At what time the sum Rs. 5000 will be doubled at the interest<br>of 10% per annum?

FromTheMoon [43]

Answer:

Time= $10$ years

Step-by-step explanation:

Let total time $=t$

Initial Amount $=5000$

Final Amount $=10000$

Total interest = Final Amount - Initial Amount

$=10000-5000\\=5000$

Simple Interest $=\frac{Initial Amount\times time\times rate}{100} \\\\5000=\frac{5000\times t \times 10}{100}\\\frac{t}{10} =1\\t=10 \ years$

For what values of x'is x2 + 2x = 24 true?

Paladinen [302]

Answer:

$\boxed{Values \: true \: of \: 'x' \: for \: equation \: {x}^{2} + 2x = 24 \: is \: -6 \: and \: 4}$

Step-by-step explanation:

$= > {x}^{2} + 2x = 24 \\ \\ = > {x}^{2} + 2x - 24 = 0 \\ \\ = > {x}^{2} + (6 - 4)x - 24 = 0 \\ \\ = > {x}^{2} + 6x - 4x - 24 = 0 \\ \\ = > x(x + 6) - 4(x + 6) = 0 \\ \\ = > (x + 6)(x - 4) = 0 \\ \\ = > x + 6 = 0 \: \: \: \: \: \: \: \: and \: \: \: \: \: \: \: \: \: x - 4 = 0 \\ \\ = > x = - 6 \: \: \: \: \: \: \: \: \: \: and \: \: \: \: \: \: \: \: \: x = 4$

Values true of 'x' for equation x² + 2x = 24 is -6 and 4
