Answer:
Hence the pricing for each product will be taronges with 2 euros and mandarins with 2.5 euros.
Step-by-step explanation:
Given:
2 kg of taronges and 3 kg mandarins cost 11.5 euros
3kg taronges and 2 kg mandarins cost 11 euros
To Find:
Price for each product
Solution:
<em>Consider </em>
<em>Taronges =x euros</em>
<em>Mandarins=y euros</em>
So by given condition,
....................equation(1)
and ...........equation (2)
So , using substitution method,
.......equation (3)
Using above value in equation(1) we get ,
)
y=2.5 euros
Using above value in equation(3) we get ,
x=2 euros
Answer:
Side length and perimeter of 1 face
Area of 1 face and surface area
Step-by-step explanation:
Suppose you are given cube with side length of x units.
Then
Side length = x units
Perimeter = 4x units
Area of 1 face square units
Surface area square units
Volume cubic units
A linear relationship is any equation that, when graphed, gives you a straight line.
Consider all options:
A. Side length and perimeter of 1 face is a linear relationship, because the graph of the function is a straight line.
B. Perimeter of 1 face and area of 1 face is not a linear relationship, because the graph of this relationship is a quadratic parabola with equation .
C. Surface area and volume is not a linear relationship, because the graph of this relationship is a curve with equation .
D. Area of 1 face and surface area is a linear relationship, because the graph of the function is a straight line.
E. Side length and volume is not a linear relationship, because the graph of this relationship is a cubic parabola with equation .
