Answer:
$54
Step-by-step explanation:
First, we calculate the amount she paid for each pen.
$255/5 = $51
She paid $51 for each pen.
She made a profit of $3 per pen, so she sold each pen for $51 + $3 = $54
Answer: $54
If your asking to select all that apply,
The formula is arc length = θ ( r ) {\displaystyle {\text{arc length}}=\theta (r)} , where equals the measurement of the arc's central angle in radians, and r {\displaystyle r} equals the length of the circle's radius. Plug the length of the circle's radius into the formula.

In the given question, we have to perform this experiment and test if the inequality is true or not.
Adding the same value to both sides of the inequality will not change the inequality sign

data;
- 4 < 7
- 11 > - 2
- -4 < - 2
- -8 < 8
In the first case, we would do follow the process

In the second case;

In all the scenarios, the operations did not affect the inequality sign because we are doing it equally to all side and at the end of the day nullifies each other.

Answer:
x +4y = -5
Step-by-step explanation:
The equation of the perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The new constant can be found by substituting the point values into the equation.
3x +12y = 3(-5) +12(0)
3x +12y = -15
We notice that all of the values include a factor of 3. We can divide that out to put the equation in standard form:
x + 4y = -5
