Aria has a points card for a movie theater. She receives 85 rewards points just for signing up. She earns 12.5 points for each visit to the movie theater. She needs 185 points for a free movie ticket. How many visits must Aria make to earn a free movie ticket?
Answer:
8 visits
Step-by-step explanation:
Create an equation, where x is the number of visits to the theater.
Since she gets 12.5 points for each visit, the number of points from visits will be represented by 12.5x.
85 will be added to this, since she gets 85 points for signing up. Then, this will be set equal to 185, since she needs 185 points for the free ticket.
12.5x + 85 = 185
Solve for x:
12.5x = 100
x = 8
So, Aria needs to make 8 visits to earn a free movie ticket
Aria must make 8 visits to earn a free movie ticket when She needs 185 points for a free movie ticket.
By given she has 85 rewards points just for signing up.
She earns 12.5 points for each visit to the movie theater.
She needs 185 points for a free movie ticket.
We must find how many visits does aria has to make to earn a free movie ticket
What is equation?If two expressions with equal sign is called as equation.
Let x is the number of visits to the theater.
Since she gets 12.5 points for each visit, the number of points from visits will be represented by 12.5x.
85 will be added to this, since she gets 85 points for signing up. Then, this will be set equal to 185, since she needs 185 points for the free ticket.
12.5x + 85 = 185
12.5x = 100
x = 8
So, Aria needs to make 8 visits to earn a free movie ticket

Which equation represents a proportional relationship?
Answer:
B, for every y there are 150 x's
When xb= 12, y = 8. Find x when y = 12
Answer:
If it is direct proportionality, then y = kx where k is a constant. Use the given information to find k:
8 = k(12) ⇒ k = 8/12 = 2/3
y = (2/3) x
For y = 12,
12 = (2/3) x ⇒ x = (3/2)*12 = 18
x = 18 when y = 12

as a town gets smaller the population of its high school decreases by 5% each year. The senior class has 160 students now. In how many years will it have about 100 students? Write an equation. Then solve the equation without graphing. Write an equation to represent the situation. Let n be the number of years before the class will have 100 students.
Answer:
T_n = 160(0.05)^(n - 1)
At T_n = 100, n = 1 year
Step-by-step explanation:
We will use geometric progression to solve this question.
Formula for nth term of a GP is;
T_n = ar^(n - 1)
We are told the population of its high school decreases by 5% each year.
This means r = 0.05
senior class has 160 students. Thus a = 160
Thus,T_n = 160(0.05)^(n - 1)
Where n is number of years after now.
We want to find the number of years before the class will have 100 students
Thus;
160(0.05)^(n - 1) = 100
(0.05)^(n - 1) = 100/160
(n-1)In 0.05 = In (100/160)
-2.9957(n - 1) = -0.47
(n - 1) = 0.47/2.9957
n = 1 + 0.1569
n = 1.1569
Approximating to the nearest whole number gives n = 1

Step-by-step explanation:
what two numbers multiply to 56 and add to -15
Answer:
-7 and -8
Step-by-step explanation:
because 7 times 8 equals 56 and negative times a negitive equals a positive and -7 added to -8 equals -15
The pair of numbers which fulfill the given condition 2.6 & -1.76
and -17.6 & 2.6.
What is a quadratic equation ?An equation is quadratic in form if it can be written in the form of ax + bx + c = 0, where a, b, and c are constants and x is the variable.
Let x and y be the two numbers we're trying to find. We know that:
x * y = 56 (equation 1)
x + y = -15 (equation 2)
y = -15 - x (equation 3)
Substituting equation 3 into equation 1, we get:
x * (-15 - x) = 56
-x² - 15x + 56 = 0
x² + 15x - 56 = 0
Using the quadratic formula, we get:
x = (-b ± √(b² - 4ac)) / 2a
where a = 1, b = 15, and c = -56.
Substituting the values, we get:
x = (-15 ± 20.2) / 2
x = (-15 + 20.2) / 2 = 2.6
x = (-15 - 20.2) / 2 = -17.1
For x = 2.6:
y = -15 - x = -15 - 2.6 = -17.6
So, one possible pair of numbers is x = 2.6 and y = -17.6.
For x = -17.1:
y = -15 - x = -15 - (-17.1) = 2.1
So, another possible pair of numbers is x = -17.1 and y = 2.1.
Therefore, the two numbers that multiply to 56 and add to -15 are approximately -17.1 and 2.6, or vice versa.

Here, we want to write the inequality represented
We start by looking at the value on which we have the circle
It is on the value 3
we can also see that the circle is unshaded and also that, the graph faces the right direction
As the circle
is unshaded, we have it that we only use the inequality without the equal to

Find all real zeros of the polynomial p(x)=2x^3+3x^2-8x-12
Answer is C B usatestprep
I need help ASAP!!!!!!
Answer:
1. YES 2. NO
Step-by-step explanation:
1. Since x=0.121212... and the question is asking for 100x, we need to multiply each side by 100. 0.121212... multiplied by 100 is 12.1212... So YES, 100x is still a repeating decimal.
2. 12.121212... minus 0.121212... would just be 12. This is because if we know that all the numbers behind the decimal point is 0.121212 and so on, 12.121212... minus 0.121212... the numbers behind the decimal would cancel out. So we are left with 12. So NO, the answer for 99x is NOT a repeating decimal.
