Answer:
450 cubic meters
Step-by-step explanation:
Austin didn't add the 2 prisms, he multiplied the 1st prism and kept it as the answer.
60 litres
To obtain the greatest volume of the tin, we calculate the highest common factor of both 120 and 80
Factors of :
80 : 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
The highest common factor is 60.
Hence, the greatest volume of the tin would be 60 litres
x≤3
3x≤5+4
3x≤9
8y = -6
Simply add the equations as you would numbers.
The 'x's cancel each other out. The 'y's add together as normal numbers.
9 + (-15) = -6
Hope that this helps!
