Help pls thank you.

15\lb of course

Step-by-step explanation:

all u do is subtract the rate of change an youll get your answer

$0.50 / (lb)

Step-by-step explanation:

Let compare the price we have to pay for the 20-pound baggage and the 50-pound baggage. We are going to see that the 50-pound baggage costs $15. From this, we can see that the increase of the weight by 30 pounds resulted in the cost being $15 more. Now in order to find out the rate of change we divide $15 by 30 pounds so we know how much each pound costs, and so we get...

$15 / 30(lbs) = $0.50 / (lb)

i dont know sorry

step-by-step explanation:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
