What is the solution to the system of equations below? 2x + 3y = 6
x - 3y = 9
-1.
(A)
(B) (-3,-4)
5,
(C)
8,
3
3
(D)

x = 5

y = -4/3

Step-by-step explanation:

2x + 3y = 6

x - 3y = 9

Substitution Method:

x = 3y + 9

2(3y+9) + 3y = 6

6y + 18 + 3y = 6

9y = -12

y = -12/9 or -4/3

x - 3(-4/3) = 9

x + 4 = 9

x = 5

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
