Answer:
a = 4
Step-by-step explanation:
Given equation:
4a - 5 = 11
Add 5 to both sides:
⇒ 4a - 5 + 5 = 11 + 5
⇒ 4a = 16
Divide both sides by 4:
⇒ 4a ÷ 4 = 16 ÷ 4
⇒ a = 4

Answer: y = 3
Step-by-step explanation:
Answer:
3.38/6.21=54.428% (0.54428)
Step-by-step explanation:
biocapacity of grazing land of 0.85 ha/person+biocapacity of forest land of 2.53 ha/person
2.53+0.85=3.38
the percentage of biocapacity from grazing and forest land
3.38/6.21=54.428% (0.54428)
