1 x 3 x 5 x 7 x 9 = 3 x 5 x 7 x 9 = 15 x 7 x 9 = 105 x 9 = 945
7 x 9 = 63... 63 x 5 = 315
If the equation is (-9-7)x = -5, then x= .3125 or 5/16 If the equation is -9-7x = -5, then x = -.571428 or -4/7
5/7 ÷ 7/9 = 5/7 x 9/7 = (5 x 9)/(7 x 7) = 45/49
16 x 9 x 5 x 7 = 5040

9C5 = 9!/[(9 - 5)!5!] = 9!/(4!5!) = (9 x 8 x 7 x 6 x 5!)/(5! x 4 x 3 x 2 x 1) = 3 x 7 = 21
The LCM of 5, 7, and 9 is 315, which is the multiple of the highest power of prime factors in the given numbers (32 x 5 x 7).
16 x 9 x 5 x 7 = 5040
630 = 7 x 90 = 9 x 70 = 5 x 126 = 6 x 105
x=5
No. 5+9=14. 7+9=16, therefore x=7.
957 = (9 x 102) + (5 x 101) + (7 x 100) or (9 x 100) + (5 x 10) + (7 x 1)
Order of operations. Do subtraction last. 6 x 5 x 9 x 1 x 5=1350. 7-1350=-1343
