6x-7y=8 x+5y=11 round to the nearest hundredth

-6x-7y=8

x+5y=11 so x = -5y + 11

Substitute x = -5y + 11 into -6x-7y=8

-6(-5y + 11) -7y = 8

30y - 66 - 7y = 8

23y = 74

y = 74/23

y = 3.22 (round to the nearest hundredth)

x = -5y + 11

x = -5(74/23) + 11

x = -16.09 + 11

x = -5.09

Answer

x = -5.09 and y = 3.22

-6x-7y=8

6x+30y=66

23y=74

y=3.22

x+5(3.22)=11

x+16.1=11

x=-5.1

this is false ^.^ lol

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.
