3 adults and 5 kids.
You can get this by setting up the following system of equations.
x + y = 8 (number of people)
10x + 12y = 86 (cost)
Answer: First answer goes with second graph
Second answer goes with third graph
Third answer goes with first graph :)
Step-by-step explanation:
Answer:
12.5 s
Step-by-step explanation:
If acceleration is constant, speed is proportional to time. To increase the speed by 50 km/h, the car will need an additional time given by ...
t/(50 km/h) = (20 s)/(80 km/h)
t = (20 s)(50/80) . . . . . multiply by 50 km/h
t = 12.5 s
It will take 12.5 more seconds for it to reach a speed of 130 km/h.
The equation of the line that passes through the points (2,1) and (5,-8) is
y = -3x + 7
Answer:
320
Step-by-step explanation:
go backwards, 75 + 45 = 120
120 * 5/3 = 200
200+40 = 240
240 *4/3 = 320
