A ton is 2,000 lb , so 2 tons would be 4,000 lb. 4,000+445.5=4,445.5
The two elephants combined weigh 4,445.5 lb.
So first you would have to add $25+$13.50=38.5 then subtract 38.5-2.68=35.82
Answer:
True
Step-by-step explanation:
If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²
c is the largest side and a and b are the two smaller sides of the triangle.
So if this is true then √72² + 154² should be 170:
170² = 72² + 154²
28900 = 5184 + 23716
28900 = 28900
So we have proved using Pythagoras theorem that the triangle is a right angled triangle.

You can get this by setting up the following system of equations.
x + y = 8 (number of people)
10x + 12y = 86 (cost)
