Answer:
-3x + 549
Step-by-step explanation:
The order of operations is PEMDAS(parenthesis, exponents, multiplication, division, addition, subtraction)
So, according to PEMDAS, the first thing that we would do is solve the parenthesis. Since we can't solve the parenthesis because they aren't like terms, we're going to use distributive property to solve it instead.
-3(x+8) = -3(x) + -3(8) = -3x -24
Now we have: -3x - 24 ^ 2 -3
Our next step is to solve the exponent
24 ^ 2 or 24 x 24 = 576
Now we have: -3x - 24 + 576 -3
Our next step would be to add and subtract the like terms
-24 + 576 = 552 and 552 - 3 = 549
Now we have: -3x + 549
This would be the simplest form of the equation because -3x and 549 are not like terms

At the movie theatre, child admission is $5.10 and adult admission is $8.90. On Sunday, 156 tickets were sold for a total sales of $1145.20. How many child tickets were sold that day?
let y = number of child tickets so the total 0f 34 child tickets is sold at that day.
Define substitution.To calculate an expression's value by substitution, integers are substituted for letters in the expression.
Define expression.Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
let x = number of adult tickets
let y = number of child tickets
x = 4y (four times as many adult tickets as child tickets
8.4x + 5.1y = 1315.8
but we can substitute 4y for x
8.4(4y) + 5.1y = 1315.8
33.6y + 5.1y = 1315.8
38.7y = 1315.8
y = 34 and x = 4Y
x = 136

How do you know if its linear or linear?
Linear equations are equations that can be written in the form ax + b = c, where a, b, and c are real numbers and a ≠ 0.
The equation can be solved for the variable x by subtracting b from both sides and then dividing both sides by a. This will give the solution for x, which is x = (c - b) / a.
For example, consider the equation 2x + 4 = 10. This is a linear equation since it can be written in the form ax + b = c, where a = 2, b = 4, and c = 10. To solve for x, subtract b from both sides to get 2x = 6, and then divide both sides by a to get x = 3. Therefore, the solution to the equation is x = 3.

When can parallelism make your algorithms run faster when could it make your algorithms run slower?
When an algorithm necessitates extensive sharing of instantaneous results, parallelism slows it down. Because there are multiple independent parallel processes and the right number of threads, parallelism will speed up an algorithm.
What algorithm is parallelizable?The ones with data dependencies are the most challenging. It will be exceedingly challenging, for instance, if you are dealing with a vector and the input for the computation at point n depends on the output at position n-1.
When this occurs, you must comprehend what the original algorithm is doing and take an alternative approach. For the aforementioned case, it might be a difficulty with digital signal processing including a feedback-containing digital filter. These are challenging to parallelize, but that is not the sole solution. Instead, you might use the filter and signal's fast Fourier transforms, multiply them, and then perform the inverse transform. All of these operations can be partially parallelized.

i'm stuck on this question! solve for x. assume that lines which appear tangent, are tangent.
Answer:
7
Step-by-step explanation:
The formula for intersecting chords creating which create the limits of arcs and associated angles is
<HES = 1/2 (ARC HS + ARC GF)
<HES = 1/2 (ARC 51 + ARC 195)
<HES = 1/2 (246)
<HES = 123
What that tells you is that <GEF = the same thing because <HES and <GEF are vertically opposite.
Now I am going to assume that <HES = 16x + 11. This is not a sure thing, but I assume it is what is intended.
16x + 11 = 123 Subtract 11 from both sides
16x = 123 - 11
16x = 112 Divide by 16
x = 112/16

A 12 pack of soda cost $4.80. What is the unit cost?
Answer:The cost of each can is $ 0.31
.
Step-by-step explanation: You need to take the amount of money each pack costs and divide it by the number of cans to find the unit rate. Hope this helps!!
brianlist please ?
To find the unit cost, simply divide the amount of money by the amount.
4.80÷12= 0.4 dollars
So each soda is only 0.4 dollars.
How can you check this?
0.4 dollars times 12 should equal the total cost of soda.
0.4x12=4.80, so it's correct.

What is the coefficient of y2 in the expression 2x2y 15xy2 7y?
Let x be the coefficient of y^2 in the expression 2x^2y+15xy^2-7y. So x=0.
What is co-efficient?
A coefficient is a multiplicative factor in a polynomial, series, or expression in mathematics. It is typically a number, although it can also be any expression (including variables such as a, b and c). They may also be referred to as parameters if the coefficients are variables in and of themselves.
Write an example of co-efficient.
As an illustration, 6z stands for 6 times z. Since z is a variable, 6 is a coefficient. For variables without a value, the coefficient is 1.
The given algebraic expression is 2yx^2+15xy^2-7y.
The terms are xy^2, yx^2 any y^2
So the co-efficient of y^2 is 0

Nevaeh earned a score of 850 on Exam A that had a mean of 550 and a standard deviation of 100. She is about to take Exam B that has a mean of 36 and a standard deviation of 10. How well must Nevaeh score on Exam B in order to do equivalently well as she did on Exam A? Assume that scores on each exam are normally distributed.
Nevaeh's score in Exam A of 850, where the mean and standard deviation are 550, and 100, indicates, using the z-score, that in Exam B with a mean and standard deviation of 36 and 10, respectively, her score should be 66.
What is a z-score?A z-score is an indication of the number of standard deviations, a data point is from the mean.
The score Nevaeh earned in Exam A, x₁ = 850
The mean score for Exam A, μ₁ = 550
The standard deviation for Exam A, σ₁ = 100
The mean score for Exam B, μ₂ = 36
The standard deviation for Exam B, σ₂ = 10
A quantity that can be used to evaluate Nevaeh's score for Exam A is the z-score, which can be expressed as follows;
[tex]z = \dfrac{x - \mu}{\sigma}[/tex]
Nevaeh's z-score for Exam A is therefore;
[tex]z = \dfrac{850 - 550}{100} =3[/tex]
Nevaeh's performance on Exam B in order for her to do equivalently well as she did on Exam A is obtained by using a z-score of 3 for her performance in Exam B as follows;
[tex]z = 3 = \dfrac{x_2 - 36}{10}[/tex]
3 × 10 = x₂ - 36
30 = x₂ - 36
x₂ = 30 + 36 = 66
Nevaeh's score on Exam B should be 66 in order for her to perform equivalently well as she did in Exam A

Find C using Special right triangles
The length c of the right angle triangle is 9 units.
How to find the side of a right triangle?A right angle triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a right angle triangle is 180 degrees.
The sides of a right angle triangle can be found using trigonometric ratios as follows:
Therefore,
sin 60° = opposite / hypotenuse
where
opposite side = c
hypotenuse side = 6√3 ft
Hence,
sin 60° = c / 6 √3
cross multiply
c = 6√3 × sin 60
c = 6√3 × √3 / 2
c = 6 × 3 / 2
c = 18 / 2
Therefore,
c = 9 units
