So its going to equal a fraction.

To convert let x equal the repeating decimal (0.1515... it would usually have a line on top of it but I cant type it)

Then examine the number see what place it is in then add another place (in this case it is in the 10000ths place) so multiply it but 10000x

so it would look like: 10000x = 0.1515

then you will move the decimal in to a whole numbers place (0.1515 to 1515.1515

then subtract the decimal 1515.1515- .1515= 1515.

dont forget to subtract from both sides so subtract the 10000x too. (999.515)

then write as fraction form 1515/9999

7(x-2)=28 Can somebody help me and show the steps?

Since the 7 is in front of the parentheses you must multiply it by everything inside the parentheses. 7 times X is 7X and 7 times -2 is -14. Then you need to make the X be by itself on one side, to do that you have to add 14 to -14 to make it disappear, and also add 14 to the other side, to 28. Then you divide both sides by 7 to make X be by itself.

7(x-2)=28
7X-14=28
7x=42
X=6

Part A: Clancey and Ethan are starting new books. So far, Clancey has read 1/4 of his book, which has 240 total pages and Ethan

Nonamiya [84]

In order to find who has read more pages, let's find the number of pages read by each one.

The number of pages read by Clancey is:

$\frac{1}{4}\cdot240=\frac{240}{4}=60$

The number of pages read by Ethan is:

$\frac{2}{5}\cdot170=\frac{340}{5}=68$

So Ethan read more pages.

The combined number of pages in both books is 240 + 170 = 410.

The combined number of pages read is 60 + 68 = 128

So the fraction is:

$\frac{128}{410}=\frac{64}{205}$

Julio says, "If you subtract 19 from my number and multiply the difference by - 7, the result is - 28." What is Julio's number?

Answer:

23

Step-by-step explanation:

Basically I did it backwards & opposites:

-28 divided by -7 = 4

4 + 19 = 23

I checked btw and it worked.

A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. how far will it travel in 21 minutes? in 1 hour?

GaryK [48]

Answer:

Step-by-step explanation:

1¾ miles/(2⅓ minutes) = (7/4 miles)/(7/3 minutes) = ¾ mile/minute

21 minutes × ¾ mile/minute = 15.75 miles

60 minutes × ¾ mile/minute = 45 miles
