Step-by-step explanation:
Slopes are generally the ratio of rise(vertical difference) to fall (horizontal difference) for set of points lying on a straight line
Positive slopes show a positive relationship between the two things we are considering while a negative one shows otherwise
They are the same in the sense that they actually represent a constant change between the coordinates of the points in the relationship we are considering.
They are different in the sense that while one represents a positive change, whereby both axes move in the same direction ( rise at same rate, fall at same rate) , the second represent a relationship in which they move in opposite directions. While one falls, the other rises and while the other rises, the second one falls which indicates an opposing movement type between the two
Answer:
125 adults
175 children
Step-by-step explanation:
3900=8c+20a
300=c+a
c=300-a
substitute
3900=8(300-a)+20a
reduce
3900=2400-8a+20a
1500=12a
a=125 adults
substitute for a
c=300-a
c=300-125
c=175 children
1) 70
2) 110
3) 70
because 110 is equivalent to angle 2. angle 1 and 3 are also equivalent so you add 110 + 110 which equals 220 and subtract 360-220 which equals 140 and divide by 2 to get angles 1 and 3.
