Answer:
6/12 × 3/2
Step-by-step explanation:
To divide the fractions we turn the second fraction upside down and multiply two fractions
So, 6/12 ÷ 2/3 is equal to 6/12 × 3/2
The mean is 35/5=7
v=((7-7)^2+(5-7)^2+(11-7)^2+(1-7)^2+(11-7)^2)/5
v=(0+4+16+36+16)/5
v=14.4
Answer:
-2x + 7x + 34 = -2 ( 1 - 7 x ) x=4
2x + y = 3
3x - y = 12
Add both equations
5x = 15, x = 3
2(3) + y = 3
6 + y = 3, y = -3
Solution: x = 3, y = -3... or (3,-3)
She played 8 games. Since she earned a total of 120 points and 15 points per game you would divide 120/15=8
