Answer:
$387.50
Step-by-step explanation:
You can get the answer 2 different ways. First you could take $275/2 = $137.50
Or
$275*0.50 = 137.50
add $275+137.50 =$387.50
( [72-60] / 72 )*100 = 50 / 3 = 16.7 %
X=y-7
x=2-8y
both equal x so
subsitute y-7 for x in other equaton
y-7=2-8y
add 8y
9y-7=2
add 7
9y=9
divide 9
y=1
sub back
x=y-7
x=1-7
x=-6
(x,y)
(-6,1)
