How do you solve equations like this? How do you multiply whole positive numbers by negative fractions? The question in the picture: What is the sign of 9 • (-0.5)?

The answer to this problem isn't necessary, but I'd appreciate it if it was included <3

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

What value of x is in the solution set of 4x – 12 s 16 + 8x?

Suppose a store sells an average of 80 cases of soda per day. assume that each case contains 24 cans of soda and that the store is open 10 hours per day. find the average number of soda that the store sells per hour.
