a. 1.15
b. 6.20 divided by 4 = 1.55
c. 5 divided by 4 = 1.25
d. 5.50 divided by 5 = 1.1
D is correct
Given Equation = two
hundred thirty four thousand one hundred sixty-four.
Show this in 2 different form:
First Form:
=> two hundred thirty four thousand one hundred sixty-four = 230 164
We converted the word form into numeral or algebraic form
Second Form
=> two hundred thirty four thousand one hundred sixty-four
=> 200 000 + 30 000 + 4 000 + 100 + 60 + 4
This form is called expanded form where we showed the expanded value of
the number.
Step-by-step explanation:
- 360_90_110=160
- 2a+3a=160
- a=32°
Add 10 to first equation and 7 to 2nd
5x-3y=10
x+y=7
multiply 2nd equation by 3 and add to first
5x-3y=10
<u>3x+3y=21 +</u>
8x+0y=31
8x=31
divide by 8
x=31/8
(x,y)
we can see that there is 1 answer with (31/8, somethng)
answer is A
The calculator function that puts the augmented matrix
![\left[\begin{array}{cc|c}2&4&8\\6&3&-3\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D2%264%268%5C%5C6%263%26-3%5Cend%7Barray%7D%5Cright%5D%20%20)
into reduced row-echelon form will give you an identity matrix in the left columns and the solution in the rightmost column:
![\left[\begin{array}{ccc}1&0&-2\\0&1&3\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%26-2%5C%5C0%261%263%5Cend%7Barray%7D%5Cright%5D%20%20)
This corresponds to the first selection.
