80+20 is ten times 8+2, if you factor out 10 from 80+20 we get 10(8+2)

Adding 8+2 is the same as adding 80+20 all your going is adding the zero
80+20=100

Nadusha1986 [10]

Answer:

0

Step-by-step explanation:

Given

- 0.4(3x - 2) + \frac{2x+4}{3} ← substitute x = 4 into the expression

= - 0.4(3(4) - 2) + \frac{2(4)+4}{3}

= - 0.4(12 - 2) + \frac{8+4}{3}

= - 0.4(10) + \frac{12}{3}

= - 4 + 4 = 0

Do I solve this by equaling both equations to each other?
Mars2501 [29]
Yes, you got it! You would need to set the equations equal to each other, because that represents when their populations are the same. Then, solving for x will find the time in months until you reach that equilibrium in population. If you need help solving for x, just comment on this. Hope it helps!

Answer:

125π km³

Step-by-step explanation:

We are to find the Volume of a cylinder

From the question:

Height of the cylinder = 5km

Radius of the cylinder = 5 km

The volume of a cylinder =

πr² h

Hence:

π × 5² × 5

= 125π km³

The volume of the cylinder = 125π km³

Option d is the correct option
