The sum of all the angles in a triangle is equal to 180 degrees
x = 180-(65+30) = 85 degrees
A + b = 80 + 45 = 125
Therefore, C is your answer.
Answer:
My guess:
A. Consistent independent
B. Consistent dependent
C. Inconsistent
Step-by-step explanation:
The first is a repeated equation, so it is a consistent independent equation.
The second is consistent, trying to solve the value of Y. But it looks like it needs the other equation to complete it and solve the value of Y.
The third has no pattern, and isn't trying to solve any values, unlike the others. So it is inconsistent.
(Just a quick note, I do not have experience with this, but it is my best guess)
Answer:
The second photo.
Step-by-step explanation:
If you use a graphing calculator, you can easily find the answer.
Answer:
36 students
Step-by-step explanation:
1. Set up a proportion. Since we are trying to find out the number of students in the class, that number will be x. We can say that 20/x=55/100, because 55% is 55/100.
2. Simplify in which we can find x. Multiply x on both sides and multiply by 100 on both sides (or just cross multiply). You would get that 55x=2000, and if you divide by 55 on both sides, it would be x = 36.3636364, and since you can't have a fraction of a person, you round it to the nearest whole number.
Answer: There are 36 students in the class.
