Answer:

5 , 8

Step-by-step explanation:

6x - 1 = 3x

Subtract 3x from both sides

6x - 3x - 1 = 3x - 3x

3x - 1 = 0

Add 1 to both sides

3x - 1 + 1 = 0 + 1

3x = 1

Divide both sides by 3

3x/3 = 1/3

x = 1/3

15x = 15(1/3)

= 15/3

= 5

24x = 24(1/3)

= 24/3

= 8

Let ∠X and ∠Y be complementary. If sin(X) = 3/5

statuscvo [17]

Since they are complementary
x + y = 90

Sin(o) = Cos (90-0)

Therefore, Cos x = Sin y = 4/5 [ Because x and y are complementary]

$\bf i^5\implies i^4i\implies 1i\implies i
\\\\\\
32=2^5\\\\
-------------------------------\\\\
x^5-32i=0\implies x^5=32i\implies x=\sqrt[5]{32i}\implies x=\sqrt[5]{2^5i^5}
\\\\\\
x=\sqrt[5]{(2i)^5}\implies x=2i\implies x=0+2i\implies (0~,~2)$

The quotient of 5n^2(m^2+2m-3)/10n(m^2-3m+2) divided by n^2(m^2-3m-18)/4n^2(m^2-8m+12)

slavikrds [6]

$\dfrac{ 5n^2(m^2+2m-3)}{10n(m^2-3m+2)} \div \dfrac{n^2(m^2-3m-18)}{4n^2(m^2-8m+12)}$

$\dfrac{ 5n^2 (m + 3)(m - 1)}{10n( (m - 1)(m - 2)} \div \dfrac{n^2(m + 3)(m - 6)}{4n^2(m - 2)(m - 6)}$

$\dfrac{ 5n^2 (m + 3)(m - 1)}{10n( (m - 1)(m - 2)} \times \dfrac{4n^2(m - 2)(m - 6)}{n^2(m + 3)(m - 6)}$

$= 2n$
