The answer is B It basically just expressing the 2×(6+9)
The expression 2 × (6 + 9) = (2 × 6) + (2 × 9) represents the distributive property option (B) is correct.
What is distributive property?The distributive property is the property that expresses the distributive law of algebraic multiplication. Similarly, in polynomial expression we can use the distributive property, for example we can write a(c+b) in the form of (ac+bc).
We have an expression:
= 2 × (6 + 9)
After applying the distributive property:
= (2 × 6) + (2 × 9)
= (12) + (18)
= 30
Thus, the expression 2 × (6 + 9) = (2 × 6) + (2 × 9) represents the distributive property option (B) is correct.

Answer:
w= 8/7
Step-by-step explanation:
1. divide the numbers
[tex]12w-1*10=6-2w[/tex]
2. multiply the numbers
[tex]12-10=6-2w[/tex]
3. rearrange terms
[tex]12-10=-2w+6[/tex]
4. add 10 to both sides of the equation
[tex]12w-10+1-=-2w+6+10[/tex]
5. simplify
[tex]12w=-2w+16[/tex]
6. add 2w to both sides of the equation
[tex]12w+2w=-2w+16+2w[/tex]
7. simplify
[tex]14w=16[/tex]
8.divide both sides of the equation by the same term
14w/14 = 16/14
9. simplify
w = 8/7
Answer:
[tex]w = 2[/tex]
Step-by-step explanation:
[tex] \frac{(12w - 20)}{2} = 6 - 2w[/tex]
[tex]6w + \frac{ - 20}{2} = 6 - 2w[/tex]
[tex]6w + \frac{( - 10.2)}{(1.2)} = 6 - 2w[/tex]
[tex]6w + 10 = 6 - 2w[/tex]
[tex]6w - 10 + 2w = 6 - 2w + 2w[/tex]
[tex]6w + 2w - 10 = 6 - 2w + 2w[/tex]
[tex]8w - 10 = 6 - 2w + 2w[/tex]
[tex]8w - 10 = - 2w + 2w + 6[/tex]
[tex]8w - 10 = 6[/tex]
[tex]8w - 10 + 10 = 6 + 10[/tex]
[tex]8w = 6 + 10[/tex]
[tex]8w = 16[/tex]
[tex] \frac{8w}{8} = \frac{16}{8} [/tex]
[tex]w = \frac{16}{8} [/tex]
[tex]w = \frac{2.8}{1.8} [/tex]
[tex]w = 2[/tex]

A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in 25 minutes? In 1 hour?
Answer: They would travel 17.25 miles in 23 minutes and 45 miles in 1 hour.
Step-by-step explanation:
If you divide 1 3/4 by 2 1/3 you get. 0.75 which is how far the car will travel each minute and then you can just multiply that number by however many minutes there are.
Un comerciante de ganado compro cierto número de novillos, todos al mismo precio, por un total de 1 440 000 colones. De estos, vendió 20 a 22000 colones cada uno. Si desea obtener una ganancia de 200 000 colones debe vender cada uno de los restantes novillos en 2000 más que el precio en que los compro. ¿Cuántos novillos compro y cuanto le costó cada uno?
Queremos encontrar y resolver un sistema de ecuaciones para encontrar el número de novillos comprados y el valor de cada uno.
Encontramos que las soluciones son:
Precio = 12,820.5 colones.Número = 112La información que tenemos es:
El comerciante compro un dado número de novillos, digamos N.
El precio total fue de 1,440,000 colones.
Entonces si el precio de cada novillo es P, tenemos que:
N*P = 1,440,000
Sabemos que vendio 20 a 22,000 colones cada uno, es decir, obtuvo:
20*22,000 colones = 440,000 colones.
Es decir, de momento se tiene una perdida de:
1,440,000 - 440,000 = 1,000,000 colones.
Sí quiere obtener una ganancia de 200,000 colones, debe vender los (N - 20) novillos restantes a 2,000 colones más que P.
De esto planteamos la ecuación:
(N - 20)*(P + 2,000)= 1,000,000 colones + 200,000 colones = 1,200,000 colones.
Entonces tenemos el sistema de ecuaciones:
N*P = 1,440,000
(N - 20)*(P + 2,000) = 1,200,000
Para resolver esto comenzamos por aislar una de las variables en la primera ecuación, aislaremos N
N = (1,440,000)/P
Ahora reemplazamos esto en la otra ecuación:
(N - 20)*(P + 2,000) = 1,200,000
( (1,440,000)/P - 20)*(P + 2,000) = 1,200,000
Ahora debemos resolver esto para P.
1,440,000 - 20*P - 20*2,000 + 2,000*(1,440,000)/P = 1,200,000
- 20*P + 2,000*(1,440,000)/P = -180,000
Multiplicando ambos lados por P, obtenemos:
-20*P^2 + 2,880,000,000 = -180,000*P
Reescribimos esto como una ecuación cuadratica:
-20*P^2 + 2,880,000,000 + 180,000*P = 0
Y podemos resolver esto usando la formula de Bhaskara.
[tex]P = \frac{-180,000 \pm \sqrt{(180,000)^2 - 4*(-20)*(2,880,000,000)} }{2*-20} \\\\P = \frac{-180,000 \pm 512,640.22471 }{-40}[/tex]
Solo nos interesa la solución positiva, que es:
[tex]P = = \frac{-180,000 - 512,640.22471 }{-40} = 12,820.5[/tex]
Es decir, cada novillo le costó 12,820.5 colones.
y sabemos que:
N = 1,440,000/P = 1,440,000/12,820.5 = 112.3
Redondeamos al proximo numero entero, que es 112, donde ese 0.3 debe venir de algun error de redondeo (o más probablemente a un problema mal planteado).

Answer:
1.45 x 10^2
Step-by-step explanation:
In scientific notation, you get the number down to 1 digit before the decimal place and all the rest after it, then multiply by 10 raised to a power in order to get it back to the original. An easy way to do it is to count the number of times you moved the decimal and remember which direction you did it. The number is the power (in this case 2) and the direction tells you if it's positive or negative (in this case it was to the left, so it's positive two.)
In simpler terms, slide the decimal to the right two places and make it 1.45, then multiply it by 10^2 (which is 100) to make it equal to 145. This leaves you with 1.45 x 10^2.

Answer:
a) f(0)=3*0+1 =0+1= 1
b)f(2)=3*2+1=6+1=7
c)f(-2)=3*(-2)+1=-6+1=-5
Answer:
Step-by-step explanation:
f(x) = 3x+1
f(0) = 3x + 1
f(0) = 3*0+1
f(0) = 0+1
f(0) = 1
f(2) = 3x+1
f(2) = 3*2+1
f(2) = 6+1
f(2) = 7
f(-2) =3x+1
f(-2) =3*-2+1
f(-2) = -6+1
f(-2) = -5
f(-2) =
