I agree with EP's first answer........
I see the second situation a little differently
We can arrange Larry, Curly and Moe in 3! ways in the front row and the other students in 6! ways in the other desks....so
3! * 6! = 4320 arrangements
92/80 =
1.15 goals per game
8(x + 5) − 2(x + 3) = 46 simplify
8x + 40 - 2x - 6 = 46
6x + 34 = 46 subtract 34 from both sides
6x = 12 divide by 6
x = 2
12/4 = 3 so
3 miles in 1/8 multiply both by 8 =
24 miles n 1
True....this is the definition of absolute value for real numbers
2cos3x = 1 divide by 2
cos (3x) = 1/2
Now
cos (3x) = 1/2 at 3x = pi/3, 5pi/3 , 7pi/3, ......so
x = pi/9, 5pi/9, 7pi/9
The cosine returns values between -1 and 1. inclusively....so....
cos x = 81 is undefined.....however....maybe you're trying to find the cosine of 81° ??
cos (81°) = 0.15643446504
14! / [ 5! * 6! * 3! ] = 168,168
