You need the total amount of how many animals
For the first one the slope is 0.5
For the second one the slope is -1.7
Volume of a sphere is 4/3(pi r ^3)
You were given d = 10 so r = 5
Then just plug and chug
Answer:
C -16x + 74/5
Step-by-step explanation:
2(x + 7) - 18x + (4/5)
Expand the brackets.
2x + 14 - 18x + (4/5)
Combine like terms.
(2x - 18x) + (14 + (4/5))
-16x + 14 4/5
Convert 14 4/5 to an improper fraction
14 4/5 = ((14 * 5) + 4) / 5 = 74 / 5
Answer = -16x + 74/5
