The answer to your question is,
$8.84, since when you divide the numbers 67.99 and 13%, you get $8.84.
-Mabel <3
2(x+2)=3(x-3)
2x+4=3x-9
2x=3x-13
-x=-13
x=13
The number is 13
Correct answer is D).
A) and C) are polynomials, so x∈R, in B) we have √x, and in this case x ≥ 0.
For Samantha, 2 tick marks east is 120 units east because 1 tick is 60 units.
For Ryu, 8 tick marks west is 480 units west because 1 tick is 60 units.
They are walking to form a line. Just add their distances from 0.
120 + 480 = 600.

Ryu: 480 Samantha: 120
480 + 120 = 600.
600 units, or feet.
