1 answer:

Answer: A

To find something that is equivalent; multiply both numbers of a ratio by the same number.

For the first number: 1 times 2 is 2. Second number: 2 times 2 is 4.

Put those together, and you will have 2:4. Hope this helped!

Andrew uses the equation 25(x-4)=30 x, where x represents the number of sales, to determine the number of items he needs to sell

pshichka [43]

Hello,

Start off by distributing 25 to both x and -4

25 * X = 25x & 25 * -4 = -100

25x - 100 = 30

At this point, we add 100 to both sides so we can get 25 to be seperate from 100.

25x = 130

To get rid of the 25, divide it in both sides:

130/25 = 5.2

The answer would be 5.2

I hope this helps you with your assignment!

Despejar la variable 2x al cuadrado + 15= 113

Rudik [331]

Hola!

x = 7 , x = -7

Explicación:

Comienza restando 15 en cada lado:

$2x^{2} + 15 -15=113-15$

Usted obtiene:

$2x^{2} =98$

Ahora divide ambos lados por 2:

$\frac{2x^{2} }{2} =\frac{98}{2}$

Usted obtiene:

$x^{2} =49$

Como la ecuación está al cuadrado, tendrás que hacer:

$x=\sqrt{f(a)} , x=-\sqrt{f(a)}$

que te da: $x=\sqrt{49} , x =-\sqrt{49}$

Entonces:

$\sqrt{49}=7 , -\sqrt{49} = -7$
