Step-by-step explanation:

This is a common knowledge of equivalent fractions.

Multiplying both the numerator and denominator of a fraction by the same quantity does not change the value of the fraction.

Not only multiplication, but division also works. What ever operation performed on the numerator must also be performed on the denominator.

1/2 = 2/4 = 4/8 = 16/32

morpeh [17]

Answer: (1,4)

Step-by-step explanation:

Given

Equation of line is $2y-3x=5$

(-1,1) is the solution of the equation

Take x=1 and substitute it in the above equation

$\Rightarrow 2y-3(1)=5\\\Rightarrow 2y=5+3\\\Rightarrow y=4$

So, another pair of the solution is (1,4)

Can someone help me with this question please !

RoseWind [281]

Answer:

a) A triangle which the angles ratio is 1 : 2 : 3 is a 30º - 60º - 90º right triangle.

b) The shortest side is opposite to the shortest angle. So, we can calculate it using sin 30º.

$\text{sin}(30\º)=\frac{\text{Opposite side to x}}{19}$

$\frac{1}{2} =\frac{\text{Opposite side to x}}{19}$

$\text{Opposite side to x}= 9.5$

Factor. Explain.<br> 24x³y²-4x²y+84x^4

Elan Coil [88]

Answer:

$\boxed{\bold{4x^2\left(6xy^2-y+21x^2\right)}}$

Step By Step Explanation:

Apply Exponent Rule $\bold{\:a^{b+c}=a^ba^c}$

$\bold{x^4=x^2x^2,\:x^3y^2=x^2x}$

$\bold{24x^2x-4x^2y+84x^2x^2}$

Rewrite 84: $\bold{21\cdot \:4}$

Rewrite 24: $\bold{6\cdot \:4}$

$\bold{6\cdot \:4x^2x-4x^2y+21\cdot \:4x^2x^2}$

Factor Out Common Term $\bold{4x^2}$

$\bold{4x^2\left(6xy^2-y+21x^2\right)}$

➤ $\boxed{\bold{Mordancy}}$

Se tiene la sucesión 3, 8, 13, 18, 23 … ¿Cuáles son los siguientes dos términos y cuál es la regla general?

V125BC [204]

Respuesta:

28; 33

A (n) = 5n - 2

Explicación paso a paso:

A partir de los datos dados, 3, 8, 13, 18, 23…, podemos ver que cada valor sucesivo de la serie aumenta en 5;

Por lo tanto, los siguientes dos términos de la serie deberían ser:

23 + 5 = 28

28 + 5 = 33

La serie es una progresión aritmética:

Recuerde la fórmula general:

A (norte) = a + (norte - 1) d

Donde, a = Primer término = 3; d = diferencia común = 5

n = enésimo término

A (n) = 3 + (n-1) 5

A (n) = 3 + 5n - 5

A (n) = 5n - 2
