Answer:
x =
, y = -1.71
Step-by-step explanation:
sub y = x+4 in the first equation to get:
12 x - 5 (x+4) = -20
Simplify:
12 x - 5 x + 20 = -20
Further simplify:
7 x = - 40
Divie both sides by 7 to get:
x =
--> x = -5.7
Sub x =
in the second equation to get:
y =
+ 4 = -1.71
Step-by-step explanation:
small circle
C= pi D
C = 3.1415(9)
C= 28.3 ft
large circle
C= 2(3.1415)(7)
C = 44 ft
Add 28.3 + 44 = 72.3 ft
4•4=16
12•5=60. That’s the answer
