Answer: B) 6x - 6 = 15x + 15

Step-by-step explanation:

To find our answer, we need to first work out each equation.

A) 6x - 15 = 6x + 15

First, cancel out the equal terms.

6x - 6x - 15 = 15

-15 = 15

This statement is false.

B) 6x - 6 = 15x + 15

-9x = 21

x = -7/3

<u>This statement has one solution. </u>

C) 6x - 6 = 6x + 15

-6 = 15

This statement is false.

D) 6x + 15= 6x + 15

15 = 15

This statement has infine solutions.

d = n/V We know: d = 0.3 fish/ft³. V = 30 ft³ n = ? d = n/V n = d * V n = 0.3 fish/ft³ * 30 ft³ n = 9 fish
