A - avocados, G - grapes, K - kiwis.
We know that: A = 3G, K = A - 0.75
So: G = A / 3
A + G + K = 16.75
A + A/3 + A - 0.75 = 16.75
7/3 A = 16.75 + 0.75
7/3 A = 17.50
A = 17.50 : 7/3
A = $7.50
G = 7.50 : 3 = $2.50
K = 7.50 - 0.75 = $6.75
Answer:
Prices of the fruits are A = $7.50, G = $2.50 and K = $6.75.
The system of equation
y=8x and y=2x
To solve this using graphical method
The solution is the point of intersection of the two-lines
As shown from the graph above, the solution is (0,0)
Answer:
The net force that the object has is 6000 newtons
Step-by-step explanation:
The net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object
F = m a, where
- m is the mass of the object in kilogram
- a is the acceleration that the object accelerates with it in meter per square second
A cannonball begins accelerating at 40 m/s²
∴ The acceleration is 40 meters per square second
∴ a = 40 m/s²
∵ The mass of the cannonball is 150 kilograms
∴ m = 150 kg
- Substitute a and m in the rule of the force
∵ F = m a
∴ F = 150(40)
∴ F = 6000 newtons
The net force that the object has is 6000 newtons
