2 + d = 2 - 3(d- 5) - 2
First, cancel 2 on both sides. / Your problem should look like:
Second, expand. / Your problem should look like:
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like:
Fourth, add 3d to both sides. / Your problem should look like:
Fifth, add d + 3d to get 4d. / Your problem should look like:
Sixth, divide both sides by 4. / Your problem should look like:

If the whole diameter of sphere is 6 inch(means radius is 3 inch) & thickness of material is 1 inch, so the radius of the hollow part should be 2 inch (3-1=2)
The total volume of the ball will be;
= Total volume - Volume of hollow part
= 4/3πr³ - 4/3πr³
= 4/3 × 3.14 × (3)³ - 4/3×3.14×(2)³
= 4 × 3.14 × 9 - 4/3 × 3.14 × 8
= 113.04 - 33.52
= 79.52
If the density of the material is 3.25 g/in3, then the density of 79.52 inch³ should be;
= 79.52 × 3.25
= 258.44 g
Now, if there are 8 spheres in one box, the weight if box will be;
= 258.44 × 8
= 2,067.52 g

Answer:
(c) Equation which can be used to find r, the cost in dollars to park s nights is r = 24.99 s
Step-by-step explanation:
Here, the parking cost of 1 night at the airport = $24.99
Now, here the total number of nights the car is parked at airport = s
R = The total cost of parking s nights
Now, The cost for parking s nights = s x ( Cost of parking 1 night)
= s x ($24.99) = 24.99 s
Also the cost for parking s nights = r
⇒ r = 24.99 s
Hence, equation which can be used to find r, the cost in dollars to park s nights is r = 24.99 s
