Step-by-step explanation:
Here, we have to find the sum of 2 fractions:
1st fraction: 
2nd fraction: 
Considering the denominator of 1st fraction:

Using factorization method:
can be written as
.

Taking <em>5 common</em> from
and <em>y common</em> from
:

Now taking
common:

can be written as 
Now, calculating the sum:

Taking <em>LCM</em> and solving:

Hence, answer is
.
30 degrees
Angles ACB and CAB are both 75 degrees due to the fact that they are 90 degree angles subtracting the 15 degrees. Then add the two together and subtract from 180.
Answer:
4.2
Step-by-step explanation:
From the problem, the way the spinner is set up could be
red red blue blue green green yellow yellow purple purple
with two sections of each color and 10 total equal sections.
From this we know that 4 out of the 10 sections are red or green.
That means that there is a 4/10 chance of getting a green or a red every time Kevin spins.
Multiply 180 by 4/10 and you get 72.
The spinner will land on red or green about 72 times.
Hope this helps!
