<span>.99(15) = 1.35x
14.85 = 1.35x
14.85/1.35 = 11
I think it is 15. I am not sure about the proper way to solve this....I just know that if he sold 15 brownies, he could buy 11 packs with exactly no change left over.</span>
Bob found out that he can dig 8 inches down every minute. If he wants to put a 5 foot stick in the hole with 28 inches showing, how long does he have to dig?
(so to solve you convert 5 feet to 60 inches then do the equation -8x+60=28 then you add 8x to both sides, subtract 28 then divide by 8 leaving you with 4 minutes)
5.3 x 5.3 = 28.09cm would be the answer
It would be 12% of 50
50 * 12/100 = 600/100 = 6
so, 6 cars are red
Y = 8x - 11 using the slope-intercept form.
