Answer:
x = 9
Step-by-step explanation:
Sum of all angles of a triangle = 180
63 + 7x + 6x = 180
63 + 13x =180
13x = 180 - 63
13x = 117
x = 117/13
x = 9

Each mile took 7.5 minutes. So we did this by dividing 30 by 4. Hope this helped you :)
Number of faces + (Number of vertices - Number of edges) = 2
So plugging in the numbers it would then be
18+(12-30)=2
18-18=2
0=2
Kelvin would be wrong and I disagree with him. (Because ...*plugin work cited above*)
-12>/5x-9
+9 A Los dos lados
-3>/5x
÷5 Los dos lados
-3/5 >/ x
x </ -3/5
