Answer: Reduce (simplify) 195/100
Step-by-step explanation:
Answer:
43
Step-by-step explanation:
we know that ABC and CBD need to add up to 90 so we have
47+CBD=90
CBD=43
Let's consider an arbitrary 2x2 matrix as an example,
The columns of
are linearly independent if and only if the column vectors
are linearly independent.
This is the case if the only way we can make a linear combination of
reduce to the zero vector is to multiply the vectors by 0; that is,
only by letting
.
A more concrete example: suppose
Here,
and
. Notice that we can get the zero vector by taking
and
:
so the columns of
are not linearly independent, or linearly dependent.
1/4 goes into 2 2 /4
Means 2 2/4 divided by 1/4
Change 2 2 /4 to improper fraction. = (2*2 + 4)/4 = 10/4
10/4 ÷ 1/4
10/4 × 4/1
= 10
So it is 10.
