It is different because to find out the answer, change all denominators to 10, since the LCD is 10.
6/10-5/10=1/10
6/10-6/10=0/10
1/10 is not equal to 0/10
Answer:
6/10 is equivalent to 3/5, so is 9/15.
Step-by-step explanation:
Answer:
18 years
Step-by-step explanation:
let catrinas age be c
3(c/2)+3=12
3c/6=9
3c=54
c=18
It should just be 2x-5= 125
Then add 5 to both sides
2x= 130
Divide by 2
X= 65
<h3>The sum expressed in sigma notation is:</h3>

<u><em>Solution:</em></u>
Given that,
11 + 17 + 23 + 29 + 35 + 41
We have to express the sum in sigma notation
Analyse the series
5 + 6(1) = 11
5 + 6(2) = 17
5 + 6(3) = 5 + 18 = 23
5 + 6(4) = 5 + 24 = 29
5 + 6(5) = 5 + 30 = 35
5 + 6(6) = 5 + 36 = 41
<em><u>Thus the series goes on like this:</u></em>
5 + 6(n) , where n = 1 to 6
<em><u>This can be expressed in sigma notation as:</u></em>

<em><u>We can expand the sigma notation and verify the results</u></em>
