Mathematics

Ad libitum [116K]3 years ago

1) 8(3a+6) = 9(2a-4)

First, we use distributive property on both sides.

Once we do this, we get:

24a + 48 = 18a - 36

Add 36 to each side.

24a + 84 = 18a

Subtract 24a from each side.

84 = -6a

Divide each side by -6

-14 = a

2) 6(2x-8)+3 = 15

Again, we use distributive property:

12x-48+3 = 15

Subtract 3 from each side

12x - 48 = 12

Add 48 to each side

12x = 60

Divide each side by 12

x = 5

3) -5(3x+6) = -3(4m-2)

Distributive property:

-15m - 30 = -12m + 6

Add 30 to each side

-15m = -12m + 36

Add 12m from each side

-3m = 36

Divide each side by -3

m = -12

La empresa González se dedica a la fabricación y venta de mesas para jugar domino. Luego de un estudio, determinaron que el cost
Angelina_Jolie [31]

Answer:

  • Total cost/Costo total: TC=524+6x
  • Slope/pendiente: change in total cost when we produce an additional unit /cambio en el costo total cuando se incrementa la produccion en una unidad.
  • Total cost if 345 tables are made/costo total por elaborar 345 mesas: TC=524+6\times{345}=2594.

Step-by-step explanation:

  • Total cost/Costo total: 524+6x. Total amount of money spent when producing x amount of tables, equals a fixed amount that must be paid and an extra of $6 for every additional table produced./ Cantidad de dinero gastado cuando se produce una cantidad x de mesas, es equivalente a $524 de costos fijos mas $6 adicionales por cada mesa producida.
  • Slope/pendiente: change in total cost when we produce an additional unit. It is the coefficient that is linkes the extra amount of money spent when producing an extra unit of x (tables). /Cambio en el costo total cuando se incrementa la produccion en una unidad. El el coeficiente que vincula el cambio en el costo total con el cambio en las cantidades producidas.
  • Total cost if 345 tables are made/costo total por elaborar 345 mesas: TC=524+6\times{345}=2594. (Is the result of replacing in the equation x=345, which means to evaluate the total costo when we produce 345 tables/Es el resultado de remplazar en la ecuacion x=345, lo que resulta en saber el costo total de producir 345 mesas).

Whoever can answer all of these will get brainless
inn [45]

Firstly, brainly allows 1 question per question. So do not try this again.

Lets make the fractions all like terms.


242/4 - 37/4=205/4. Lets now make this a mixed fraction.
By doing 205/4, we find out that 4 goes in less than 51 times.

1. 51  1/4.

2. 11/2 = 66/12.....so 66/12 - 29/12= 37/12. Make it mixed fraction: 3 1/12.

3. 36/5=72/10.      72/10 - 37/10 = 35/10. As a mixed it is 3 1/2

4. 35/3 - 17/2 can be rewritten by finding their GCM (Greatest Common Multiple). In this case it is 6.

70/6 - 51/6 = 19/6. 3 1/6.
