Positive 18, going off the assumption that the tick 2 spaces away from -1 is positive 9.
Me neither. I used to know, good luck!

Answer:
80 ft
Step-by-step explanation:
<em>hey there,</em>

< We know that the rope is 3 pieces long. To make this into an equation, let's just write x + y + z = 150.
Assuming "y" is our second piece, we can tell y = 2x, because it is two times the size of the first piece, which is "x". We also know "z" (our third piece): z = 30.
We can try inputting all the things we know now. x + (2x) + 30 = 150. From here, we can find that x = 40. Since y is our second piece, y = 2x, so 2 x (40) = 80. The second piece would be 80 feet long. >
