100°+(4y+25)+(3y+20)=180°
100+4y+25+3y+20=180
7y+145=180
7y=35
y=5
100°; 45°; 35°
Elaine's would be because.16 is closer to being a whole than .016
If the signs are alike, and ur adding/subtracting......u add them and keep the same sign
Answer:
(0,1)
Step-by-step explanation:
There are infinite number of (x,y) pairs in a line, so it should be easy to use any value for one of the coordinates (x or y) and find what the other coordinate should be. We can use a simple value that would make our solving easy, for example x = 0. We use this value to replace x in the equation of the line, and solve for y:

Therefore the pair (0,1) is a solution for the given equation.
