Translate the following into an algebraic expression: A number is 30% of 20% of the number x.
bezimeni [28]

Answer: 0.06x

Step-by-step explanation:

  • An algebraic expression is an expression consist of integer constants, variables, and algebraic operations.

The given statement:  A number is 30% of 20% of the number x.

The required algebraic expression would be:

30% of 20% of x

=\dfrac{30}{100}\times \dfrac{20}{100}\times x  [we divide a percentage by 100 to convert it into decimal]

=\dfrac{6}{100}\times x\\\\=0.06x

Hence, the required algebraic expression would be :

0.06x

P partitions GR in ratio 2:4. GR is 36cm. How long is GP and PR?
Allushta [10]

Answer:

12 cm and 24 cm

Step-by-step explanation:

The line is divided in the ratio 2 : 4 = 2x : 4x ( x is a multiplier )

The sum is therefore

2x + 4x = 36

6x = 36 ( divide both sides by 6 )

x = 6

Thus

GP =  2x = 2 × 6 = 12 cm

PR = 4x = 4 × 6 = 24 cm
