Can u solve it?<br> Find x,y,v and u.
ikadub [295]

Explanation:

Basically, you can do it in many ways. But just, in my opinion, exactly linear algebra was made for such cases.

the optimal way is to do it with Cramer's rule.

First, find the determinant and then find the determinant x, y, v, u.

Afterward, simply divide the determinant of variables by the usual determinant.

eg. \frac{Dx_{} }{D} and etc.

I think that is the best way to solve it without a hustle of myriad of calculations reducing it to row echelon form and solving with Gaussian elimination.

mojhsa [17]

Answer:

53.2 gallons

Last week 40 fifth graders went on a field trip to the science museum.
Artist 52 [7]
PART ONE:
To put this information into a fraction you write part over whole:
 8/40

To change this into a decimal you have to plug in 8÷40 into your calculator:
0.2

PART TWO:
After you subtract 8 from 40, there are 32 fifth graders left.
The fraction will look like this:
32/40

To change this into a decimal you have to plug in 32÷40 into your calculator:
0.8

I hope this was helpful!
