3w +2 =7w
-3w -3w
2=4w
Divide each side by 4
1/2=w
Check your answer:
3 (1/2) + 2 = 7 (1/2)
(3/2) + (4/2) = (7/2)
(7/2) = (7/2)
Hope this helps.

Answer:
la probabilidad es 1/11
Step-by-step explanation:
Hay 4+4+4 = 12 canicas en total en la bolsa.
Pues la posibilidad de sacar una canica azul en el principio es 4/12 o 1/3.
Y luego, no reemplaces la canica, y hay 11 canicas en total.
Por eso la posibilidad de sacar otra canica azul después es 3/11.
Son eventos independientes, y tenemos que multiplicarlos para tener la respuesta.
1/3 * 3/11 = 1/11
Answer:
The diameter is 3 inches
Step-by-step explanation:
If you are calculating a circle, one of the main rules you should know is that the diameter is double the radius. In this case the radius is 1.5 inches long. If you need the diameter, you need to double that figure; in this case the answer is 3 inches
Answer: So, the probability will be

Step-by-step explanation:
Since we have given that
Number of blue balls =30
Number of red balls = 40
Number of white balls = 30
Since there are 100 balls in total ,
As we have given that there is no white ball chosen.
So, only 70 balls are left with us , from which we choose a blue ball
So, the probability will be
