Answer:
6^-2 =0.02777777777
Step-by-step explanation:
let length of one piece = x
length of other piece = 236-x
one piece is three times the length of the other
x=3(236-x)
x=708-3x
4x=708
x=177
so first piece is 177 inches long and second piece is (236-177)= 59 inches long

Answer:
#6 is D
#7 is A
Step-by-step explanation:
#6
-1/3(6x+15)-3
Distribute the -1/3
-1/3 times 6x is -2x
-1/3 times 15 is -5
-2x-5-3
-2x=8
#7
-12z-5z=85
COmbine like terms
-17z=85
Divide both sides by -17
z=-5
Step-by-step explanation:
90° counterclockwise = 270° clockwise
Algebraic Representation : 270° clockwise turn,
( x , y ) ==> ( y , - x )
C ( 5 , 1 ) ==> C' ( 1 , - 5 )
