Answer:
The distance from Simon's house to the beach is 137.5 miles
Step-by-step explanation:
we know that
The speed is equal to the ratio of the distance and the time
Let
s ----> the speed in mph
x ----> the distance in miles
y ---> the time in hours
![s=\frac{x}{y}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7Bx%7D%7By%7D)
we have
![s=55\ mi/h](https://tex.z-dn.net/?f=s%3D55%5C%20mi%2Fh)
![y=2\frac{1}{2}\ h=\frac{2*2+1}{2}=\frac{5}{2}\ h](https://tex.z-dn.net/?f=y%3D2%5Cfrac%7B1%7D%7B2%7D%5C%20h%3D%5Cfrac%7B2%2A2%2B1%7D%7B2%7D%3D%5Cfrac%7B5%7D%7B2%7D%5C%20h)
substitute in the formula and solve for x
![55=\frac{x}{(5/2)}](https://tex.z-dn.net/?f=55%3D%5Cfrac%7Bx%7D%7B%285%2F2%29%7D)
![x=(5/2)55\\x=137.5\ mi](https://tex.z-dn.net/?f=x%3D%285%2F2%2955%5C%5Cx%3D137.5%5C%20mi)
Answer:
20 noisemakers; 40 balloons; 5 napkins
Step-by-step explanation:
n = noisemakers amount
b = balloons amount
k = napkins amount
n/4 = k
b = 2n
b + n + k= 65
plug first and second equation into the respected variables in the 3rd equation so:
2n + n + n/4 = 65
multiple both sides by 4 to get rid of fraction
4(2n + n + n/4) = 4*65
8n + 4n + n = 260
13n = 260
n = 20
use n = 13 to get the other variables
b = 2(20)
b = 40
(20)/4 = k
k = 5
