4(u+1)+5=6(u-1)+u

is there a solution

u = 4

Step-by-step explanation:

distribute and get 4u+4+1=6u-6+u

combine. 4u+6=7u-6

get variables on one side of the equation:

7u-4u=6+6

then combine like terms again

3u=12

divide both sides by 3 to get u alone

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
