Answer:

Length equals 14

Step-by-step explanation:

This problem can be written out as 2 equations

Since we know the perimeter (P) is 48, we can use the formula 2l+2w=P and get 2l+2w=48.

Then we can take the other equation, w+4=l (which I got from the second sentence), and substitute it for l in the equation.

This can be written out as- 2(w+4) + 2w=48

Then we distribute and get 2w + 2w + 8 = 48, simplifying to 4w + 8= 48

We then subtract 8 from 48 and get 4w=40, dividing 40 by 4 to get w=10.

then, we add 4 to w to get 14.

Una empresa fabrica dos productos, X y Y. Cada cantidad del articulo X producida requiere dos horas de trabajo en una taladrador
Zarrin [17]

Answer:

la respuesta esta abajo

Step-by-step explanation:

a) Sea x el número del artículo x mientras que y representa el número del artículo y.

Dado que cada cantidad de artículo x requiere 2 horas de trabajo de perforación, mientras que cada cantidad de artículo y requiere 5 horas de trabajo de perforación. Hay un máximo de 40 horas disponibles, por tanto el modelo se da como:

2x + 5y ≤ 40

b) La trama se trazó utilizando la herramienta gráfica en línea de geogebra.

c) Para 10 unidades de X y 5 unidades de y:

2 (10) + 5 (5) = 45> 40

Por lo tanto, esto no sería posible porque requerirá 45 horas de perforación, lo que es más que el máximo de 40 horas disponibles.

I need help on this question plz
olasank [31]

It is convenient to follow directions. Create a chart with activities as column headings. Since the data is divided according to gender, you would put gender on the row headings. Fill in the given numbers (black), and make the totals come out (blue).

The numbers in the row total column are exactly that: the total of the numbers in the row. (A spreadsheet can do the actual addition or subtraction for you.)
