Answer: 1 3/10a+19
Step-by-step explanation:
Ok so first you have to open the parenthesis. Since the sign to the left of both the parenthesis is positive we can just normally open the parenthesis .
We get: 1/2a+12+4/5a+7
We need to convert the denominators of 1/2a and 4/5a so we can add them together
1/2a=5/10a
4/5a=8/10a
Now we can add the a variables together.
5/10a+12+8/10a+7=
13/10a+12+7
Then add 12 and 7 together:
13/10a+19 = 1 3/10a+19
Keep in mind: If the sign to the left of the leftmost parenthesis is negative then the sign inside the parenthesis is negative.
For example when opening this parenthesis: (2+3/x<u>)-(2+3x)</u> the sign is negative so the opening parenthesis is -2-3x.
The simplest form is x-9! :)
Hope it helped!
Answer : Second Option is correct.
Explanation :
Since we have given in the figure ,
AE=12 units
AD=9 units
EB=4 units
DC=x units
By using the BPT theorem, which states that
"If a line is drawn parallel to one side of a triangle in distinct point , the other sides are divided in the same ratio."
So, here we have a ΔABC,
in which DE║BC as shown in the figure ,
so, by using the BPT we get,
Hence, length of DC = 3 units .

Answer:
2/5
Step-by-step explanation:
The multiplicative inverse of 2.5 is 2/5 or 0.4. We have a rule that states that the the multiplicative inverse of a fraction a/b is b/a.
