Answer:
1 is x=12
2 is x= 1/5
Step-by-step explanation:
For equation number 1 you just add 10 and 2, which is 12.
For equation number 2 you divide 2 by 10 and simplify it to 1/5. So x = 1/5
55mph.
you can solve it using the equation distance=speed x time
your total distance is 714, and you have 2 trains, one traveling some speed, x, and one traveling x+8, both traveling for 7 hours.
your equation would look like this

and you can then solve for x, which would be 47. this is the speed of the slower train, but 47+8=55 with give you the speed of the faster train.
Direct variation is
y=kx
subsitute
-6=-36k
diivde both sdies by -36
1/6=k
the equation is
y=1/6x or B
