Question

4 | x – 2 | = 16
| x – 2 | = 16/4
| x – 2 | = 4
x – 2 = 4 or x – 2 = – 4
x = 4 + 2 or x = – 4 + 2
x is _ and _

Answer 1

Step-by-step explanation:

Subtracting a fraction from a whole

Rewrite the whole as a fraction using t2 as the denominator :

t t • t2

t = — = ——————

1 t2

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator.

Answer 2

Shobo's Age = 5 Years

Mother's Age = 30 Years

Step-by-step explanation:

Given:

• Mother's age is 6 times the present age of Shobo.
• After 5 years , Shobo's age will be one third of mother's age.

To Find:

• What are their present ages ?

Solution:

• Let the present age of Shobo is x years. Therefore,

Mother's age = 6 times of x

Mother's age = 6x years

[ After 5 years ]

Shobo's age = (x + 5) years

Now , A/q

⟹ (x + 5) = 1/3 × 6x

⟹ (x + 5) = 2x

⟹ 5 = 2x – x

⟹ 5 = x

So , present age of Shobo is 5 years & present age of Shobo's mother is 6(5) = 30 years.
