Determine whether the following system of equations is consistent or inconsistent and dependent or independent. y=1/2x+2 -x+2y=4

Step-by-step explanation:

y=1/2X +2 ,-X +2y= 4

2( y=1/2x +2)

2y= x+2

-x =x +2-4

-2x=-2

x=1 #

-1+2y=4

2y=4+1

2y=5

y=5/2

y=2.0

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
