Carla trabaja en el área de compras de una empresa que tiene 8 sucursales a lo largo de Chile. A pedido de su jefe necesita comp

rar los siguientes ítems: lápices, carpetas, corcheteras, destacadores, tacos de notas adhesivas y plumones. Cada sucursal necesita 21 lápices, 8 carpetas, 3 corcheteras, 10 destacadores, 6 tacos de notas adhesivas y 9 plumones. Si el precio de cada lápiz es de x pesos, el de cada carpeta es de y pesos, el de cada corchetera es de z pesos, el de cada destacador es el doble de cada carpeta, el de cada taco de notas adhesivas es el doble del precio de cada lápiz y el precio de cada plumón es el triple del precio de cada lápiz. Indique cuál es el gasto total en que Carla incurrirá.

Answer:

Los gastos totales en los que incurre Carla = (36x + 28y + 3z) pesos

Step-by-step explanation:

A partir de la pregunta, a continuación se proporciona la cantidad de elementos necesarios:

21 lápices, 8 carpetas, 3 broches, 10 resaltadores, 6 blocs de notas adhesivas y 9 rotuladores.

Los precios de cada artículo se dan a continuación

Precio de cada lápiz = x pesos

Precio de cada carpeta = y pesos

Precio de cada broche = z pesos

El precio de cada resaltador es el doble que el de cada carpeta

= 2 × y pesos

= 2y pesos

El precio de cada barra de notas adhesivas es el doble del precio de cada lápiz

= 2 × x pesos

= 2x pesos

El precio de cada marcador (bolígrafo) es el triple del precio de cada lápiz.

= 3 × x pesos

= 3x pesos

Indique el gasto total en el que incurrirá Carla.

Los gastos totales en los que incurrirá Carla =

(21 × x pesos) + (8 × y pesos) + (3 × z pesos) + (10 × 2y pesos) + (6 × x pesos) + (9 × x pesos)

= (21x + 8y + 3z + 20y + 6x + 9x) pesos

Recopilar términos similares

= (21x + 6x + 9x + 8y + 20y + 3z) pesos

= (36x + 28y + 3z) pesos

Por lo tanto, los gastos totales en los que incurre Carla = (36x + 28y + 3z) pesos

During a scuba dive, Lainey descended to a point 23 feet below the ocean surface. She continued her

abruzzese [7]

t (23) ≤ 97 - 23

The minus 23 at the back represents the feet she already descended before what the question wants us to calculate

≤ is used instead of < because it states more than, not "equal or more than" (meaning 97 sharp is fine)

Last Question...Please help if you can...(25 points if you answer this)

Answer:

Annie- 17 hours, Brian- 3 hours

Step-by-step explanation:

Let the number of hours Annie travelled be a, and same of Brian be b

<u>Then we have</u>

a + b = 20
a = 5b + 2

<u>Substituting a in the first equation</u>

5b + 2 + b = 20
6b = 20 - 2
6b = 18
b = 3

<u>Then finding a</u>

a = 20 - 3 = 17

<u>So the answer is:</u>

Annie- 17 hours, Brian- 3 hours

Rewrite the expression $6j^2 - 4j 12$ in the form $c(j p)^2 q$, where $c$, $p$, and $q$ are constants. What is $\frac{q}{p}$

solniwko [45]

$Rewrite the expression 6j^2 - 4j + 12$ in the form $c(j + p)^2 + q$, where $c$, $p$, and $q$ are constants. What is $\frac{q}{p}$$

The ratio of $\frac{q}{p}$ = - 34

How to solve such questions?

Such Questions can be easily solved just by some Algebraic manipulations and simplifications. We just try to make our expression in the form which question asks us. This is the best method to solve such questions as it will definitely lead us to correct answers. One such method is completing the square method.

Completing the square is a method that is used for converting a quadratic expression of the form $ax^{2} + bx + c$ to the vertex form

$a(x - h)^{2} + k$ . The most common application of completing the square is in solving a quadratic equation. This can be done by rearranging the expression obtained after completing the square: $a(x + m)^{2} + n$ , such that the left side is a perfect square trinomial

$6j^2 - 4j +12$

= $6(j^2 - \frac{2}{3} j )+12$

= $$6(j^2 - \frac{2}{3} j + \frac{1}{9} )+\frac{102}{9}$ (Completing Square method)

= $6( j- \frac{1}{3} )^{2} + \frac{34}{3}$

On comparing with the given equation we get

p = - $\frac{1}{3}$ and q = $\frac{34}{3}$

∴ $\frac{q}{p}$ = $\frac{\frac{34}{3} }{\frac{-1}{3} }$

= - 34

How do you add add fraction with a different denominator?

kenny6666 [7]

Find the LCM (least common multiple) of the denominators, and use that as the denominator for the two fractions.

Ex.

$\frac{3}{4} +\frac{2}{3}$

LCM (3, 4) is 12

$\frac{9}{12} +\frac{8}{12}$

= $\frac{17}{12}$
