Answer:
Step-by-step explanation:
So the equation is 1/x+1/y=1/7
Multiplying both sides by 7xy, we get
7y+7x=xy
So x+y=xy/7
Or x=-y+xy/7
So x can be:
1,2,3,4,5,6
Answer:
$66 for 6 cars.
Step-by-step explanation:
This is a rather simple problem. To find the answer you must divide 44/4= 11. Now knowing that Chris earns $11 per car if you multiply 11x6= 66 you can find out Chris makes $66 for 6 cars.
If you would like to transform the following phrase into a math expression, you can do it like this:
8 less than a number is no more than 14 and no less than 5
a number ... n
8 less ... - 8
no more than 14 .... < 14
no less than 5 ... > 5
<span><span><span>Now you just have to put this together: 5 < n - 8 < 14
If 5 and 14 are included: 5 <= n - 8 <= 14

Answer:
Which means that this equation is also true: 8/9 > 1/9
Step-by-step explanation:
Is 8/9 less than 1/9? Is 8/9 smaller than 1/9? These are the same questions with one answer.
To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below:
8/9 = 0.889
1/9 = 0.111
Then, we compare the two decimal numbers to get the answer.
0.889 is not less than 0.111.
Therefore, 8/9 is not less than 1/9 and the answer to the question "Is 8/9 less than 1/9?" is no.
