Let x be the number of students in the class the
the number of students in the class when 1 in 4 are absent = x - 0.25x = 0.75x
After Jen returns there are x - 0.2x = 0.80x so we have the equation
0.75x + 1 = 0.80x
0.05x = 1
x = 1 / 0.05 = 20 Answer
So there are 20 students in the class.
No. students not here today = 0.80 * 20 = 16 Answer
Answer: The answer is C) lll.
A) I.
B) II.
C) III.
D) IV.
Step-by-step explanation:
If a < 0 and b < 0, then the point (a, b) is in Quadrant
5A + 7 = 3A + 7 + 2A
We need to solve for A.
3A + 7 + 2A = 3A + 2A + 7 = 5A + 7 (We can add 3A and 2A because it's the same variable, so we add the coefficients)
5A + 7 = 3A + 7 + 2A
5A + 7 = 5A + 7
5A + 7 is always equal to 5A + 7 because it's the same equation. So the equation got infinitely many solutions.
Answer: Y-48
<span>If the median of the values in the data set is Y, it means that Y is the value in the middle of the data set. If 48 will be deducted from each of all values in the data set including Y, then the median of the resulting value will be Y-48. </span>
