Answer:
x = -1 ,y = -5
Step-by-step explanation:
--> -2x + 3y +3x-3y = 12-13
--> x= -1
then
--> -2(-1) +3y =-13
--> 2+3y= -13
--> 3y = -15
--> y =-15/3
--> y = -5
$27.55
29.95 x 8% (aka .08) = 2.396
29.95- 2.396 = 27.55
Answer:
a) 49
b) 100 (I'm assuming that the 2 was supposed to be a square)
Step-by-step explanation:
Substitute the value in for x (the value being 7):
7² = 49
(7 + 3)² = (10)² = 100
