Step-by-step explanation:
Answer:
Apoint on negative x-axis
The original price of the item will be $ 480.When there is 75% off on the original price.
<h3>What is the percentage?</h3>
The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.
The right question is
"Joyce saved $120 on an item that was 75 % off. What was the original price?"
Given data;
% off = 75
Amount saved $120
Let the original price of the item is x
75 % of x + $120 = x
0.75x+ 120 =x
0.25 x =120
x=120/0.25
x=480
Hence, the original price of the item will be $ 480.

Answer:
45
Step-by-step explanation:
![{a}^{2} + {b}^{2} = {c}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20%20%3D%20%20%7Bc%7D%5E%7B2%7D%20)
ssubstitute a and b for any of the numbers (3 or 6) and get 36+9 which is 45
45 =
![{c}^{2}](https://tex.z-dn.net/?f=%20%7Bc%7D%5E%7B2%7D%20)
so you would need to find the square root to get c
Usando las relaciones entre velocidad, distancia y tiempo, se encuentra que ella condujo a una velocidad media de 90,5 km/h.
--------------------------
La <u>velocidad </u><u>es la distancia dividida por el tiempo</u>, por lo que:
![v = \frac{d}{t}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D)
- Total de 135,75 km, o sea,
![d = 135,75](https://tex.z-dn.net/?f=d%20%3D%20135%2C75)
- Llego en 1,5 horas, o sea,
![t = 1,5](https://tex.z-dn.net/?f=t%20%3D%201%2C5)
La velocidad es:
![v = \frac{d}{t} = \frac{135,75}{1,5}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D%20%3D%20%5Cfrac%7B135%2C75%7D%7B1%2C5%7D)
División de decimales, o sea, seguimos multiplicando los números por 10 hasta que ninguno sea decimal:
![v = \frac{135,75}{1,5} = \frac{1357,5}{15} = \frac{13575}{150} = 90,5](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7B135%2C75%7D%7B1%2C5%7D%20%3D%20%5Cfrac%7B1357%2C5%7D%7B15%7D%20%3D%20%5Cfrac%7B13575%7D%7B150%7D%20%3D%2090%2C5)
Ella condujo a una velocidad media de 90,5 km/h.
