50 = -5 (6n + 8)
What is the answer?

n=3

Step-by-step explanation:

-5 (6n +8) =50

First distribute the -5 to 6n and 8. Remember to multiply with the sign!

so -5 x 6n and -5 x 8

which = -30n and -40

so our new equation is

-30n - 40=50

we add 40 to the other side since we want the answer of the variable

-30n - 40 +40 = 50+40

-30n =90

we divide -30 from n to get n alone.

-30n/-30 = 90/-30

n=-3

We can check our answer by plugging it into the equation.

50= -5 (6(-3) +8)

50 = -5 (-18+8) -> 50= -5 (-10)=50

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
