Answer:

large tank volume = 6 litres

small tank volume = 3 litres

Step-by-step explanation:

Given that,

The combined volume of 3 large tanks and 2 small tanks is 24 litres.

The combined volume of 2 large tanks and 3 small tanks is 21 litres.

Suppose large tank volume = x

Suppose small tank volume = y

<h2>First Equation </h2>

3x + 2y = 24

<h2>Second Equation </h2>

2x + 3y = 21

Now solve them

3x =24 - 2y

x = (24 -2y) / 3

Put value of x in second equation

2 {(24 -2y) / 3} + 3y = 21

2(8) - 4y/3 +3y = 21

16 - 4y/3 + 3y = 21

3y -4y/3 = 21-16

5y/3 = 5

5y = 15

y = 15/5

y = 3

3x = 24 - 2(3)

3x = 18

x = 6

What are the coordinates of the point on the directed line segment from
Zielflug [23.3K]

Answer:

(- 1, - 3 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n

Then using the Section formula the coordinates of the point are

( \frac{nx_{1}+mx_{2}  }{m+n}, \frac{ny_{1}+my_{2}  }{m+n} )

Here (x₁, y₁ ) = (- 4, - 9), (x₂, y₂ ) = (1, 1) and m : n = 3 : 2 , then

( \frac{2(-4)+3(1)}{3+2} , \frac{2(-9)+3(1)}{3+2} )

= ( \frac{x}{y} \frac{-8+3}{5}, \frac{-18+3}{5} )

=  ( \frac{-5}{5}, \frac{-15}{5} )

= ( - 1, - 3 )
