Sienna runs 12 laps around the school track in 6 minutes. What are her unit rates of speed?

When 142 is added to a number the result is 64 more then 3 times the number. option 35 37 39 41

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.

If p(a) = 0.70 and p(b) = 0.20, then a and b are independent events if
