Final answer:
The expression for the cost of dinner plus $27 tip divided by three people is (d + 27) / 3.
Explanation:
To find an expression for the given verbal description, first write the sum of the cost of dinner d and a $27 tip. This sum is represented by the expression d + 27. Then, to divide this sum equally among 3 people, you divide the entire expression by 3. The final expression in simplest form would be (d + 27) / 3.

Write a quadratic function f whose zeros are 2 and 9 .
Substituting these values into the general form of a quadratic equation
f(x) = x² - 11x + 18
A quadratic equation is of the form:
f(x) = x² - (Sum of roots)x + (product of roots)
The given roots are 2 and 9
Sum of roots = 2 + 9
Sum of roots = 11
Product of roots = 2 x 9
Product of roots = 18
Substituting these values into the general form of a quadratic equation
f(x) = x² - 11x + 18

The difference between the mean and median of the data is 50.
What is the mean?The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.
Given:
David played a video game 5 times.
The list shows his scores:
4975,5275,4825,5100,4950.
To find the median:
The median is the value that splits the mathematical numbers or expressions in the half. The median value is the middle number of data points. To find the median, firstly arrange the data points in ascending order.
4825, 4950, 4975, 5100 and 5275.
So, the middle number is 4975.
The median is 4975.
To find the mean;
The mean = the sum of the scores / 5
The mean = 25125 / 5
The mean = 5025
The difference:
5025 - 4975 = 50
Therefore, the required difference is 50.

Three times the sum of a number and six is greater than four times the number decreased by two
Final answer:
The mathematical problem is to express 'Three times the sum of a number and six is greater than four times the number decreased by two' as an inequality, resulting in 3(n + 6) > 4n - 2, which simplifies to n < 20.
Explanation:
The question involves translating a word problem into an algebraic inequality. The problem statement 'Three times the sum of a number and six is greater than four times the number decreased by two' can be translated into the inequality 3(n + 6) > 4n - 2, where n represents the unknown number.
To solve this inequality, we would first expand the left side of the equation by distributing, resulting in 3n + 18 > 4n - 2. Then, we would get all n terms on one side and constants on the other, leading to the inequality n < 20.
Given (x – 7)2 = 36, select the values of x.
x = 13
x = 1
x = –29
x = 42
we have
[tex](x-7)^{2} =36[/tex]
square root on both sides
[tex](x-7)=(+/-)\sqrt{36}[/tex]
[tex](x-7)=(+/-)6[/tex]
[tex]x=(+/-)6+7[/tex]
[tex]x1=6+7=13[/tex]
[tex]x2=-6+7=1[/tex]
therefore
the answer is

Write an equation of the line containing the point (3,5)and perpendicular to the line 2x- 3y
Answer:
The equation of the line would be y = -3/2x + 19/2
Step-by-step explanation:
First we need to solve the original equation for y so that we can find the slope.
2x - 3y = 0
-3y = -2x
y = 2/3x
So since the equation has a slope of 2/3, we know the perpendicular slope would be -3/2 (since perpendicular slopes have opposite and reciprocal slopes). Then we can use this and the ordered pair in point-slope form.
y - y1 = m(x - x1)
y - 5 = -3/2(x - 3)
y - 5 = -3/2x + 9/2
y = -3/2x + 19/2
