Partition the wholes into thirds rename fractions for 3 wholes use the number line

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

How many solutions does the nonlinear system of equations graphed below have?
