Answer:

20 pounds

Step-by-step explanation:

because 2 1/2 pounds is enough for 1/8 of an acre, you need 2 1/2 pounds times 8 to cover an 1 whole acre (8/8). 8 times 2 1/2 is 20.

Simplify this expression
kompoz [17]
The first step for solving this problem is to know that in order to divide by a fraction,, we must multiply by the reciprocal of that fraction. This will look like the following:
\frac{x+2}{ x^{2} -6x-16} × 9x
Write -6x as a difference.
\frac{x+2}{ x^{2} +2x-8x-16} × 9x
Factor out x from x² + 2x.
\frac{x+2}{ x X (x+2)-8x-16} × 9x
Factor out -8 from -8(x + 2).
\frac{x+2}{ x X (x+2)-8(x+2)} × 9x
Factor out x + 2 from the denominator (bottom) of the expression.
\frac{x+2}{(x+2)X(x-8)} × 9x
Reduce the fraction with x + 2
\frac{1}{x-8} × 9x
Finally,, calculate the product to find your final answer.
\frac{9x}{x-8}
This means that the correct answer to your question is going to be option B.

A volleyball team played five games, the team won by 7 points, lost by 3, lost by 2 , won by 4 and won by 9. What was the mean d
balu736 [363]

The mean of a set of numbers is the average.  In this problem, add all of the numbers together ( negative numbers for the losses) and then divide by the amount of games total.

Here are the numbers we have to use:

+7

-3

-2

+4

+9

the problem would be 7-3-2+4+9=15

Now divide 15 by your total amount of games which would be 5.

15/5=3

The average difference would be 3.  Now a rule in math is to answer a word problem with a sentence.  

The mean difference in scores over the five games played would be 3.

Hope this helps!
