1 answer:
One hosta costs $7.
Step-by-step explanation:
Let,
Cost of one hosta = x
Cost of one ivy = y
According to given statement;
12x+5y=144 Eqn 1
6x+y=54 Eqn 2
In order to find cost of one hosta, we will eliminate y.
Multiplying Eqn 2 by 5;
Subtracting Eqn 1 from Eqn 3
Dividing both sides by 18
One hosta costs $7.

We have to draw a scaled copy of ABCD.
The position of the quadrilateral will not be referenced to any coordinate.
As we need to scale it with a factor of 3, then the side AD, for example, that has a length of 1, will have an image corresponding side A'D' with length 3*1=3.
This same calculation is applied to all sides.
We can use the grid to reference the direction of each of the sides.
For example, the side DC is one unit down and one unit right. Then, the corresponding side D'C' will move 3 units down and 3 units right.
With that information, we can draw tha quadrilateral as:
