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
Answer:
Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.
Step-by-step explanation:
Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.
