Answer:
Step-by-step explanation:
Let 
represent the cost of the torch and 
represent the cost of the battery.
The torch and a battery cost £2.50 altogether.
The torch costs £2.00 more than the battery.
We substitute the second equation into the first equation to get;
£2.50
The price of the battery is £0.25
We express this as a fraction of the total cost which is £2.50 to get;
To the nearest hundredth: 0.17
To the nearest tenth: 0.2
Answer:
-5/7
Step-by-step explanation:
Find the change between the two x values, which is seven
Find the change between the two y values, which is -5
With slopes, the y always goes over the x, making your answer -5/7
Its A (The area of Building C minus the area of Building B equals the area of Building A)
Answer:
slope=∆y/∆x=9+5/-4-3=14/-7=-2
