Step-by-step explanation:
Answer:
42 feet
Step-by-step explanation:
Substitution doesn't work for this, but elimination does.
-6x-8y=-20 +6( x+6y=-6)
-6x-8y=-20 + 6x+36y=-36
-6x and 6x cancel each other, add -8 and 36 to get 28, and -20 and -36 to get -56.
28y=-56
divide by 28 on both sides.
Y= -2
Then substitute y into one of the equations.
x+6(-2)=-6
x-12=-6
x=6
The ordered pair is (6,-2).
Solve the parenthesis firt.
17-9 = 8
3*2 = 6 now multiply 6 by 8 that equals 48
now divide 48 by 2
48÷2= 24
