Answer:
15p
Step-by-step explanation:
<u>Let's interpret the question bit by bit</u>
<em>Salvador wrote 15 letters to friends each month</em>
=> 15 letters = 1 month
<em />
<em>For p months in a row</em>
let the total number of letters for p months be x
=> x letters = p months
<em>Bringing the two statements together gives;</em>
15 letters = 1 month
x letters = p months
<em>Now, let's solve for </em><em>x </em><em>by cross-multiplying the above</em>
x letters * 1 month = 15 letters * p months
x = 
x = 15p letters
Therefore, Salvador wrote a total of 15p letters for the p months.
Answer:
C. Create the perpendicular bisector of FG. Then use the points of intersection of the perpendicular bisector with the circle, along with points F and G, to draw the square.
Step-by-step explanation:
The steps are below:
1. A diameter of the circle is drawn.
2. A perpendicular bisector of the diameter is drawn using the method described in the perpendicular bisector of a segment. This is also a diameter of the circle.
3. The resulting four points on the circle are the vertices of the inscribed square.
Answer:
$64.32
Step-by-step explanation:
What you do is:
$53.60×20% → $53.60×0.2
$53.60×0.2=$10.72
$10.72 is the amount of money taken off because of the sale.
Then what you do is:
$53.60+$10.72=_____
53.60
<u>+10.72</u>
64.32
The original price was $64.32.

Answers and Step-by-step explanations:
9-18.
a) All the angles of a triangle add up to 180, by definition. So, we can write the expression: 30 + 115 + x = 180.
Then, we can just solve for x by subtracting 30 and 115 from both sides:
x = 180 - 115 - 30 = 35 degrees
b) Again all three angles should add up to 180, so:
x + x + x = 180 ⇒ 3x = 180 ⇒ x = 180/3 = 60 degrees
9-19.
a) These angles add up to 180:
2x + x + 30 = 180 ⇒ 3x + 30 = 180 ⇒ 3x = 150 ⇒ x = 50
2x = 50 * 2 = 100
The missing angles are 100 degrees and 50 degrees.
b) Again, these add up to 180:
x + 10 + x + 90 = 180 ⇒ 2x + 100 = 180 ⇒ 2x = 80 ⇒ x = 40
x + 10 = 40 + 10 = 50
The missing angles are 50 degrees and 40 degrees.
Hope this helps!
