(a) how much potting soil he bought last week
(b) 28 = 2p + 4
(c) 28 = 2p + 4....subtract 4 from both sides
28 - 4 = 2p...simplify
24 = 2p...divide both sides by 2
24/2 = p....simplify
12 = p......12 solves the equation
(d) He bought 12 lbs of potting soil last week
The correct answer to this is 11.2
hope that helps
To solve for the width simply multiply the two numbers:
width of sidewalk = 12 * (3 7/8)
Where 3 7/8 = 31/8
so calculating,
width of sidewalk = 12 * (31 / 8)
<span>width of sidewalk = 46.5 inches</span>
(-0.75,0)-(0,3) is the answer
