Step-by-step explanation:
First sequence with common difference:
8-x=y-8
Second sequence:
20-y=y-x
Solving two simultaneous equations:
x=16-y
20-y=y-16+y
y=12
x=4
teacher has 0.4 L of sea water , it means 0.4*1000 ml = 400 ml of sea water , she has.
Now every student has 5 ml spoon with them and there are a total of 20 students.
The teacher has asked every student to put 2 spoons of seawater into their container .
Now 1 spoon = 5ml
2 spoon = 10 ml
22 students are there it means
there are 44 spoons.
44 spoons = 44* 5 ml = 220 ml
It means Student put 220 ml seawater in total
