Let x be the number of students in Emily's class such that 75% of x is 15.
15 = 0.75x
The value of x is equal to 20.
Let y be the number of students in Santiago's class. Similar with what we did previously,
12 = (2/3)y
The value of y is equal to 18.
Therefore, there are more student's in Emily's class than in Santiago's class.
Answer: 17%
Step-by-step explanation:
1. First divide the percentages by 100 to turn the percentages into a decimal (28/100) x (63/100) = 0.1764
2. Then turn that decimal into a percentage again.
0.1764 x 100 = 17.64 but if you’re rounding to the nearest tenth without any decimals it’ll just be 17%
Well, this answer is easy because.... n is an obtuse angle (more than 90 degrees) and there is only 1 answer that is more than 90 degrees.
So, the correct answer is D. 95°
Answer:
9x-3
Step-by-step explanation:
To do this, we can make an equation and add like terms.
The equation is 2x+3x-1+4x-2=p. P stands for perimeter.
Now, simplify. Add like terms.
9x-1-2=p
9x-3=p
9x-3
The answer is D. 9x-3
Hope this helps!
