B
Step-by-step explanation:
3 out of 10 is smaller than 3 out of 5
Answer:
x=o and y= -6
Step-by-step explanation:
12-2x = - 2(y-x)
or,12-2x = -2y + 2x
or, 12 = - 2y + 4x
or, 12/2= 2x - y
or, 2x - y = 6
• 2x -6= y.....eqn_1
-2x=-2y+2x -12
or,4x +2y= -12
or,4x + 2(2x-6)= -12
or, 4x+4x-12=-12
or, 8x= 0
• x= o
putting the value of x in eqn...3
o=(y-0)+6
or, o= y + 6
•y = -6
Answer:
y will increase by 8
Step-by-step explanation:
y = 8x+2
We increase x by 1
Replace x with x+1
y = 8(x+1) +2
y = 8x+8+2
y = 8x+2 +8
y will increase by 8
Answer: 24 students
Explanation:
(20 + 23 + 25 + 28)/4
= 96/4
= 24
Therefore the mean is 24 students in the class.
