There were 5 people who bought tickets to a football game. They bought 3 tickets each. How many tickets were bought in all?

Answers

5 people times 3 tickets each
5 times 3 = 15

15 tickets in all
So basically you want to say,

five people who each bought 3 tickets

Or, 

five groups of 3 tickets.

So five groups of 3 tickets would be,

3 + 3 + 3 + 3 + 3,

or 3 * 5.

Doug is going to the store to stock up on food for his dog. While in the store, Doug decides to buy a single bag of dog treats as well. If a large bag of dog food costs $57 and a bag of dog treats costs $9, how many large bags of dog food, x, did Doug buy if he spent $180 and all prices already include sales tax?

Answers

WELL if he only bought a single bag of treats we just need to subtract $9 from his total amount spent, then we can just worry about how many bags of dog food he bought.

180 - 9 = 171

If each bag of dog food costs $57 then we just divide it with the remaining total.

171 / 57 = 3


WHICH MEEEAANNNS:

Doug bought 3 bags of dog food. c:

Final answer:

To find the number of large bags of dog food Doug bought, use the given prices and total spent in the store.

Explanation:

Doug bought 3 large bags of dog food.

To solve this problem, we can set up the equation: $57x + $9 = $180. From here, we can find x by rearranging the equation to solve for x.

Therefore, Doug bought 3 large bags of dog food, as each large bag costs $57 and he spent $180 in total.

To change from one unit to another in the metric system, multiply or divide by multiples of (answer).

Answers

You can change from one unit to another in the metric system by multiplying or dividing by multiples of 10. For example, to convert centimeters into decimeters, you divide the number of centimeters by 10. To convert meters into decimeters, you multiply the number of meters by 10. One advantage of the metric system is that conversion between units is easier than in systems of measurement that require memorizing more complicated conversions.

You are going running. For every mile you run, you burn 100 calories. In the equation below, m represents the number of miles you run, and c represents the number of calories you burn. The relationship between these two variables can be expressed by the following equation: c=100m, equals, 100, m Identify the dependent and independent variables.

Answers

The number of miles you run is Independent and the calories you burn is Dependent

Answer:

C is the dependent variable  

m is the independent variable

Step-by-step explanation:

 For every mile you run, you burn 100 calories. In the equation below, m represents the number of miles you run, and c represents the number of calories you burn

C= 100m

Number of calories burn depends on the number of miles you run

So calories C depends on the miles 'm'

C is the dependent variable because it depends on the value of 'm'

m is the independent variable

(5, 3) and (8, -2) Write the standard form of the equation of the line that passes through the given points.

Answers

slope = (y2 - y1) / (x2 - x1)
(5,3)...x1 = 5 and y1 = 3
(8,-2)..x2 = 8 and y2 = -2
now we sub

y = mx + b
slope(m) = -5/3
use either of ur points..(5,3)...x = 5 and y = 3
now we sub and find b, the y int
3 = -5/3(5) + b
3 = -25/3 + b
3 + 25/3 = b
9/3 + 25/3 = b

jack has a 8-ft long board. he cut off 1/6 of it how long is the remaining piece in feet and inches

Answers

First, let's find out the equivalent amount of one-sixth of the total length of 8 ft.

Length of cut = 8(1/6) = 4/3 ft

So, the remaining length would be:
Remaining length = 8 ft - 4/3 ft = 20/3 ft or that's 6 and 2/3 ft.

Since there are 12 inches in 1 ft:
2/3 ft * 12 in/ft = 8 inches

Thus, the remaining length is 6 ft and 8 inches.

Write an equation for the vertical translation. y=1/2x; 18 units down

Answers

Final answer:

To write an equation for a vertical translation, subtract the amount of the translation from the original equation. In this case, the equation y = 1/2x becomes y = 1/2x - 18, representing a vertical translation of 18 units downwards.

Explanation:

To write an equation for the vertical translation, we start with the equation y = 1/2x. Since we need to shift the graph 18 units down, the equation becomes y = 1/2x - 18. This equation represents a vertical translation of 18 units downwards.

A = bh; A =96, b = 12 What does h equal?

Answers

Final answer:

To find the height h, divide the area A (96) by the base b (12) to get h = 8.

Explanation:

The problem statement A = bh is a formula to calculate the area of a rectangle, where A is the area, b is the base or width, and h is the height. You're given that the area A is 96 and the base b is 12; you need to find the height h. You can rearrange the formula to solve for h by dividing both sides by b:

h = A / b.

Plug in the values that you know:

h = 96 / 12 = 8.

So, the height h equals 8.

Now that we have the first number, we look to the 10s and the powers they are raised to. Since we are looking at powers of the same number, we can use the properties of exponents to simply subtract the numbers they are raised to.

Please help me :/ If AB=BC, then DE=2(AB). AB=6 and BC=6. What can you conclude

Answers

Final Answer:

Given AB = BC = 6, and DE = 2(AB), then DE = 2 * 6 = 12. Therefore, DE equals 12 units.

Explanation:

In the problem, it's stated that AB = BC = 6 units. This means that both AB and BC are equal in length, each measuring 6 units. As per the given relationship, DE is twice the length of AB. Substituting the known value of AB as 6 units into the expression for DE, we get DE = 2 * 6 = 12 units.

The equality of AB and BC implies that the triangle ABC is an isosceles triangle, where AB and BC are the congruent sides. Consequently, the line segment DE, which is related to AB, shares the same length as BC, making DE also equal to 6 units. However, as per the given relationship DE = 2 * AB, DE is calculated as 2 times the length of AB. Substituting AB = 6 units into the equation, DE = 2 * 6 = 12 units.

Therefore, following the given relationship between DE and AB and using the fact that AB = BC, we can confidently conclude that the length of DE is 12 units. This is determined by doubling the known length of AB, which is established by the equality of AB and BC in the context of an isosceles triangle.

Ninety one students signed up for the skating club. Coach Link wants to form teams with the same number of members on each team, but says that is impossible: the only teams he can make are 91 teams of 1 or 1 team of 91. Is coach Link correct. Explain why or why not.

Answers

Actually I believe that Coach Link is incorrect in saying that he can only make 91 teams of 1 or 1 team of 91.

To find the number of teams he can make, we have to find the whole number that can divide 91 and give also a whole number answer. In this case, I found it to be 7.

91 / 7 = 13

So this means that Coach Link can also make 7 teams of 13 or 13 teams of 7.

[tex]2w^{2}-3w=A-12[/tex]
[tex]2w^{2}-3w+12=A=l*w=2w*w=2w^{2}[/tex]

Is 4x + the square root of y = 12 a linear function

Answers

I wouldn't say so, as if you rearrange that equation you get sqr root y = 12 - 4x. Then you square everything to get the value of y so you would end up with 144 - 16x^2.
Therefore, the x value has a power, so it would be a curved line
Final answer:

The equation 4x + √y = 12 is a non-linear function because of the square root term. Non-linear functions do not have a constant rate of change and their graphs are not straight lines.

Explanation:

The equation 4x + √y = 12 is not a linear function. A linear function is defined as a function that can be represented by a straight line. However, this equation contains a square root term, which makes it a non-linear function. To determine the type of function, it is important to consider the rules and properties of different function types.

In this case, the equation represents a non-linear function because of the square root term. Non-linear functions do not have a constant rate of change and their graphs are not straight lines. The square root term introduces a curve in the graph.

For example, let's say y = 4, then we can solve for x: 4x + √y = 12, which simplifies to 4x + 2 = 12. Solving for x, we get x = 2. So, for y = 4, x = 2. If we continue to substitute different values for y, we will see that the relationship between x and y is not linear.
