Find the inverse of the matrices if they Exist. Use the algorithm introduced in the section. [1 0 -2 -3 1 4 2 -3 4]
KiRa [710]

Answer:

\frac{1}{2} \left[\begin{array}{ccc}16&6&2\\20&8&2\\7&3&1\end{array}\right]

Step-by-step explanation:

Given is a matrix 3x3 as

\left[\begin{array}{ccc}1&0&2\\-3&1&4\\2&-3&4\end{array}\right]

|A| =2 hence inverse exists.

Cofactors are 16   20   7

                        6     8    3

                         2     2    1

Hence inverse =

\frac{1}{2} \left[\begin{array}{ccc}16&6&2\\20&8&2\\7&3&1\end{array}\right]

suppose you have 192 marbles in groups of 15 marbles each. Find the number of groups of marbles. Write the quotient with the rem
Umnica [9.8K]
Suppose you have 192 marbles.
You want to group this marble into 15 groups.
What we need to do is simply divide the given numbers
=> 192 is our dividend and 15 is our divisor
=> 192 / 15
=> 12.8 , thus there are 12 groups with a remainder of 8.
Now, convert this into fraction
=> 12 is our quotient, 8 is our remainder to use as our numerator and 192 as our denominator.
thus the fraction value of this is :
=> 12 8/192

koban [17]

Answer:

chocolate bar - 1 (whole number)

Step-by-step explanation:

1 -   \frac{1}{3}   \\  >  \frac{3}{3}  -  \frac{1}{3}  =  \frac{2}{3}

\frac{2}{3}  -  \frac{3}{4}  \\  >  \frac{2 \times 4}{3 \times 4}  -  \frac{3 \times 3}{4 \times 3}  \\   \\  \\  >  \frac{8}{12}  -  \frac{9}{12}

so I switch it become

\frac{9}{12}  -  \frac{8}{12}  =  \frac{1}{12}
