If a figure has four sides, it is a quadrilateral. what is the contrapositive of this statement? a. if a figure is a quadrilateral, it does not have four sides.
b. if a figure does not have four sides, it is a quadrilateral.
c. if a figure is not a quadrilateral, it does not have four sides.
d. if a figure has four sides, it is not a quadrilateral.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
