Answer:

The 7 before the decimal in the number 257.76 is ten times greater than the 7 after the decimal

Step-by-step explanation:

The number located one place to the left of the decimal point is called ones.

The number located one place to the right of the decimal point is called tenth.

In this case, the ones is 10 times greater than the tenth because they are numerically equal.

A) $\frac{x(x+4)}{(2x+4)(2x+3)}$
B) 1/4 = 25%
C) 1/8 = 12.5%

Explanation
A) Let x = the number of yellow blocks. Then x+4 = the number of red blocks, and x+x+4=2x+4 is the total number of blocks.

The probability of choosing a red block first would be
$\frac{x+4}{2x+4}$
since there are x+4 red blocks out of 2x+4 total blocks.

The probability of choosing a yellow block after the red block would be
$\frac{x}{2x+4-1}=\frac{x}{2x+3}$
since there are x yellow blocks, and after 1 is chosen, there are 2x+3 total blocks remaining.

This gives the total probability of
$\frac{x+4}{2x+4}\times \frac{x}{2x+3}=\frac{x(x+4)}{(2x+4)(2x+3)}$

B) If there are 6 yellow blocks, there are 6+4=10 red blocks, and 10+6=16 total blocks.
The probability of getting a red block first would be 10/16, and the probability of getting a yellow block after the red block would be 6/15. Together this gives us
10/16(6/15) = 60/240 = 1/4 = 0.25 = 25%

C) If there are 6 yellow blocks, there are 6+4=10 red blocks, and 10+6=16 total blocks.
The probability of getting a yellow block first is 6/16, and the probability of getting a second yellow block after the first one is 5/15. Together this gives us
6/16(5/15) = 30/240 = 1/8 = 0.125 = 12.5%

Answer:

The answer is -5.

Step-by-step explanation:

Step 1: If you want to get the answer easier, you should use the number line way.

Step 2: If you don't know how to use a number line then go backwards from 18 until you have are done counting, for example;

17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, -1, -2, -3, -4, -5.

Since -5 ( negative five ) is the 23 ( twenty-third ) number you counted back from, you are done counting and now you have gotten your answer of -5!

Answer: x= 2.5, y = 10

Step-by-step explanation:

I'm going to assume that these photocopies are proportional in relations to each other.

If they're proportional, you can set up two proportions:

$1) \frac{x}{5} =\frac{3}{6} \\\\2) \frac{5}{y} =\frac{3}{6}$

And cross-multiply:

$1) 6x = 5*3 \\\\2) 3y = 5*6$

Then solved for x and y:

$1) 6x = 15\\x=\frac{15}{6} =\frac{5}{2} =2.5 \\\\2) 3y = 30\\y=\frac{30}{3} =10$
