he volume of a fish tank is 50 cubic feet. If the density is 0.2 fish over feet cubed, how many fish are in the tank?

V125BC [204]

There are 10 fish in the tank

Solution:

Given that, volume of a tank is 50 cubic feet

Density is 0.2 fish over feet cubed

To find: Number of fish in the tank

Number of fish in the tank is found by multiplying the volume of tank and density

The formula is given by:

$\text{Number of fish} = \tex{\text{volume of tank}} \times {\text{density of fish over feet cubed}}$

Substituting the given values, we get

$\text{Number of fish} = 50 ft^3 \times \frac{\text{ 0.2 fish}}{ft^3}\\\\ \text{Number of fish} = 50 \times 0.2 \text{ fish }\\\\ \text{Number of fish} = 10 \text{ fish }$

Thus there are 10 fish in the tank

Number 12.

const2013 [10]

given the 2 equations

x + 2y = - 8 → (1)

- 4x + y = 5 → (2)

multiply (1) by 4

4x + 8y = - 32 → (3)

add (2) and (3) term by term to eliminate term in x

9y = - 27 ( divide both sides by 9 )

y = - 3

substitute y = - 3 in either (1) or (2) and solve for x

(1) : x - 6 = - 8 ( add 6 to both sides )

x = - 2

solution is (- 2, - 3 ) → D
