3x - 2y = 17
2x + y = 30
*solve for both variables,

multiplying equation 2 by 2 and adding eq 1

3x-2y = 17

+4x+2y = 60 3

=

7x = 77

x = 77/7 = 11

then

y = (60-4x)/2 {from equation 3}

y = 60-44/2 = 16/2 = 8

then

x = 11

y = 8

step-by-step explanation:

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.
