Step-by-step explanation:
The correct answer for the question that is being presented above is this one: "C) 1.6." Hank is painting his grandfather's fence. He painted 40 linear feet in 85 minutes. He still has 360 linear feet to paint. His cousins, Sam and Alex, come <span>to help. Sam paints twice as fast and Alex paints half as fast as Hank. The constant of proportionality that relates the current fence painting rate is 1.6.</span>
1) in one minute for first wiil be 1/20
the other 1/30, it means that A paint in one minute 1/20 and B 1/30 then A+B in one minute 1/20 + 1/30 = 3+2/60 = 5 / 60, 5/60 = 1/12
if in one min they make 1/12 then in 12 min they paint all the wall
It is not true
6pack = 6 pieces ?
6 pieces for $2.00 = $12 not $2.99
Devon should divide $2.99/6 ~~ $0.49
If you subtract the equation 8.0-8.2=-0.2. If you were to do the opposite then you would answer the equation 8.2-8.0=0.2. So therefore you have two options, -0.2 or 0.2. Good luck!
