Fourteen students are surveyed about the books they read. Four students read only science fiction books. Three students read only fantasy books. Five students do not read science fiction or fantasy. How many students read both science fiction and fantasy?

Answer: 8x8x8=512

Step-by-step explanation:

The output variable B (total number of beads needs for each necklace) equals 27 (number of spacers used) plus 5 times the input variable A (length of the necklace in inches). The resulting equation is B = 27 + 5A.

In this question, we're trying to find out the total number of beads Li needs to create each necklace.

Let's define two variables:

Li uses 27 spacers for each necklace regardless of its length and there are 5 beads for every inch of necklace. Given these facts, we can create an equation as follows:

B = 27 + 5A

In this equation, 27 is the number of spacers used, while 5A indicates that 5 beads are strung for each inch of the necklace.

To use this equation, simply replace the variable 'A' with the desired length of the necklace in inches. The result will give the total number of beads Li needs for that particular length of necklace.

Final answer:

Points on the line 3x+5y=15 which are equidistant from the coordinate axes are (15/8, 15/8) and (-15/8, -15/8).

Explanation:

To find points on the line 3x+5y=15 that are equidistant from the coordinate axes, we need a point where the x and y coordinates are equal because the distances to the x-axis and y-axis from any point (x, y) are |x| and |y|, respectively. Since the line is equidistant from both axes, we require |x| = |y|.

Substituting y for x in the equation of the line, we get 3x + 5x = 15, which leads to 8x = 15, and therefore x = 15/8. Since we are looking for points equidistant from the axes, we have to check the signs of x and y to ensure they are at equal distances from both axes. Thus, the possible points are (15/8, 15/8) and (-15/8, -15/8).

Step-by-step explanation:

The given statement is true"If two angles share a vertex then they are adjacent".

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

If two angles in geometry share a side and a vertex, they are said to be adjacent. In other words, consecutive angles do not overlap and are placed side by side.

When an angle's vertex and side are shared by another angle, the two angles are said to be adjacent angles. The vertex of an angle is the point where the rays come to a stop and form the sides of the angle. When two adjacent angles share a vertex and a side, they can be either complementary or supplementary angles.

Thus, the given statement is true"If two angles share a vertex then they are adjacent".

The total cost of the steaks that Ms. Snork brought will be $23.184.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Ms. Snork brought two steaks that weighed 2.96 lb and 3.48 lb. If the meat cost $3.60 per pound. Then the total cost of the steaks will be given as,

⇒ 2.96 x $3.60 + 3.48 x $3.60

⇒ $10.656 + $12.528

⇒ $23.184

The total cost of the steaks that Ms. Snork brought will be $23.184.

Normally I am not one to make long answers

but if you want an explanation in case you have the same question with different numers, here is an explanation

Plug in the eequation and solve for x

Doing quick math the equation would be 8y-33 = 5y+9

I plugged this into m a t h w a y and got y=14

Then I subsituted y with 14

5 x 14 = 70 70 + 9 =79

Then I did a double check by making sure they were both equal

8 x 14 = 112   112 - 33 = 79

79 = 79

Therefore your answer is 79

Hope this helped, have a great day :)

Answer: [tex]\angle{J}=100^{\circ}[/tex]

Step-by-step explanation:

Given: △ABC≅△JKL,

m∠B=55°, and m∠L=25°

We know that if two triangles are congruent then their corresponding angles are equal.

∴ m∠A=m∠J

m∠B=m∠K=55°

m∠C=m∠L=25°

Now, by angle sum property in triangle JKL we have

[tex]\angle{J}+\angle{K}+\angle{L}=180^{\circ}\\\\\Rightarrow\angle{J}+55^{\circ}+25^{\circ}=180^{\circ}\\\\\Rightarrow\angle{J}=180^{\circ}-55^{\circ}-25^{\circ}\\\\\Rightarrow\angle{J}=100^{\circ}[/tex]

The two numbers whose difference is 168 and whose product is a minimum will be -50 and 50.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, two numbers whose difference is 168 and whose product is a minimum.

Suppose the two numbers are x and Q respectively.

If x - Q = 100, then Q = 100 + x

The function of their product is minimum,

F(x) = xQ

F(x) = x (100 + x)

F(x) = x² + 100x

Find the equation's lowest point on a graph. At x, the lowest point is -50,

f(x) = -2500

If,

Q = 100 + x

Q = 100 + (-50)

Q= 50

The product of the number is,

xQ = 50 × -50

xQ = -2500

Thus, the two numbers whose difference is 168 and whose product is a minimum will be -50 and 50.

To determine if two lines are perpendicular, we can calculate their slopes. The line through P(1,9) and Q(9,6) has a slope of -3/8, and the line through R(-6,0) and S(-9,8) has a slope of -8/3. The product of these slopes is -1, indicating that the lines are perpendicular.

To determine whether the line through points P(1,9) and Q(9,6) is perpendicular to the line through points R(-6,0) and S(-9,8), we can calculate the slope of each line. The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula: slope = (y2 - y1) / (x2 - x1).

For the line through P(1,9) and Q(9,6), the slope is (6 - 9) / (9 - 1) = -3/8.

For the line through R(-6,0) and S(-9,8), the slope is (8 - 0) / (-9 - (-6)) = 8/-3 = -8/3.

If the two lines are perpendicular, the product of their slopes should be -1. Let's check: (-3/8) * (-8/3) = 1. Therefore, the line through points P(1,9) and Q(9,6) is perpendicular to the line through points R(-6,0) and S(-9,8).

Final answer:

Jim originally had $713 in his wallet before purchasing the TV. We found this by setting up the equation x - $576 = $137, which represents the situation before and after the purchase, and solving for x.

Explanation:

Jim bought a $576 TV with the cash in his wallet and now has $137 left. To find out how much money Jim originally had, we can write and solve a simple equation. Let's denote the amount of money Jim originally had as x. After buying the TV, he spent $576, so the money left is $137. This gives us the equation x - $576 = $137.

To solve for x, we add $576 to both sides of the equation, which gives us x = $137 + $576. Therefore, x = $713. So, Jim originally had $713 in his wallet before buying the TV.
