1) Answer: 113
3^3 + 2[64 - (3x7)]
27 + 2[64 - (3x7)]
27 + 2[64 - 21]
27 + 2[43]
27 + 86
= 113
3) Answer: (-1, 11)
Since the problem said that it was 11 points across the y-axis, you just have to replace the -12 with 11 because -12 is the y-value.
4) 5.5 quarts = 11 pints
1 quart is equal to 2 pints, so just double the amount of quarts.
5) 120 minutes (or 2 hours)
Set up a proportion and solve for the missing value. (24/x = 6/30)
6) 5 and 8
5 x 8 = 40
5 + 8 = 13
8) -8.95
1.3 + (-6) + (-4.25)
1.3 - 6 - 4.25
-4.7 - 4.25
= -8.95
Answer:
Not possible.
Step-by-step explanation:
Addition of Matrix A and Matrix B is possible only if the order of matrix A is same as the order of matrix B.
Order of a matrix with 
rows and 
columns is 
.
Here, matrix A is ![\left[\begin{array}{ccc}2&-4\\-4&10\\0&-8\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%26-4%5C%5C-4%2610%5C%5C0%26-8%5Cend%7Barray%7D%5Cright%5D)
Matrix B is ![\left[\begin{array}{ccc}0&-4&6\\2&-10&4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D0%26-4%266%5C%5C2%26-10%264%5Cend%7Barray%7D%5Cright%5D)
.
Multiplying a matrix by a constant doesn't change its order.
So, order of matrix A is 
as it has 3 rows and 2 columns.
The order of matrix 3B is 
as it has 2 rows and 3 columns.
Therefore, addition is not possible as the order is different.
