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.
625 ft² ------------------ 1 multicellular organisms
3750 ft² ------------------ x
x = (3750 x 1) / 625
x = 3750 / 625
x = 6
2.- Conclusion
3750 ft² can supply of oxygen 6 organisms.

Answer:
1/2
Step-by-step explanation:
5x - 3y = 15
5x - <u>5x</u> -3y = <u>- 5x</u> + 15
<u>-3y</u> = <u>-5x</u> + 15
3y = 5x - 15
divide all of them by 3...
y = 5/3 - 5
