Ok so to find the answer to this you have to make both fractions have the same denominator.
To find the LCD (Least common denominator) follow these steps:
*Think: what number can be divided by both 9 and 5?
The answer is: 45 (shortcut way is to multiply both denominators by each other ie: 9 x 5)
Now make the numerators match:
For -3/5, the denominator (5) is multiplied by 9 to get 45, so the numerator (-3) has to also be multiplied by 9.
You get: -27/45
For 4/9, the denominator (9) is multiplied by 5 to get 45, so the numerator (4) has to also be multiplied by 5.
You get: 20/45
Now the problem looks like this:
-27/45 + 20/45
**Be sure to remember there is a negative sign!
Now we just add the numerators:
-27 + 20 = -7
(If you have trouble doing that remember that you can just subtract the positive number from the negative ie: 27-20 and then just re-add the negative sign)
Then just re-add the denominator:
-7/45
This cannot be simplified so this is the final answer!
2/4 + 18/5 + 28/10 + 5/20 = 143/20 (total)
143/20 ÷ 4 = 1 63/80
Ans: 1 63/80 or 1.7875

Answer:
a) Degree of E = 2
b) Even vertices: B, C, E
Odd vertices : A, D
c) Vertices A, C, and E are adjacent to D
Step-by-step explanation:
a) The degree of a vertex is given by the number of segments that end there, so in the case of vertex E, there are only two segments that connect it, therefore its degree is 2
b) Following the same idea of degree of a vertex, we can find the number of segments that end on each one of the 5 vertices shown and assign to them their degree:
A (3), B (2), C (4), D (3), E (2)
Therefore the odd vertices are: A and D (both of degree 3)
The even vertices are: B, E (both of degree 2, and C (degree 4)
c) the vertices adjacent to vertex D are those connected directly to it via a segment: that is, vertices A, C, and E
Answer:
0.4906 or 49.06%

<em>Missing Information:</em> I have attached the missing table showing the data obtained from the poll taken from respondents
Step-by-step explanation:
Using the data,
the number of people who do not think there will be an impact of global warming during their lifetime = 131
Number of People who think there will be impact = 134
Number of People who are unsure = 2
Total no. of people = 131 +134 +2 = 267
Probability that respondent 18-29 years age thinks global warming won't pose a threat during his/her lifetime = P
Probability = P = 
Probability = P = 
= 0.4906 or 49.06 %
