Let x is the small drink
x +0.5 is the large drink (cause large drink cost 50 cents more than small drink)
<span>3 small drinks and 2 large drinks</span> should be:
3x + 2(x +0.5)
= 3x + 2x + 1

Answer:
When you have two negative signs, one turns over, and they add together to make a positive. If you have a positive and a negative, there is one dash left over, and the answer is negative.
Step-by-step explanation:
You gave us the speed and the frequency, and you need the wavelength.
You were also nice enough to remind us that (fqy)x(lng) = speed.
So . . . F x W = 343 m/s
Divide each side by F :
W = (343 m/s) / F
W = (343 m/s) / (240 / s)
W = (343/240) m
<em>W = 1.429 meters</em>
