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:

Step-by-step explanation:
Cubes have 6 sides
you have 2 cubes
there are 3 ways to get a 6
1+5 -> 2+4 -> 3+3
Part a. is correct. It is 150.
Part b.
First plan: $30 + $0.20 per text
For 50 texts
$30 + 0.20 * 50 = $30 + $10 = $40
For 50 texts, the first plan costs $40
For 50 texts per month, the first plan is better because it costs only $40 instead of $60
Second plan: $60 no matter how many texts
