(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

Answer:

$5.5

Step-by-step explanation:

6 * N (notebook) + 3 * P (pen) = 27

n = 1.5 +P

6 * (1.5 + P) + 3 * P = 27

9 +6p +3p = 27

9p = 18

p (pen): $2

N (notebook): $3.5

combined cost of 1 pen and 1 notebook: $2 + $ 3.5 = $ 5.5

Refer to the data above. What number represents the slope of the line, if the points on the graph above were joined?
Dmitrij [34]

Answer:

slope = 40

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (2, 80) and (x₂, y₂ ) = (4, 160) ← 2 points on the line

m = \frac{160-80}{4-2} = \frac{80}{2} = \frac{40}{1} = 40
