Answer:
12
Step-by-step explanation:
-25 from both side
x^2= 144
then you square root it
x= 12
[tex]\huge\text{Hey there!}[/tex]
[tex]\mathsf{x^2 + 25 = 169}[/tex]
[tex]\text{Subtract 25 to both sides}\downarrow[/tex]
[tex]\mathsf{x^2 + 25 - 25 = 169 - 25}[/tex]
[tex]\text{Simplify it}\downarrow[/tex]
[tex]\mathsf{x^2 = 169 - 25}[/tex]
[tex]\mathsf{x^2 = 144}[/tex]
[tex]\text{Take the square root of the numbers (including the mystery number (x))}\downarrow[/tex]
[tex]\mathsf{x = \pm \sqrt{144}}[/tex]
[tex]\text{So, that means that}\downarrow[/tex]
[tex]\mathsf{x = 12}[/tex]
[tex]\text{Or even:}[/tex] [tex]\mathsf{x = -12}[/tex]
[tex]\huge\text{Therefore, your answer should be:}[/tex]

3) You are selling raffle tickets. You sell tickets to adults and children. You sell a
total of 475 tickets. Adult tickets cost $3 per ticket and children tickets cost $2
per ticket. You earn a total of $1200. How many adult tickets and how many
children tickets were sold?
Answer:
Step-by-step explanatiox
x+y = 475
3x + 2y = 1200
3(-y + 475) = 1200
-3y + 1425 = 1200
-3y = -225
y= 75 kids
x = 350

Which one is the correct answer? 33 or 44 or 32 or 66. Pls explain and thanks in advance!
=================================================
Explanation:
Points R, O, and A are midpoints of sides XY, YG, and XG respectively.
Because of this, we know that the points cut those sides into two equal halves.
To elaborate, we know the following three facts:
Point R is the midpoint of XY, so XR = RYPoint O is the midpoint of YG, so YO = OGPoint A is the midpoint of XG, so XA = AGThe diagram shows that YO = 14, so OG must be 14 units long as well.
The diagram also shows XA = 8. Since XA = AG, we know that AG = 8.
-----------------------------
Use this information to find the perimeter of triangle XYG.
Perimeter of XYG = sum of all the sides
Perimeter of XYG = (XY) + (YG) + (XG)
Perimeter of XYG = (22) + (YO+OG) + (XA+AG)
Perimeter of XYG = 22 + (14+14) + (8+8)
Perimeter of XYG = 66
-----------------------------
Then we cut this in half to get the perimeter of triangle ROA.
We do this because each segment of ROA is half that of the corresponding segment of XYG. The midsegments (RA, RO, AO) are cut in half and are parallel to the opposite side.
So,
Perimeter of ROA = (1/2)*(Perimeter of XYG)
Perimeter of ROA = (1/2)*(66)
Perimeter of ROA = 33

13-2(4r-5) =-(7+8r) please show work
Answer:
r = no solutions
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
13 - 2(4r - 5) = -(7 + 8r)
Step 2: Solve for r
Distribute: 13 - 8r + 10 = -7 - 8rCombine like terms: -8r + 13 = -7 - 8rAdd 8r on both sides: 13 ≠ -7Here, we see that 13 does not equal -7. ∴ r has no solutions.
The following table shows the number of heartbeats for four animals for example if it's heartbeat 225 in 3 minutes what animals heart beats ate a rate of 65 beats per minute?
Answer:cow
Step-by-step explanation:
y=5x-4y = 5 x − 4
y=-x+2
Answer:
Y= x+2 " substituting value of y
Step-by-step explanation:
Y=5x-4y = 5x - 4
or, 5x - 4(x+2) = 5x - 4
or, 5x - 4x+ 8 = 5x-4
or, x +8 = 5x - 4
or, 0= 5x - x - 4-8
or, 0= 4x - 12
the radius of a circle is 18 in what is the area and circumference
Answer:
324 pi . and 36 pi
Step-by-step explanation:
Area is pi r squared, so 18x18 is 324, times pi which is 324 pi
Circumference is 2 pi r, which is 2 times 18 which is 36, times pi which is 36 pi

Determine whether the following graph represents a function
Answer:
It is not a function
Step-by-step explanation:
Question 4(Multiple Choice Worth 6 points)
(03.04 LC)
Write the equation of the graph shown below in factored form.
the graph starts at the bottom left and continues up through the x axis at negative two to a maximum around y equals eight and goes back down through the x axis at one to a minimum around y equals negative four and back up through the x axis at three
f(x) = (x + 2)(x − 1)(x − 3)
f(x) = (x − 2)(x + 1)(x + 3)
f(x) = (x + 2)(x + 1)(x + 3)
f(x) = (x − 2)(x − 1)(x − 3)

y = (x +2)(x -1)(x -3)

The equation of a line is y = -3x - 2. What are the slope and the y-intercept of the line? slope = -3 and y-intercept = 2 slope = 3 and y-intercept = -2 slope = 3 and y-intercept = 2 slope = -3 and y-intercept = -2
Answer:
slope -3 and y-intercept -2
Step-by-step explanation:
The slope:
the general linear function is y=mx+n where m is the slope
so slope = -3
y intercept is when x=0
y=-3*0-2
y=-2
