A number has the same digit in its hundreds place and its hundredths place. How many times greater is is the value of the digit in the hundreds place than the value of the digit in the hundredths place?A. 100,00

B. 100

C. 1,000

D. 10,000

Answers

Answer: D. 10,000

Step-by-step explanation:

Given: A number has the same digit in its hundreds place and its hundredths place.

Let the digit be '1'.

Then , the place value of number's hundreds place = 100

The place value of number's hundredths place = 0.01

Now, the number of times the value of the digit in the hundreds place is greater than the value of the digit in the hundredths place is given by :-

$(100)/(0.01)=(100*100)/(1)=10,000$ [Insert comma after 3 digits from the right]

Hence, the the value of the digit in the hundreds place is 10,000 times greater than the value of the digit in the hundredths place.

Say the number is, IDK, 333.33
The hundredths equals 0.03
The hundreds equals 300
You can divide 300 by 0.3
You get 10000
10000 is the answer

{y=3x+7 & y=5x-7

Answers

$\left\{\begin{array}{ccc}y=3x+7\ny=5x-7\end{array}\right\n\nsubstitute:\n\n5x-7=3x+7\n5x-3x=7+7\n2x=14\ \ \ \ /:2\nx=7\n\ny=3\cdot7+7=21+7=28\n\nAnswer:x=7\ and\ y=28.$

y = 3x + 7
y = 5x-7

Now, we know that y = y

thus,

3x + 7 = 5x-7
3x - 5x = -7 -7

= -2x = -14

thus, -x = -14/-2

thus, x = 7.

Substituting for y,

y = 3x + 7
= 3 x 7 + 7

= 28.

Thus, x = 7, y =28

How can I solve 8 5/6 - 2 1/3=

Answers

You turn 8 5/6 and 2 1/3 into improper fractions (8 5/6 becomes 53/6 and 2 1/3 becomes 7/3)

Then you take 53/6 and 7/3 and find a common denominator which is 6
Then you multiply 7x2 and 3x2 which equals to 14/6

53/6 - 14/6 is 39/6
You can leave it as 39/6 or change it into a mixed number, if you make it a mixed number then you would get 6 3/6 which is equivalent to 6 1/2.

There is another method than what the other user has pointed out (both are valid and are up to personal preference as to which are better)

For this method you need to make sure that both the denominators are the same.

(See attached image)

I hope this makes sense!

As a summary; you must make sure that both denominators of the fractions are the same. Whatever number you multiply by for the denominator, use also for the numerator.
