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
It is negative only when the number itself is negative.
hence, sometimes.
Answer:
measure of exterior angle is 125°
Step-by-step explanation:
measure of exterior angle is equal to sum of measures of opposite interior angles,
so,
exterior angle ( e ) = 75° + 50°
=》e = 125°
