Answer:
x = 80.96
Step-by-step explanation:
9x * 3x +1 = 2187
27x +1 = 2187
27x = 2187-1
27x = 2186
x = 2186/27 = 80.96(2dp)
You don't have the answer choices but if there were no decomposers within an ecosystem, some plants could die due to a shortage of nutrients
.
3x - 2 < 12
3x < 12 + 2
3x < 14
x < 14/3
x < 4 2/3......whole-number value = 4
