Can you solve x 13x + 7 = 5x - 20
a)3(3/8)

b)1(5/8)

c)1(5/8)

d)3(3/8

x = - 3 3/8

Its negative 3 3/8

Step-by-step explanation:

13x + 7 = 5x - 20

Subtract 5x from both sides

8x + 7 = -20

Subtract 7 from both sides

8x = -27

Divide both sides by 8

x = -27/8

x = - 3 3/8

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
