how the position of the decimal point change in a quotient as you divide a number by 10, 100, and 1,000

Answers

Answer 1

Answer: The decimal moves forward as many places as there are zeros when you divide a number by 10, or a multiple of 10.

7 divided by 10= .7
7 divided by 100= .07
7 divided by 1000= .007

Answers

Simple..

you have y which is the cost of the tickets..and you have x which is the number of tickets..

So, you have those points on the graph....find an equation!

Take any of those coordinates..and find the equation of the line...in the form of y=mx+b

(2,10) and (5,25)

Using: $( y_(1)- y_(2) )/( x_(1)- x_(2) )$

$(10-25)/(2-5) = (-15)/(-3) =5$

Thus, you know your slope. m=5

But, remember it's in the form of y=mx+b

So, use any of the coordinates...let's use (2,10)

10=5(2)+b

10=10+b

0=b

Thus, your equation is... y=5x

Thus, your answer.

382 3/10 - 191 87/100=math difficulties please answer this question

Answers

$382(3)/(10)-191(87)/(100)=\ \ \ | make\ a\ common\ denominator\n\n382(30)/(100)-191(87)/(100)=\n\n381(130)/(100)-191(87)/(100)=190(130-87)/(100)=190(43)/(100)\n\nSolution\ is\ 190,43.$

first you need to find a common denominator , which is 100 . so multiply 3/10 by 10 with both the numerator and denominator. So your new equation should be 382 30/100 - 191 87/100. Even though 382 is larger than 191 , 3/100 is still less than 87/100. So what i do is cross out the first/whole number and then add the denominator. so i change it to look like this....

381 130/100 - 191 87/100

this way its still the same fraction but it will be easier to subtract

so first subtract 381 and 191 which equals 190
then subtract the fractions 130/100 - 87/100 which equals 47/100

so your final answer is 190 47/100
