Which value of x would make ?<br><br> 1<br> 6<br> 8<br> 10
Liono4ka [1.6K]

Answer:

x=8\ in

Step-by-step explanation:

we know that

If NO is parallel to KJ

then

Triangles LNO and LKJ are similar by AA Similarity Postulate

Remember that

If two figures are similar, then the ratio of its corresponding sides is equal

so

\frac{LO}{LJ}=\frac{LN}{LK}

substitute the values

\frac{x-4}{x-4+x}=\frac{x-3}{x-3+x+2}

\frac{x-4}{2x-4}=\frac{x-3}{2x-1}\\ \\(x-4)(2x-1)=(x-3)(2x-4)\\ \\2x^{2}-x-8x+4=2x^{2}-4x-6x+12\\ \\-9x+4=-10x+12\\ \\10x-9x=12-4\\ \\x=8\ in

En un libro de cocina se recomienda hornear un pavo a baja temperatura 3/4 de hora por cada libra y cuarto
german

Usando proporciones, hay que se debe hornear un pavo de 7 y 1/2 libras en 4.5 horas.

<h3>Lo que es una proporción?</h3>
  • Una proporción es una fracción de la cantidad total, y las medidas se relacionan usando una regla de tres.
  • En este problema, para cada libra y quarto de peso, o sea 1\frac{1}{4} = 1 + \frac{1}{4} = \frac{5}{4} de libras, el tiempo en horas es de \frac{3}{4}. Qual el tiempo para un peso en libras de 7\frac{1}{2} = 7 + \frac{1}{2} = \frac{15}{2}?

La <em>regla de tres</em> es:

Peso(libras) - Tiempo(horas)

\frac{5}{4} - \frac{3}{4}

\frac{15}{2} - x

Aplicando multiplicación cruzada:

\frac{5}{4}x = \frac{45}{8}

x = \frac{45 \times 4}{5 \times 8}

x = \frac{9}{2}

x = 4.5

Se debe hornear un pavo de 7 y 1/2 libras en 4.5 horas.
