Use a calculator solved :)))
Step-by-step explanation:
Answer:
A)
Step-by-step explanation:
Let me know if anything is unclear :)
x/.75=x-56/0.4
0.4x=.75x-42
-0.35x=-42
x=120
I set up a proportion in which x=the tank when it is 3/4 full. When the tank is 3/4 full, solving the proportion tells us the x=120 litres. 120/3=40, and 120+40 is 160, showing that a tank completely full would indeed hold 160 litres.
Hope this helps!
I’m pretty sure the answer would be A
