Answer:
4x + 15
Step-by-step explanation:
Let the age of Khairul's uncle y.
From the question given above, the following were obtained:
Khairul's age = x years
In 5 years time:
Khairul's age = x + 5
Khairul's uncle age = y + 5
But from the question given above,
Khairul`s uncle will be 4 times as old as what khairul will be in 5 years. This can be written as follow:
y + 5 = 4(x + 5)
Clear bracket
y + 5 = 4x + 20
Subtract 5 from both side
y + 5 – 5 = 4x + 20 – 5
y = 4x + 15
Therefore, Khairul's uncle present age is 4x + 15
ANSWER
Biodiversity index = 0.096
EXPLANATION
Given 7 different organisms with their individual numbers.
Biodiversity Index is:

i.e:

Hence, the Biodiversity Index of Fraya's local park is 0.096. This is a low biodiversity since it's closer to 0.
5% or 5percent can be thought of 5 per 100.
5 per 100 or 5 out of 100 can be written as 5/100 or 1/20.
An hour have 60 minutes and 1/20 of an hour is 60*1/20=3 minutes.
Therefore Sara can work 3 minutes every hour.
3(1/3) + 3/(1/3) = 1+9
Answer : 10
