Ainat [17]

Answer:

The answer to your question is 6 organisms.

Step-by-step explanation:

Data

625 ft² -------- 1 multicellular organism

3750 ft² -- number of organisms

Process

1.- To know the number of organisms that can supply 3750 ft² of lawn, we need to use proportions and cross multiplication.

                    x = 3750 / 625

                    x = 6

2.- Conclusion

3750 ft² can supply of oxygen 6 organisms.

Given the equation 5x+23=-2x-12, which order of operations completely solves for x
Nadya [2.5K]

Answer:

x = - 5

Step-by-step explanation:

5x + 23 = - 2x - 12 ( add 2x to both sides )

7x + 23 = - 12 ( subtract 23 from both sides )

7x = - 35 ( divide both sides by 7 )

x = - 5
