ElenaW [278]

Answer:

<em>The flour will last for about 11 days.</em>

Step-by-step explanation:

Suppose, the flour will last for  x days.

She uses 15 pounds of flour each day. So, <u>the total amount of flour used in x days</u> = 15x pounds.

Given that, she has 157.86 pound of flour. So, the equation will be......

15x= 157.86\\ \\ x= \frac{157.86}{15}=10.524 \approx 11

Thus, the flour will last for about 11 days.

pogonyaev

Answer:

24/225

Simplified: 8/75

Step-by-step explanation:

8 + 4 + 3 = 15

Since there are no replacements the denominator will get lower every time a marble is pulled.

First is blue which means,

3/15

The second is white,

8/15

If I'm not wrong you would multiply 3/15 and 8/15 and you get 24/225.

Simplified: 8/75
