Given 2/3x+18=1/2 as the original equation, which equation below demostrates the additive inverse property was performed?
a.2/3x+18=1/2-18
b.2/3x+18(2)=1/2(2)
c.2/3x-18=1/2
d.2/3x+18-18=1/2-18

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

they are simplified

step-by-step explanation:

a

step-by-step explanation:

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
