how to check : 3x+5=11

Answers

Answer 1

Answer:

There are two ways to check if 3x+5=11 is true:

Subtract 5 from both sides of the equation. This will isolate x on the left-hand side of the equation.

3x = 6

Divide both sides of the equation by 3. This will divide both sides of the equation by 3, which will cancel out the 3 on the left-hand side of the equation, leaving x by itself.

x = 2

You can also check if 3x+5=11 is true by plugging in 2 for x. If you do this, you will get 3(2)+5 = 6+5 = 11. Therefore, 3x+5=11 is true when x=2.

Answer 2
Subtract 5 from both sides

The number of cookies that were made at a bakery for each of seven days is shown:

108, 96, 96, 84, 108, 240, and 84


The best measure of center for this data set is the-


A: median because all of the values are close to one another in value


B: mean because all of the values are close to one another in value


C: median because 240 is much higher than the other numbers in the data set


D: mean because 240 is much higher than the other numbers in the data set

Answers

To determine the best measure of center for the given data set, we need to consider the values and their distribution.

The data set is as follows: 108, 96, 96, 84, 108, 240, and 84.

The median represents the middle value when the data set is arranged in ascending or descending order. In this case, when we arrange the data in ascending order, we have: 84, 84, 96, 96, 108, 108, 240. The middle value is 96, which is the fourth value in the sorted data set.

The mean is calculated by summing up all the values and dividing by the total number of values. In this case, the sum of the values is 756 (108 + 96 + 96 + 84 + 108 + 240 + 84), and there are seven values. Therefore, the mean is 756/7 = 108.

Comparing the options:

A: median because all of the values are close to one another in value - This is not accurate as the values vary, and the median is not necessarily the best measure of center based on the values being close to one another.

B: mean because all of the values are close to one another in value - This is not accurate as the values are not all close to one another, and the mean is not necessarily the best measure of center based on the values being close to one another.

C: median because 240 is much higher than the other numbers in the data set - This is not accurate as the presence of a single high value does not automatically make the median the best measure of center.

D: mean because 240 is much higher than the other numbers in the data set - This is the most accurate option. The mean takes into account the magnitude of each value and is influenced by extreme values. The value 240 has a significant impact on the mean, making it a better measure of center in this case.

Therefore, the best measure of center for this data set is D: mean because 240 is much higher than the other numbers in the data set.
The median is the middle number as in lowest to highest

Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?

Answers

Answer:

Let's start by using variables to represent the ages of the three people:

Let L be Liz's age.

Let D be Debbie's age.

Let F be Freya's age.

From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:

L = (2/3)D

We also know that Debbie's age is half of Freya's age, so we can write:

D = (1/2)F

To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:

F = 2D

Now we can substitute this expression for F into the equation for Liz's age:

L = (2/3)D = (2/3)(1/2)F = (1/3)F

So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

The ratio of Liz’s age to Freya’s is 1:3

\(8x+6=x+1\)

\(8x-x=1-6\)

\(7x=-5\)

\(x=\frac{-5}{7}\)

Answer:

x = -5/7

Step-by-step explanation:

2(4x+3)=x+1

Distribute

8x +6 = x+1

Subtract x from each side

8x+6-x = x+1-x

7x+6 = 1

Subtract 6 from each side

7x+6-6 = 1-6

7x =-5

Divide each side by 7

7x/7 = -5/7

x = -5/7

If there are 2 red balls, 2 blue balls, and 4 green balls in a pail, what is the probability of pulling out a green ball?

(step-to-step pls)

Answers

Answer:

Step-by-step explanation:

Step 1 is to find the total number of balls in the pail.

There are 8 balls in total

Now that you know there are 8 balls, you have to find out how many of those 8 are green. This is because you want to pull out a green ball. You would do the same thing for any other colored ball.

Since 4 out of the 8 balls in the pail are green, you can write this as 4/8

The last step is to simplify to get 1/2 which in other terms is 50%.

So the probability of you pulling a green ball is 50%

It’s 50 percent chance of pulling out a green ball.

A recipe calls for 1 3/4 cups of milk for 8 servings. If the recipe is increased to 24 servings, how much cups of milk are needed?

Answers

Assuming there is the same amount of cups of milk per serving.

Answer:

\(5~1/4\)

Step-by-step explanation:

When we increase from \(8\) servings to \(24\) servings, we triple the amount of servings needed, and hence we triple the amount of ingredients needed.

So, the amount of cups of milk needed is \(3(1+3/4)=3+9/4=3+2~1/4=5~1/4\).

So, the answer is \(\boxed{5~1/4}\) and we're done!

The number of cups of milk needed for the recipe is 5 1/4 cups.

What is Proportion?

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s. If both these ratios are proportional, then we can write it as  p : q = r : s.

Given that,

A recipe calls for 1 3/4 cups of milk for 8 servings.

We have to find the number of cups of milk needed for 24 servings.

The ratio of the number of cups of milk to the number of servings will be equal.

Let x be the number of cups of milk needed for 24 servings.

1 3/4 cups = 7/4 cups

Using proportion,

7/4 / 8 = x / 24

8x = 7/4 × 24

8x = 42

x = 42 / 8

  = 21 / 4

  = 5 1/4 cups.

Hence the number of cups needed for 24 servings is 5 1/4 cups.

Because 8+8+8+6+7+5=42
Then divide that by 6 to get the mean - so 42/6=7 so that’s the correct mean
5 points

Explanation:
Mean = average
Equation: total points scored/total players
Mean=7+8+6+8+?+8/6

The mean is given: 7

So plug it in:
7=(7+8+6+8+?+8)/6

Factor to solve:

Add all the numbers together to leave just the missing number (?)
7=(37+?)/6

To get rid of the 6 multiply it over to the other side
6x7=37+?
42=37+?

Now subtract the 37 to the other side to find the missing number (?)
42-37=?
5=?

Now let’s check:
7+8+6+8+(5)+8=42
Add:
42
Now divide by 6

Answer: A: 1/15

Step-by-step explanation:

A number cube has 6 sides.

the probability of getting either a 2 or a 3 will be 2/6, (since both events have an equal chance of happening, and they are out of total 6 possible outcomes).

2/6 simplifies to 1/3, so that is the probability of getting either a 2 or a 3

Next, the probability of landing on blue:

it will be 1/5, since there is only 1 blue section out of 5 *equally* divided sections.

Note that the probability includes the word "and". this means that we will use multiplication.

1/3 * 1/5 = 1/15

and thats the answer!

B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.

Which one is right and why?

Answers

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
