find the value of the variable (3p-6)
Answer:1/3
Step-by-step explanation:
3p- -5=6
- and - becomes +
3p+5=6
transpose 5 to the other side
3p=6-5
because on transposing + becomes -
3p=1
p=1/3
because multiplication changes to addition on transposing

Tavon has a gist card for $145 that losses $3.50 for each 30-day period is not used. He has another gift card for $125 that losses $3 for each 30-day period it is not used. A. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. B. What will the value of each card be when they have equal value?
Step-by-step explanation:
A. For Tavon's gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=145-3.5x------1
for Tavon's second gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=125-3x-------------2
B. equating 1 and 2 we have
145-3.5x=125-3x
solve for x we have
145-125=-3x+3.5x
20=0.5x
divide both sides by x we have
x=20/0.5
x= 40
put x=40 in
y=145-3.5*40------1
y=145-140
y=$5
put x=40 in
y=125-3*40------1
y=125-120
y=$5

The answer is 74.
I need to show my work.
THANK YOU!!!!!
Answer:
x = 74
Step-by-step explanation:
If you add all the angles in the diagram, you will get 360 degrees (since it's a complete revolution, and one revolution = 360 degrees).
Form an equation in x with this information:
4x+1+x-35+24 = 360
5x -10 = 360
5x = 370
x = 74
What is the value of x? What is the measure of angle 6? Show all of your work and/or explain your answer.
Answer:
1) 5 & 9
5=Corresponding Angle
9=Alternate Exterior Angle
2) 7 & 8
We know 4 is supplementary to 8. Since that is true, 7 & 8 are also.
8=Corresponing angle to 4
7=Verticle angle to 8
3) We know 1 and 3 equal 180
x-20+x+40=180
2x+20=180
2x=180-20
2x=160
x=80
<2=X+20
=80+20
=100
Angle 2 is the same as angles 5 and 6 added together.
We know angle 5 is the same as angle 1 (corresponding angles).
<1=X-20
=80-20
=60
Now that we know <2=100 and <5=60, we can figure out <6
100-60=40
<6=40°
Step-by-step explanation:

Step-by-step explanation:
Maya claims that 8n is the number of dots in figure n. Kiana claims that the number of dots in figure n is given by 4(n+1)
Consider the square arrangements below in relation to the girls' expressions, where n represents the figure number.
Determine whether Maya, Kiana or both girls are correct in their given expressions. Justify your response.
The evaluation of your response will be based on the following criteria.
Answer:
Answer:
Kaya's answer is correct.
Step-by-step explanation:
The number of dots in successive figures are
8, 16, 24.
So Kaya's solution 8n is correct.
When n = 1, first square = 8*1 = 8 dots
n = 2: second square = 8*2 = 16
n = 3, 3rd square = 8*3 = 24.
If I have interpreted Kianna's formula correctly
for n = 1, then the number of dots = 2(1+ 1)^2 - 2(1 - - 1)^2
= 0.
Marcus reads in a magazine article that 62% of teenagers prefer Batman over Iron Man. He decides to test this so he takes a simple random sample of 50 people at Wal-Mart on a Sunday afternoon. What is the probability that he finds exactly 40 Batman fans? Round to the nearest thousandth.
Answer:
The probability is 0.003
Step-by-step explanation:
If 62% prefers Batman, the percentage that prefers Iron man will be (100-62)% = 38%
So the probability of finding a teenager that likes batman will be 62/100 = 0.62
The probability of finding a teenager that prefers iron man will be 38/100 = 0.38
Now, we want to find the probability that out of 50 people at Walmart on a Sunday, exactly 40 prefers Batman
We can use the Bernoulli approximation of the binomial theorem ;
let probability of liking Batman be q and that of iron man be q
Thus the approximation will be;
P(X = 40) = 50 C 40 (0.62)^40 (0.38)^10
= 0.003200147531
To the nearest thousandth, this is 0.003

