2x + 3y = -17 is one equation in a coincidental system of two linear equations. the other equation is _ y = _ x – 102. find the other two variables for the second equations.

In a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

The multiplicative property of equality states that for real numbers a, b, c, and d, if a = b and c = d, then ac = bd. true false

Which of the following represents the length of a diagonal of this trapezoid?
