Answer: 120
You can do p/100 = is/of
40/100 = is/300
then multiply diagonally which is 40 and 300
divide by 100
or the easier way is you can multiply .4 and 300
Answer:
false
Step-by-step explanation:
![\left[\begin{array}{c}-4\end{array}\right] +\left[\begin{array}{c}7\end{array}\right] =\left[\begin{array}{c}3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D-4%5Cend%7Barray%7D%5Cright%5D%20%2B%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D7%5Cend%7Barray%7D%5Cright%5D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D3%5Cend%7Barray%7D%5Cright%5D)
Both of the matrices are 1 x 1 ("one by one"), so they can be added to produce a 1 x 1 matrix.
To add (or subtract) two matrices, they must be the same size.
(m x n) + (m x n) = (m x n)
m x n means a matrix has m rows and n columns. Dimensions are always named in that order: rows, then columns.
Answer:
infinite many solutions
Step-by-step explanation:
<u>As L.H.S = R.H.S, there are infinite many solutions</u>
3x+50=6x-10
subtract 3x
50=3x-10
add 10
60=3x
divide by 3
20=x
