Answer:

Her original amount of money can be represented by the variable x

Because we are spending one-fourth of her money, and “of” translate to multiply, we can write 1/4(x), or equivalently we can say 0.25x of her money, if you prefer decimal.

When you say 1/2 of it, this refers to the original amount of money, x, unless the problem wants you to figure how much 1/2 of the remaining amount is. So if the problem is directly asking for 1/2 of it, that would’ve half of x, or 0.5x in decimal.

Remaining was 50 pence, so the original amount minus 1/4 of the amount minus 1/2 the amount equals 50 pence or .50 giving us the equation: x-0.25x-0.5x=.50

Combine like terms on the left, and we have 0.25x=0.50.

Divide by 0.25 on both sides.

We have x equals 2.

So she started with $2. To check this, we ask ourselves does having $2, and spending 1/4 of it and spending 1/2 of it, then result to 50 pence?

Yes it does, because 2–1–0.5 does in fact equal 0.50 (50pence)

Su cantidad original de dinero puede ser representada por la variable x Debido a que estamos gastando una cuarta parte de su dinero, y "de" se traduce para multiplicar, podemos escribir 1/4 (x), o equivalentemente podemos decir 0.25x de su dinero , si lo prefiere decimal. Cuando dices la mitad, esto se refiere a la cantidad original de dinero, x, a menos que el problema quiera que calcules la mitad de la cantidad restante. Entonces, si el problema es pedir directamente la mitad, tendría la mitad de x, o 0.5x en decimal. El restante era 50 centavos, por lo que la cantidad original menos 1/4 de la cantidad menos la mitad de la cantidad es igual a 50 peniques o .50, lo que nos da la ecuación: x-0.25x-0.5x = .50 Combina términos semejantes a la izquierda, y tenemos 0.25x = 0.50 Divide por 0.25 en ambos lados, tenemos x igual a 2. ella empezó con 2 dólares. Para comprobar esto, nos preguntamos si tener 2 dólares y gastar 1/4 de ellos y gastar la mitad de ellos, ¿da como resultado 50 centavos? sí eso

Which is the best description of the equivalency of the two expressions? Expression 1 Expression 2 5 x squared minus 2 x minus 4
lina2011 [118]

Answer:

The correct option is (D).

Step-by-step explanation:

The two expressions are:

\text{Exp}_{1}=5x^{2}-2x-4+6x+3\\\\\text{Exp}_{2}=6x^{2}-6x+6-x^{2}+10x-7

On simplifying both the expressions we get:

\text{Exp}_{1}=5x^{2}+4x-1\\\\\text{Exp}_{2}=5x^{2}+4x-1

Compute the value of both expressions for <em>x</em> = 2 as follows:

\text{Exp}_{1}=5(2)^{2}+4(2)-1=27\\\\\text{Exp}_{2}=5(2)^{2}+4(2)-1=27

The value of both expressions are same for <em>x</em> = 2.

Thus, the correct option is:

"They are equivalent because when x = 2, the two expressions have the same value."

Help!!!<br> What is the equation of of the line that represents your initial climb?
Juliette [100K]

Answer:

y = 3x

Step-by-step explanation:

The exact equation for the climb would be y = (x-3)^2 + 9, however, a rough line that represents the climb is y = 3x.

Find the slope between (0, 0) and (3, 9) and we get m = 3. Plug it into y-int form and you get the line.