suppose you are buying two kinds of chips for a party. Each bag of potato chips cost $2.50 and each bag of corn chips cost $2.90. You must have at least 100 bags of chips for the party and the total cost of the chips can be no more than $350
Part A:Write a system of two inequalities that describe the situation
Part B: Write one possible solution to the problem in sentence form
Answer:
At least means ≥
No more than means ≤
Let x = number of bags of potato chips
Let y = the number of bags of corn chips
x+y≥100
2.50x+2.90y≤$350
Let's try x=80 and y=20 (We know that is equals 100 so it will work for the first equation
2.50(80)+2.90(20) = 258 which is ≤$350
Buy 80 bags of potato chips and 20 bags of corn chips is one possibility.
The amount of money left in Alma's bank account is expressed by the linear equation y = -27x + 577, where x represents the number of weeks and y represents the amount of money left in her account. After how many weeks will Alma have $145 left in her account? 12 weeks 16 weeks 22 weeks 26 weeks
Given:
The linear equation is
[tex]y=-27x+577[/tex]
where x represents the number of weeks and y represents the amount of money left in Alma's account.
To find:
The number of weeks in which Alma have $145 left in her account.
Solution:
We have,
[tex]y=-27x+577[/tex]
Substitute y=145, we get
[tex]145=-27x+577[/tex]
Subtract both sides by 577.
[tex]145-577=-27x[/tex]
[tex]-432=-27x[/tex]
Divide both sides by -27.
[tex]\dfrac{-432}{-27}=\dfrac{-27x}{-27}[/tex]
[tex]16=x[/tex]
So, the number of required weeks is 16. Therefore, the correct option is B.

Step-by-step explanation:
Tom es el gerente del departamento de delicatessen en una tienda de comestibles. Debe programar que los empleados trabajen en el departamento durante al menos 260 horas a la semana. Tom tiene un empleado a tiempo parcial que trabaja 20 horas a la semana. Cada empleado a tiempo completo trabaja 40 horas a la semana. Escriba una desigualdad para determinar nnn, el número de empleados a tiempo completo que Tom debe programar para que sus empleados trabajen al menos 260 horas a la semana.
Answer:
La desigualdad para determinar el número de empleados a tiempo completo que Tom debe programar para que sus empleados trabajen al menos 260 horas a la semana es 20+40*n ≥ 260. Resolviendo al menos 6 empleados deben trabajar a tiempo completo.
Step-by-step explanation:
Una inecuación es una desigualdad entre letras (incógnitas) y números relacionados por operaciones aritméticas. Su conjunto solución es el conjunto de números reales que la satisfacen. En una desigualdad, dos expresiones algebraicas están conectadas a través de los signos: mayor que >, menor que <, menor o igual que ≤ y mayor o igual que ≥.
Tom tiene un empleado a tiempo parcial que trabaja 20 horas a la semana. Cada empleado a tiempo completo trabaja 40 horas a la semana. Tom debe programar para que sus empleados trabajen al menos 260 horas a la semana.
Sabiendo que x representa la cantidad de trabajadores a medio tiempo y n la cantidad de trabajadores a tiempo completo, entonces 20*x+40*n representa la cantidad de horas que todos los empleados trabajan semanalmente. Si los empleados trabajen al menos 260 horas a la semana, esto significa que la cantidad de horas que todos los empleados trabajan a la semana debe ser mayor o igual a 260 horas. Entonces:
20*x+40*n ≥ 260
Si Tom tiene un empleado a tiempo parcial, entonces la cantidad de trabajadores a medio tiempo x debe tener un valor de 1. Entonces:
20*1+40*n ≥ 260
20+40*n ≥ 260
40*n ≥ 260 -20
40*n ≥ 240
n ≥ 240 ÷40
n ≥ 6
Entonces 6 empleados o más deben trabajar a tiempo completo.

What is Venn diagram?
"A Venn diagram in mathematics is a diagram that uses overlapping circles or other shapes to represent the logical relationships between two or more sets of items. "
What is probability?"For any experiment, a probability denotes the possibility of outcome for any event."
The formula to calculate the probability of an event:For event A, the probability of event A is,
P(A) = number of favorable outcomes/ total umber of outcomes
What is conditional probability?"Conditional probability is the probability of an event occurring given that another event has already occurred."
The formula to calculate the conditional probability:P(A|B) = P(A∩B)÷P(B)
For given diagram:
Let A represents a set of students playing Basketball and B represents a set of students playing Soccer
So, A = {Fran, Ian, Juan, Ella}
⇒ n(A) = 4
B = {Mickey, Marcus, Ella}
⇒ n(B) = 3
(A ∩ B) = {Ella}
⇒ n(A ∩ B) = 1
sample space: S = {Fran, Ian, Juan, Ella, Mickey, Marcus, Mai, Karl, Jada, Gabby}
⇒ n(S) = 10
Now, we calculate probability of B and A∩B.
P(B) = n(B)/n(S)
⇒ P(B) = 3/10
Also, P(A∩B) = n(A∩B) / n(S)
⇒ P(A∩B) = 1/10
So, the required probability would be,
⇒ P(A|B) = P(A∩B) ÷ P(B)
⇒ P(A|B) = (1/10) ÷ (3/10)
⇒ P(A|B) = 1/3
Therefore, P(A|B) = 1/3
