Answer:
5.1x - 1.49y
Step-by-step explanation:
We need to add or substract like terms.
like terms are the terms that have the same variable, in this case:
3.27x and 1.83x are like terms, and adding them we get:
3.27x + 1.83x = 5.1x (you add only the coefficients and the x stays the same)
we do the same for the terms with 'y':
1.28y and −2.77y are like terms, but in this case we must substract because of the − sign:
1.28y −2.77y = -1.49y
the final answer is the conjunction of the two results that we obtained:
5.1x - 1.49y
The answer is c. 
a. 
(2.2≠5.11) (2.2 is not equal to 5.11)
b. 
or 0.625 (0.625≠5.11) (0.625 is not equal to 5.11)
c. 
(5.11=5.11) (5.11 is equal to 5.11)
Therefore c is the answer
Answer:
104°
Step-by-step explanation:
Step-by-step explanation:
the measurement or extent of something from end to end; the greater of two or the greatest of three dimensions of an object.
The incorrect answer is B.
All you have to do is plug in x to the formulas and see if the are equal.
4x - 2 = 3x + 6
4(8) - 2 = 3(8) + 6
30 = 30
CORRECT
The second is not only not equal, but it is the wrong kind of formula for what you are trying to prove there.
Hope that helps!
