Ming drew a triangle. The sum of the angles of the triangle is 180º.

Veronika [31]

Answer: The second matrix

If we want to write a proper matrix to represent the given system of equations, we have to arrange it in order:

$a+b+c=180$

$2a-b+0c=0$

$4a+0b-c=-5$

After this, we can write the matrix with the coefficients of each equation:

$\left[\begin{array}{ccc|c}1&1&1&180\\2&-1&0&0\\4&0&-1&-5\end{array}\right]$

Being this, the matrix that represents the measure of each angle in Ming's triangle

Natalie picked 135 berries in 15 minutes. If she continues picking at that rate, how long will it take her to pick 486 berries?

nikklg [1K]

We can use proportion to solve it
$135 berries -------------15min$
$486 berrier --------------x$
Our x is equal to = $x= \frac{486*15}{135} =54$ min
Its our result
