Three tanks, A, B and C are used to store oil.
Tank A contains n litres of oil. Tank B contains (n + 150) litres of oil.
Tank C is empty.
Oil is pumped from tank A and from tank B into tank C so that
all three tanks contain the same amount of oil.
500 litres of oil are pumped from tank A into tank C.
Work out the value of n.

soln

A= n

B= 150

C=?

now,

A+B+C= 500

n+150+c= 500

n+c= 500-150

n+c= 350

2n+c = 350

n+c= 350/2

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
