Answer:
there were a total of 55 people at the party.
Step-by-step explanation:
In order to create the equation representing this scenario we first need to represent each step in a formula. Since the total number of people is represented by x we can multiply 3/5 by x and subtract 9 from that. This would then be equal to 24 like so...
3/5x - 9 = 24
Now that we have the formula we can perform opposite operations to isolate x and solve for it.
3/5x - 9 = 24 ... add 9 on both sides
3/5x = 33 ... divide both sides by 3/5
x = 55
Finally, we can see that there were a total of 55 people at the party.
what is 1/5 + 1/6=
Pls I need help
Answer:
So the first step would be is to multiply the denominators so you would get this:
6/30 + 5/30
Then you would have 11/30 no simplification needed.
Se image below for more info:
Answer:
11/30
Step-by-step explanation:
To add fractions, you need to find the common denominators
the common denominator for 5 and 6 is 30, because 5*6 = 30
1/5 times (6/6) to get a common denominator of 30. Remember, you have to multiply the numerator by 6 too!
1 6 6
_ x _ = _
5 6 30
Now, we just have to multiply 1/6 by (5/5) to get a common denominator of thirty.
1 5 5
_ x _ = _
6 5 30
5 6 11
_ + _ = _
30 30 30
You final answer should be 11/30
What is equation of the line graphed below?
[tex](0,0) \longrightarrow \sf{part \: \: of \: \: the \: \: graph} \\ (1, - 3)\longrightarrow \sf{given \: \:coordinate \: \: point}[/tex]
[tex]m = \frac{dy}{dx} = \frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute these coordinate values in.
[tex]m = \frac{0 - ( - 3)}{0 - 1} \\ m = \frac{3}{ - 1} \\ m = - 3[/tex]
Hence, the slope is -3.
Find the y-intercept.From the graph, the line passes through the origin point. Therefore, the y-intercept is (0,0).
Slope-Intercept form[tex]y = mx + b \\ \begin{cases} \sf{m = slope} \\ \sf{b = y - intercept} \end{cases}[/tex]
Substitute both m and b in the slope-intercept form.
[tex]y = - 3x + 0 \\ y = - 3x[/tex]
Hence the answer is y = -3x.
Answer[tex] \large \boxed{y = - 3x}[/tex]
90° clockwise rotation
Help please
Answer:
E' (-2,5)
F' (-3,1)
G' (-2,-1)
H' (0,3)
Step-by-step explanation:
The rule for 90 degree clockwise rotation is (h,k) -> (k,-h). This means flip the x-value's sign and then switch x and y's position. For example E (-5,-2), first flip x's sign (5,-2) and then switch x and y's places (-2,5).

2x - 3y = 1
3x + y=-5
Solve geographically
Answer:
1) x=3/2y+1/2
2)x=-1/3y+-5/3
Step-by-step explanation:
1)
Let's solve for x.
2x−3y=1
Step 1: Add 3y to both sides.
102x−3y+3y=1+3y
2x=3y+1
Step 2: Divide both sides by 2.
2x/2
=
3y+1/2
x=3/2y+1/2

The perimeter of a rectangular coffee table is given by the trinomial 2t2+4t+2. The table's length is 2t-3. What is the table's width?
Answer:
t^2+4
Step-by-step explanation:
The perimeter of the table can be given by the equation 2l+2w, and we know the length is 2t-3, meaning 2(2t-3)+2w=2t^2+4t+2, as we know 2t^2+4t+2 is the perimeter. Simplifying we get:
4t-6+2w=2t^2+4t+2
4t+2w=2t^2+4t+8
2w=2t^2+8
w=t^2+4
This means that the table's width is t^2+4
Two circles with radii 3.5 cm and 2.5 cm touch each other internally. Find the distance between their centres.
Answer:
1cm
Step-by-step explanation:
Kindly refer to the attached image for clarity
Given data
Let the big circle have a radius R= 3.5cm
and the small circle have a radius r= 2.5cm
From the image, we can see that the distance between the two centers is the difference of the radii
Distance= R-r
Distance= 3.5-2.5= 1cm
Hence the distance is 1cm

A modified roulette wheel has 32 slots. one slot is 0, another is 00, and the others are numbered 1 through 30, respectively. You are placing a bet that the outcome is an odd number. (In roulette, 0 and 00 are neither odd nor even.)<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

