Answer:
each side is 31cm
Step-by-step explanation:
91/3=31
31+31+31=93
10
Therefore, the greatest common factor of 30 and 50 is 10.
Answer:
x=12
Step-by-step explanation:
The three angles add to a straight line which is 180 degrees
20 + 6x-2 + 90 = 180
Combine like terms
108 + 6x = 180
Subtract 108 from each side
108+6x-108 = 180-108
6x =72
Divide each side by 6
6x/6 = 72/6
x=12
Y=25x is proportional. Unit rate is 25
The other 2 aren't because they have a y-intercept and don't cross the orgin
