You don't have any choices here, but it's easy to determine what your matrix would look like by first writing the equations.  Oak trees is x and maple trees is y.  The first of our equations then is 3x + 4y = 380 and the second is 2x + 5y = 370.  In matrix form, that would be \left[\begin{array}{ccc}3&4\\2&5\end{array}\right]=  \left[\begin{array}{ccc}380\\370\\\end{array}\right]

Membership in the Volunteers Club increased by 15% from last year. If the number of members last year was m, complete a simplifi
ad-work [718]
For this case what you can do is the following rule of three:
 m ---> 100%
 x ----> 115%
 Clearing the value of x we have:
 x = (115/100) * (m)
 x = 1.15 * (m)
 Answer:
 a simplified expression to represent the number of members this year is:
 x = 1.15 * (m)
