Solving equations: (a) 5x - 9 = 3x + 3 (b) x + 6 = 34 - x
(c) 6x - 8 = 2 - 5

Thankyou.

a ) 5x - 9 = 3x + 3

5x - 3 = 3+9

2x = 12

x = 12/2

x = 6

b) x+6= 34-x

x+x = 34 - 6

2x = 28

x = 28 / 2

x = 14

c) 6x - 8 = 2 - 5

6x - 8 = - 3

6x = - 3 + 8

6x = 5

x = 5/6

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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
