Angle a and b are C) supplementary angles
Answer:
Jada walked 
Elena walked 
Lin walked 
Step-by-step explanation:
Let
x----> total miles walked by Jada
y----> total miles walked by Elena
z----> total miles walked by Lin
we know that
-----> equation A
----->
------> equation B
------> equation C
Substitute equation C and equation B in equation A and solve for x




Find the value of y

Find the value of z

therefore
Jada walked 
Elena walked 
Lin walked 
Step-by-step explanation:
x=−y−2z+3
x=y+32z+1
x=13y+23z+13
Answer:
given us,
slope= 0
(x1y1)= (3,-3)
here
(y-y1) =m(x-x1)
or, (y+3)=0(x-3)
or (y+3)= x-3
or, x+y= -3-3
x+y= -6
Step-by-step explanation:
x+y= -6
