Shirts-2-Go sells t-shirts for a base price of $12 per shirt plus a fixed fee of $3 shipping and handling for the whole order. S

Andrew [12]

Answer:

$5\ shirts$

Step-by-step explanation:

Let

x------> the number of shirts ordered

y-----> the total cost of the order

we know that

The linear equations that represent each situation are

<u>Shirts-2-Go</u>

$y=12x+3$ ------> equation A

<u> Shirts PLUS</u>

$y=8x+23$ ------> equation B

To know how many shirts to purchase so that the total cost is the same in both companies, equate equation A and equation B

$12x+3=8x+23$

$12x-8x=23-3$

$4x=20$

$x=5\ shirts$

Given circle N with chord AB, which point lies on the perpendicular bisector of AB?

aivan3 [116]

The point that lies on the perpendicular bisector of AB is point N

<h3>How to determine the point?</h3>

The circle is given as:

Circle N

The chord is given as:

Chord AB

The perpendicular bisector of the chord is any line drawn from the center of the circle that divides the chord in equal halves.

This means that the point starts from point N

Hence, the point that lies on the perpendicular bisector of AB is point N
