Answer:

7.68h

38.4 + 7.68h

Step-by-step explanation:

Earnings per hour = $7.68

This week Kaley worked 5 more hours than Tom in overtime

h = number of hours Tom worked.

Tom's total earnings for the week = earnings per hour × number of hours

= $7.68 × h

= 7.68h

Tom's total earnings for the week = 7.68h

Kayley's total earnings for the week = earnings per hour × number of hours

He works 5 hours more than Tom in overtime.

Tom = h

Kayley = 5 + h

Kayley's total earnings for the week = earnings per hour × number of hours

= (7.68) × (5 + h)

= 38.4 + 7.68h

Kayley's total earnings for the week =

38.4 + 7.68h

Is 3x = x + 8 true?​
ANEK [815]

Answer:

So 3x = x +8 is your equation

We adjust the equation to isolate the x and we end up with 2x = 8

We have to isolate the x even more to turn it into x = 4.

So our final answer is x = 4

Durante un mes, tres grupos de quinto grado recolectaron basura para reciclar. El grupo A recolecto 45,765 libras; el grupo B, 6
choli [55]

Answer:

1) Los tres grupos recolectaron un total de 145,738 libras.

2) El grupo B recolectó 27,785 libras más que el grupo C.

3) Los grupos A y C recolectaron 17,980 libras más que el grupo B.

4) Al grupo C le falta 9,671 libras para recolectar lo mismo que el grupo A.

Step-by-step explanation:

A continuación, procedemos a responder cada pregunta:

1) <em>¿Cuántas libras recolectaron en total?</em>

Se obtiene al sumar las cantidades recicladas por cada grupo:

m_{T} = m_{A}+m_{B}+m_{C} (Ec. 1)

Donde:

m_{A}, m_{B}, m_{C} - Cantidades recolectadas por cada equipo, medidas en libras.

m_{T} - Cantidad total recolectada, medida en libras.

Si conocemos que m_{A} = 45,765\,lb, m_{B} = 63,879\,lb y m_{C} = 36,094\,lb, entonces la cantidad total recolectada es:

m_{T} = 45,765\,lb + 63,879\,lb + 36,094\,lb

m_{T} = 145,738\,lb

Los tres grupos recolectaron un total de 145,738 libras.

2) <em>¿Cuántas libras más recolecto el grupo B que el grupo C?</em>

Esta cantidad se obtiene mediante la siguiente diferencia:

m_{B/C} = m_{B}-m_{C} (Ec. 2)

Donde m_{B/C} es la diferencia entre las masas B y C, medida en libras.

Si tenemos que m_{B} = 63,879\,lb y m_{C} = 36,094\,lb, entonces la diferencia de masas es:

m_{B/C} = 63,879\,lb-36,094\,lb

m_{B/C} = 27,785\,lb

El grupo B recolectó 27,785 libras más que el grupo C.

3) <em>¿Cuántas libras más recolectaron los grupos A y C que el B?</em>

Esta cantidad se obtiene mediante la siguiente diferencia:

m_{A+C/B} = m_{A}+m_{C}-m_{B} (Ec. 3)

Donde m_{A+C/B} es la diferencia entre la suma de masas A y C y la masa B, medida en libras.

Si conocemos que m_{A} = 45,765\,lb, m_{B} = 63,879\,lb y m_{C} = 36,094\,lb, entonces la cantidad total recolectada es:

m_{A+C/B} = 45,765\,lb + 36,094\,lb -63,879\,lb

m_{A+C/B} = 17,980\,lb

Los grupos A y C recolectaron 17,980 libras más que el grupo B.

4) <em>¿Cuántas libras le faltaron al grupo C para recolectar las mismas libras que el grupo A?</em>

Esta cantidad se obtiene mediante la siguiente diferencia:

m_{A/C} = m_{A}-m_{C} (Ec. 4)

Donde m_{A/C} es la diferencia entre las masas A y C.

Si tenemos que m_{A} = 45,765\,lb y  m_{C} = 36,094\,lb, entonces la diferencia de masas es:

m_{A/C} = 45,765\,lb-36,094\,lb

m_{A/C} = 9,671\,lb

Al grupo C le falta 9,671 libras para recolectar lo mismo que el grupo A.
