The system of equations are:
$12p + $3a = $258
a - p = 6
Where:
- a = phone accessories
- p = phone
<h3>What are the system of equations?</h3>
Two linear equations would be derived from the question. The linear equations would be a function of the phones and accessories sold. These equations are known as simultaneous equations and they would have to be solved together in order to determine the required values.

Answer:
The first piece is 5 inches long, while the second is 15 inches and the third one is 20 inches.
Step-by-step explanation:
To determine the length of the 3 pieces, knowing that the total of the board is 40 inches, and that the second measures 3 times more than the first and the third measures 4 times more than the first, the following equation must be performed:
X + 3X + 4X = 40
8X = 40
X = 40/8
X = 5
Therefore, the first piece is 5 inches long, while the second is 15 inches and the third 20 inches.
Answer:
Cost of Hats = $15
Cost of Scarves = $8
Step-by-step explanation:
Let
Cost of Hats = x
Cost of Scarves = y
5x + 3y = 99 (1)
3x + 5y = 85 (2)
Multiply (1) by 5 and (2) by 3
25x + 15y = 495
9x + 15y = 255
Subtract
25x - 9x = 495 - 255
16x = 240
Divide both sides by 16
x = 240 / 16
= 15
x = $15
Substitute x = 15 into
5x + 3y = 99
5(15) + 3y = 99
75 + 3y = 99
3y = 99 - 75
3y = 24
y = 24/3
= 8
y = 8
Cost of Hats = $15
Cost of Scarves = $8
Hey there! How is your day going?
Sorry if I'm a bit rusty here, math isn't my best subject, necessarily.
If you will notice ABCD is similar in size to EFGH, but the measurements are multiplied by 5. So, all we need to do is multiply the area of ABCD by 5.
35 x 5 = 175
So, your answer is 175 ft²
I hope this helped you, as it has helped me learn a different way to find the area of a rectangle. And I hope you have a very nice day!
Your friend in answering and in need,

The last one because for every functoin pair their is exactly one output value fo the function pair.