The probability of winnign is ?
( type an integer or a simplified fraction)
b. What are the actual odds against winning are ?
c. When you bet that the outcome is an odd number, the payoff odds are 1:1. How much profit do you make if you bet $17 and win ?
If you win, the pay off is ?
d. How much profit should you make on the $17 bet if you could somehow convice the casino to change its payoff odds so that they are the same as the actual odds against winning ?
(rounds to the nearest cent as needed.)Type your question here
Answer:
0.46875 ; 1.133 ; $17 ;19.27
Step-by-step explanation:
Number of slots = 32
0, 00, {1,.. 30}
Odd outcomes = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29}
1.) probability of winning :
P(winning) = number of odd outcomes / tot possible outcomes
P(winning) = 15 / 32 = 0.46875
2.)
Odds against winning :
Number of losing outcomes / number of winning outcomes
Not odd numbers / odd numbers = 17 /15 = 1.133
C.)
Payoff odd = 1:1
If bet value = $17 ;
Profit made on winning = $17 * 1 = $17
d.)
If Payoff odd = odd against winning = 17 / 15
Profit on $17
17/ 15 * 17
(1.1333333) * 17
= 19.27

find the value of each angle.
Answer + Explanation:
First, find what the sum of the interior angles must be. You can use the formula 180(n - 2) where n is the number of sides to find this.
n = 5, so 180( 5 - 2) = 180 * 3 = 540 degrees.
Then, you can add up all the interior angles of the pentagon and it will add to 540. This means that:
2x + x + 2x + 90 + 90 = 540
5x + 180 = 540
5x = 360
x = 72
Then you can go through and find the measure of each angle:
S = 90 degrees (given)
T = 2x = 2 * 72 = 144 degrees
U = x = 72 degrees
V = 2x = 72 * 2 = 144 degrees
W = 90 degrees (given)
what is the nth term of 5,11,17,23
Answer:
6n - 1.
Step-by-step explanation:
Arithmetic sequence.
a1 = 5, d = 6.
nth term = a1 + d(n - 1)
= 5 + 6(n - 1)
= 5 + 6n - 6
= 6n - 1.

Dos aviones salen del mismo aeropuerto,uno se dirige hacia el norte y el otro,al oriente.Cuando estan a 1580 km de distancia uno del otro,uno de ellos ha recorrido 800 km¿Que distancia ha recorrido el otro avion?
Answer: El otro avión recorrió a distancia de 1362.5 km.
Step-by-step explanation:
Vamos a definir:
Norte es el eje y-positivo.
Oriente (o este) es el eje x-positivo.
Y también sabemos que si tenemos los puntos (a, b) y (c, d)
La distancia entre esos puntos es:
Distancia = √( (a - c)^2 + (b - d)^2)
Ahora, uno de los aviones va hacia el norte, entonces si el aeropuerto está en la posición (0, 0), después de un rato viajando hacia el norte su nueva posición va a ser (0, A)
Mientras que el que va al oeste va a tener una nueva posición (B, 0)
La distancia entre ellos es:
Distancia = √( (B - 0)^2 + (0 - A)^2) = √( B^2 + A^2)
Sabemos que cuando la distancia entre ellos es 1580 km, uno de ellos ha recorrido 800km, asumamos que A = 800km.
Entonces tenemos la ecuación:
1580 km = √( B^2 + (800km)^2)
(1580km)^2 = B^2 + (800km)^2
(1580km)^2 - (800km)^2 = B^2
√((1580km)^2 - (800km)^2 ) = B = 1362.5 km
El otro avión recorrió a distancia de 1362.5 km.

What number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation?
What number would you multiply the second equation by in order to eliminate the y-terms when adding to the first equation?
Answer:
To eliminate the x-terms, multiply the second equation by 2.
To eliminate the y-terms, multiply the second equation by 3.
Step-by-step explanation:
The first step of solving by elimination requires that you eliminate either the x-terms or y-terms by making the two terms have the same coefficient, but opposite signs.
So, if you wanted to eliminate the x-terms, you could multiply the second equation so that its x term has the same coefficient as the x-term in the first equation, but with opposite signs. The x-term in the first equation is 4x. The x-term in the second equation is -2x. They already have opposite signs, so we just need the -2x to become -4x. -4x divided by -2x is 2, thus you would multiply the second equation by 2.
If you wanted to eliminate the y-terms, the process is the same. The y-term in the first equation is -9y and the y-term in the second equation is 3y. Again, they already have opposite signs, we just need 3y to become 9y. 9y divided by 3y is 3, thus you would multiply the second equation by 3.

Answer:
w = 215 degrees
Step-by-step explanation:
A circle = 360 degrees total. So, 145 + w should equal 360.
145 + w = 360
145 + w -145 = 360 - 145
w = 215
