Answer:
Step-by-step explanation:
20. First find the values of the numbers being added.
These numbers have a common denominator, so you can add the numerators
27 + 25 = 52
so the number comes out to 
to simplify, divide the numerator and denominator by 4.
So the final fraction becomes 
However the question doesn't have this answer and now I am confused. I assumed that the expression was 
but the picture is a little bit blurry and I have bad eyesight so let me know if it is not. I'm too tired to delete this so next problem.
21.
4x + 8x + 7 + 4
Combine the like terms to get the expression
12x + 11 the answer is c.
40/100=4/10=2/5 hence 2/5=40/100
Answer:
The answer is B.36
Step-by-step explanation:
12+12+12=36
12 3x is 3x12
so 3x12 is 36
You cut off the edge. No matter; we have two pairs of congruent angles, and included side AC is congruent to itself, so we have everything we need to invoke
Answer: ASA, the Angle-Side-Angle triangle congruent theorem
Step-by-step explanation:
if we know that percentage means out of 100%
p= percent(%)
our equation must be p% = 
so, p%=
