Answer:
4 sets
Step-by-step explanation:
406 - 278 = 128
1 set = 40
2 sets = 80
3 sets = 120
4 sets = 160
3.2 sets = 128
Answer:
Option B. 7.6
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
where
k is the constant of proportionality
The slope of the linear equation is the same that the constant of proportionality
In this problem we have

so
the slope is 
therefore
The constant of proportionality k is 
Answer:
y = (31/21)x + 5
Step-by-step explanation:
The bird is flying at 5m/s, so
1 sec = 5 m
It flies for 3 mins
3 mins = 3 x 6sec
3 mins = 180 sec
The bird flies for 180 seconds
1 sec = 5 m
180sec = 5 x 180 = 900m
The bird flew 900m in 3 mins (Answer C)
X=the total amount of pounds of peaches bought Y=the total cost....the equation would be y=2x
