Use the figure for 10 - 12. X is the midpoint of PQ.
10: Find PX
11. Find XQ
12. Find PQ
Answer:
see explanation
Step-by-step explanation:
since X is the midpoint of PQ , then
PX = QX ( substitute values )
4x + 15 = 7x + 6 ( subtract 4x from both sides )
15 = 3x + 6 ( subtract 6 from both sides )
9 = 3x ( divide both sides by 3 )
3 = x
Then
PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27
XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27
PQ = PX + XQ = 27 + 27 = 54
Answer:
PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27
XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27
PQ = PX + XQ = 27 + 27 = 54
Step-by-step explanation:
Since X is the midpoint of PQ , then
PX = QX ( substitute values )
4x + 15 = 7x + 6 ( subtract 4x from both sides )
15 = 3x + 6 ( subtract 6 from both sides )
9 = 3x ( divide both sides by 3 )
3 = x
Then
PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27
XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27
PQ = PX + XQ = 27 + 27 = 54
Hence, the correct answers are: PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27
XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27 PQ = PX + XQ = 27 + 27 = 54

1/4x=-5/8
a
Answer: x = 5/2 or 2.5
Step-by-step explanation:
1/4x = 5/8
To find the value of X;
We multiply both sides by 4
1/4 x × 4 = 5/8 × 4
x = 5/2 or 2.5
Hey there!
1/4x = -5/8
MULTIPLY 4/1 to BOTH SIDES
4/1 * 1/4x = -5/8 * 4/1
CANCEL out: 4/1 * 1/4 because it give you 1
KEEP: -5/8 * 4/1 because it give you the x-value
NEW EQUATION: x = -5/8 * 4/1
SIMPLIFY IT!
x = -5/2
Therefore, your answer is: x = -5/2
Good luck on your assignment & enjoy your day!

what is 6.729 x 8.3 (show ur work)
Answer:92,817,765
Step-by-step explanation:Arrange the numbers one on top of the other and line up the place values in columns. The number with the most digits is usually placed on top as the multiplicand.
Starting with the ones digit of the bottom number, the multiplier, multiply it by the last digit in the top number
Write the answer below the equals line
If that answer is greater than nine, write the ones place as the answer and carry the tens digit
Proceed right to left. Multiply the ones digit of the bottom number to the next digit to the left in the top number. If you carried a digit, add it to the result and write the answer below the equals line. If you need to carry again, do so.
When you've multiplied the ones digit by every digit in the top number, move to the tens digit in the bottom number.
Multiply as above, but this time write your answers in a new row, shifted one digit place to the left.
When you finish multiplying, draw another answer line below your last row of answer numbers.
Use long addition to add your number columns from right to left, carrying as you normally do for long addition.
Long Multiplication with Decimals
Long multiplication with decimals using the standard algorithm has a few simple additional rules to follow.
Count the total number of decimal places contained in both the multiplicand and the multiplier.
Ignore the decimals and right align the numbers one on top of the other as if they were integers
Multiply the numbers using long multiplication.
Insert a decimal point in the product so it has the same number of decimal places equal to the total from step 1.

what is $262.50 of $3000
Answer: 262.50 is 8.75% of 3000
Step-by-step explanation:
Solution for 262.50 is what percent of 3000:
262.50:3000*100 =
(262.50*100):3000 =
26250:3000 = 8.75
Now we have: 262.50 is what percent of 3000 = 8.75
Question: 262.50 is what percent of 3000?
Percentage solution with steps:
Step 1: We make the assumption that 3000 is 100% since it is our output value.
Step 2: We next represent the value we seek with x
Step 3: From step 1, it follows that 100% = 3000.
Step 4: In the same vein, x% = 262.50 .
Step 5: This gives us a pair of simple equations:
100% = 3000(1).
x% = 262.50(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x% = 262.50%/3000
x = 8.75% Therefore, 262.50 is 8.75% of 3000

What is the area of the semicircle window shown above?
Solution:
We know that the diameter of the semi-circle is 30 inches. Before we use the formula, let's find the radius of the semi-circle.
⇒ Diameter = 2(Radius)
⇒ 30 inches = 2(Radius)
⇒ Radius = 30/2 = 15 inches
The area of the circle is πr², but we need to find the area of the semi-circle. A semi-circle is basically half of a circle. This means that the area of a semi-circle is πr²/2. Now, let's solve for the area of the semi-circle.
⇒ πr²/2 = Area of semi-circle
⇒ (22/7)(15²)/2
⇒ (22/7)(225)/2
⇒ (22/7)(112.5)
⇒ 22/7 × 112.5
⇒ 2475/7 in²
Thus, the area of the semi-circle is 2475/7 in².

y = x² - 6x + 15. Write the equation in vertex form.
Write any numbers as integers or simplified proper or improper fractions.
Answer:
[tex]\displaystyle y = [x - 3]^2 + 6[/tex]
Step-by-step explanation:
Use the method called complete the square, but in this case, we need to take half of the B-term and square the result afterward. Here is how it is done:
[tex]\displaystyle [\frac{b}{2}]^2 \hookrightarrow [\frac{-6}{2}]^2; 9 \\ \\ \boxed{[x - 3]^2} \hookrightarrow x^2 - 6x + 9[/tex]
Now, after you get an equation from using this method, you must follow ONE MORE PROCEDURE, which is figuring the quantity out that when added to 9, you get 15, and that will be 6. So, with that, you have your vertex equation:
[tex]\displaystyle y = A[x - h]^2 + k \\ \\ \boxed{\boxed{y = [x - 3]^2 + 6}}[/tex]
**In the event you have a quadratic equation, if you are asked to locate the vertex, IF factourable, convert the quadratic equation to a vertex equation, where [tex]\displaystyle [h, k][/tex]represents the vertex:
[tex]\displaystyle y = Ax^2 + Bx + C \hookrightarrow y = A[x - h]^2 + k[/tex]

If you run 3 meters per second to the left, where will you be 4 seconds after you pass zero?
Answer:
12 meters to the left, or -12
Step-by-step explanation:
3 meters per second for 4 seconds
Meaning it's 3 x 4
3 x 4 = 12, so therefore it's -12 meters or just 12 meters to the left.
Answer:
12 meters to the left of your starting point.
Step-by-step explanation:
You start at 0 meters. You then start running to the left with an acceleration of 3 m/s to the left. After each seconds, you are 3 more meters to the left.
So
3 m/s * 4 s = 12 m to the left.
Hence, the answer in 12 meters to the left.

What is the radius of a circle whose equation is x2 y2 8x−6y 21=0?.
The radius of the circle of the provided equation, after comparing it with the standard equation of the circle, is 2.
What is the equation of circle?The equation of the circle is the equation which is used to represent the circle in the algebraic equation form with the value of center point in the coordinate plane and measure of radius.
The standard form of the equation of the circle can be given as,
[tex](x-h)^2+(y-k)^2=r^2[/tex]
