Answer:
Third option: 80 people.
Step-by-step explanation:
Let be "x" the number of people that were surveyed.
You know that 48 people chose winter as their favorite season and these amount of people are the 60% of those questioned.
Knowing this, you can calculate the number of people that were surveyed with this procedure:
![x=\frac{(48\ people)(100\%)}{60\%}\\\\x=(48\ people)(\frac{5}{3})\\\\x=80\ people](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B%2848%5C%20people%29%28100%5C%25%29%7D%7B60%5C%25%7D%5C%5C%5C%5Cx%3D%2848%5C%20people%29%28%5Cfrac%7B5%7D%7B3%7D%29%5C%5C%5C%5Cx%3D80%5C%20people)
Therefore, 80 people were surveyed. This matches with the third option.
Answer:
Step-by-step explanation:
The error occured where the distributive property was applied. 3 × -4 should give us -12 not +12.
Here's the correct way to solve the equation
3(x - 4) = -9
3x - 12 = -9 (distributive property)
3x - 12 + 12 = -9 + 12 (addition property of equality)
3x = 3
3x/3 = 3/3 (division property of equality)
x = 1
Solution:
we have been asked to find
15 is what percentage of 60.
Let 15 is x% of 60.
Then we can write
![60*x \ percentage=15\\ \\ 60*\frac{x}{100}=15\\ \\ \text{Apply the concept of cross Multiplication we get}\\ \\ 60x=1500\\ \\ x=\frac{1500}{60}\\ \\ x=\frac{150}{6}\\ \\ x=25\\](https://tex.z-dn.net/?f=%2060%2Ax%20%5C%20percentage%3D15%5C%5C%20%5C%5C%2060%2A%5Cfrac%7Bx%7D%7B100%7D%3D15%5C%5C%20%5C%5C%20%5Ctext%7BApply%20the%20concept%20of%20cross%20Multiplication%20we%20get%7D%5C%5C%20%20%5C%5C%2060x%3D1500%5C%5C%20%5C%5C%20x%3D%5Cfrac%7B1500%7D%7B60%7D%5C%5C%20%5C%5C%20x%3D%5Cfrac%7B150%7D%7B6%7D%5C%5C%20%5C%5C%20x%3D25%5C%5C%20%20%20)
Hence 15 is 25% of 60.
Let's go with 114.
Every 0 will represent a 10 and every I will represent a 1.
