation is given as follows:
![R = \left[\begin{array}{ccc}7&4.5&-6\\-6&-3&12\end{array}\right]](https://tex.z-dn.net/?f=R%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D7%264.5%26-6%5C%5C-6%26-3%2612%5Cend%7Barray%7D%5Cright%5D)
<h3>How to find the resulting matrix?</h3>
We apply the row operation on the original matrix, given as follows:
![A = \left[\begin{array}{ccc}4&3&0\\-6&-3&12\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%263%260%5C%5C-6%26-3%2612%5Cend%7Barray%7D%5Cright%5D)
The operation is given by:
That is, applying to each element, we have that:
Hence the resulting matrix is:

Answer: $210.75
Explanation: You multiply the price of the object by how many they buy.
So for the beams you calculate 3 x 45.25 and get 135.75. For the screws you multiply 6 x 12.50 and that equals 75. Then, for the total price you add the two together, so 135.75 + 75 = 210.75
Another way to do it is (3 x 45.25) + (6 x 12.50) = 210.75
Rocky because of the product rule which says that when multiplying two terms with the same base you add the exponents.
Answer:
here,
or, 3- 2c + 8 = 7
or, 11 - 2c = 7
or, -2c =7 - 11
or, -2c = -4
or, c = -4/ -2
or, c = 2#
hope this solution will be helpful for you!!
Answer: 109 nickels and 89 dimes
Step-by-step explanation: 198 minus 20 is 178 and 178 divided by 2 is 89 and 89 plus 20 is 109 so there are 109 nickels and 89 dimes
