1/3x + 5 = -2 is the way to set up the equation…. You got this!
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)

<span>2.204 x 10^9 is the correct answer.</span>
Ok so 40y2/50y3.... you are going to cancel out the common factor (10)
4y2/5y3..
now apply the exponent rule, which is : xa /xb = 1/ xb-a
so...y2/y3 = 1/ y3 - 2 = 1/y
ANSWER : 4/5y
