Answer:
9x
Step-by-step explanation:
m=10x-x
10x means x in ten places so, it can be subtracted normally
m=9x
Answer: No. You cannot multiply the matrices in any order. A*B is not defined. Also, B*A is not defined.
------------------------------------------------------------------------
Explanation:
Matrix A has 1 row, and 4 columns.
Matrix B has 3 rows, and 4 columns
In order for A*B to be possible, A has to have the same number as columns as B has rows. In other words, the inner dimensions have to match up. The '4' in '1x4' needs to match up with the '3' in the '3x4'. This match doesn't happen.
The same story happens with B*A, just things have been flipped.
B has 3 rows, 4 columns
A has 1 row, 4 columns
The "4 columns" of B does not match with "1 row" of A.
1 Member = 1.5 Cup (Over the age of 10) for one day
7 Member (Over age of 10) = 1.5*7=10.5 cups in total.
Total of 10.5 per day.
In a week (Equivalent to 7 days):
10.5*7=73.5 Cups of beans in total
