Question

if A varies inversely as B+2 and if A=8,when B=1.5 find A when B=5​

Answer 1

Answer:

Given , a ∝ 1/b+2 .

a₁ /a ₂ =b₂+2 / b₁ +2 .

Given a₁ =8 , b₁ =1.5

b₂=5 .

8/a₂ = 5+2 / 1.5 +2

=> 8/a₂ = 7/3.5

=>8/a₂ = 2

=> a₂ =8/2

=> a₂ =4 .

Therefore,when b = 5 , then a =4

Hope it helps you !

Answer 2

Answer:

my answer is 4

Step-by-step explanation:

a is inversely proportional to b

if a=8 when b=1.5

then a=4 when b=5
