The answer is (0,0) because it is the same differences as the others
Let x= the time each one paints at the same time. Painting one whole room means that the output of our equation equals....1.
x/5 = the fraction of the room Matt can paint in x hours.
x/3 = the fraction of the room Elliot can paint in x hours.
Our working equation will be: x/5+x/3 = 1
[solve for x]
[start by finding common denominator] 3x/15 + 5x/15=1
[add together] 8x/15 = 1
[isolate the variable] 8x=15
x=15/8, or 1 7/8 hours. Together, they can paint a room together in 1 7/8 hours. (An hour, 52 minutes, 30 seconds if you divide it all the way out!)
Answer:
B
Step-by-step explanation:
look at where the line reaches on the y-axis
1) exterior angle = sum of interior angles except the neighboring one.
1) 48 + 45 = 93
2)180 - 147 = 33 , 180 - 72 = 108
x = 180 - 108 - 33 = 39
3) 180 - 104= 76
x = 51 + 76 = 127
4) 180 -154 = 26 , 180 - 73= 107
x = 180 - 107 - 26= 47
180 - 110 = 70
x = 180 - 140 = 40
last) 180 - 122 = 58
x = (180 - 58)/2 = 61
Answer:
147 ft²
Step-by-step explanation:
14 x 14 = 196
7 x 7 = 49
196 - 49 = 147
