Question

A tank with some sand has a mass of 4050 g. Another similar tank with some water has a mass of 2550 g. The mass of the sand is 3 times the mass of the water. What is the mass of the empty tank? Pls help me!​

Answer 1

=1800g

Explanation:

T + S=4050

T + W=2550

let s:w be 3t:t

4050-3t=2550-t

collect like terms

-2t= -1500

-2 -2

t=750g

therefore

T= 2550-750

=1800g
