B. The variable d represents an unknown number. So, 21+d, is equal to 21+an unknown number.
Answer:
125, 105, 120
Step-by-step explanation:
You would first make an equation with what you know:
x + 45 + x + 25 + x + 40 = 350.
Now, you would simplify and add like terms.
3x + 110 = 350
Now, you would subtract 110 from both sides.
3x = 240
Now, you would divide both sides by 3.
x = 80
Now that you know what x is, simply plug it in to the respective equations for all three sides.
x + 45 would become 80 + 45, and add up to 125.
x + 25 would become 80 + 25, and add up to 105.
x + 40 would become 80 + 40, and add up to 120.
To check your work, you would now add the three totals.
125 + 105 + 120 = 350.
<em>Hello!</em>
<u><em>Here are your answers:</em></u>
<em>-It is greater than 3</em>
<em>-It is between 3 and 4</em>
<em>This is based off of the options that were given.</em>
The relationship is linear because x is increasing at a constant rate of 6, and y is decreasing at a constant rate of 3.
The equation of the line is y+4=-1/2(x-1).
The answer is A
