A system of equations that could be used to determine the number of cans of soup purchased and the number of frozen dinners purchased is:
350x + 500y = 4800
y = 2x
<h3>Definition of variables </h3>
x = number of cans of soup purchased
y = number of frozen dinners purchased.
<h3>Simultaneous equations </h3>
The system of equations are known as simultaneous equations. Simultaneous equations are group of equations that have to be solved together in order to determine the required values.
<h3>Methods used to solve simultaneous equations </h3>
- Elimination method
- Graph method
- Substitution method

Answer:
The maximum number of hours the school can have the band play at the dance is 4.
Step-by-step explanation:
150 + 100 + 35x ≤ 390
250 + 35x ≤ 390
subtract 250 from both sides
35x ≤ 140
divide by 35 on both sides
x ≤ 4
Area of circle 1 = πr²
Area of circle 1 = π (10)²
Area of circle 1 = 100π km²
Area of circle 2 = πr²
Area of circle 2 = π (5)²
Area of circle 2 = 25π km²
