Answers
45(x)-20
x=hours
7 hours
x=7
45(7)-20 =295
Answer:
y = 45(7) - 20
Step-by-step explanation:
Money earned: 45x.
Money spent: 20
Total money: 45x-20
In this case, if he worked 7 hours, he would make a total of 45(7)-20, or 295 dollars for the day.

On graph paper, draw diagrams of a+a+a+a and 4a when a is 1, 2, and 3. What do you notice?
Answers
When the value of a will be 2 and 3 from 1, The square formed will be dilated by a scale factor of 2 and 3.
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
We know, A square has side lengths that are equal to each other.
Given, We draw a diagram of a + a + a + a, This will form a square.
Now, When the values of a will be 1 we will have a square with side
lengths 1.
Now, When a = 2 and a = 3 the square will be dilated by a scale factor of 2 and 3.

The Middle school team scored three field goals worth three points each and two touchdowns worth six points each, Including extra points. Write a numerical Expression to find the team's score.
Answers
21
Step by step explanation:
So, what we know is that we have 3 field goals, each worth 3 points, and 2 touchdowns, each worth 6 points. So we can do: 3 * 3 + 2 * 6. To break this down we first must do 3 * 3. This gets us an answer of 9, we then must do 2 * 6. Which gives us an answer of 12. Now that we have multiplied the 2, we may add, 9 + 12 = 21. Meaning our answer is 21. I hope this helped you out!

Paul is 11 and 5/6 years old.
Greg is 1 and 1/3years younger than Paul,
and Jane is 1 and 1/4 years younger than Greg.
How old is Jane?
Answers
Answer:
How old is jane she is 9 and 1/4
Step-by-step explanation:
So we know that paul is 11 and 5/6
and greg is 1 and 1/3 younger than paul
and jane is 1 and 1/4 younger than greg
First we got to the great common factor of the three facrtion
its 12
so paul is 11 and 10/12
greg is 1 and 4/12
jane is 1 and 3/12
subtract paul age to gregs which is 10 and 6/12 simpfly to is 10 and 1/2
the subtract gregs age to janes which is 9 and 3/12 simply is 9 and 1/4
A roll of ribbon was 12 meters long. Diego cut 9 pieces of ribbon that were 0.4 meters each to tie some presents. He then used the remaining ribbon to make some wreaths. Each wreath required 0.6 meter.
How many meters of ribbon were available for making wreaths?
_____ meters
How many wreaths could Diego make with the available ribbon?
_______wreaths
Answers
Answer: 8.4; 14.
Step-by-step explanation:
To find how much ribbon we used to tie presents, we need to multiply 9 and 0.4.
9 x 0.4 = 3.6.
Diego used 3.6 meters of yard to tie some presents. We can subtract that from 12 to find how much ribbon we have left.
12 - 3.6 = 8.4.
We have 8.4 meters of ribbon to make wreaths.
Now we have to find how many wreaths we can make wiht 8.4 meters of ribbon. We know that each wreath needs 0.6, so we should divide 8.4 by 0.6 to find how many wreaths we can make.
8.4 ÷ 0.6 = 14.
Therefore, we can make 14 wreaths with the 8.4 meters of leftover ribbon.
(Part A's answer is 8.4, and Part B's answer is 14)
We start off with 12m
Since there are 9 ribbons each 0.4 meters you have to do 9 • 0.4. Since that is 3.6m.
To find out how much ribbon you have left you must subtract the amount he used against the amount he had to begin with.
12 - 3.6 = 8.4
To find out how many wreaths he can make, you must divide the remaining amount of ribbon he has by the 0.6 meter.
8.4 divided by 0.6 is 14.
Answer:
He can make 14 wreaths with the remaining amount of ribbon.

Answer:
The expression you provided involves a limit, a summation, and variables. To provide a clear and concise answer, I will break down the components of the expression and explain their meaning.
1. lim (0 to 100): This notation represents the limit as a variable approaches a certain value. In this case, the variable is not specified, so I will assume it represents the value of M.
2. Σ (k=1 to n): This symbol represents a summation, where the variable k takes on values from 1 to n. The value of n is not specified in the expression you provided, so I cannot calculate the exact summation.
3. In n: I'm not sure what "In n" refers to in this context. It could be a typo or an incorrect notation. Can you please clarify or provide more information?
Based on the information provided, I can explain how to evaluate a general expression involving a limit and a summation.
To evaluate the expression, follow these steps:
1. Determine the values for M and n. These values may be provided in the problem or given as part of the context.
2. Plug in the values of M and n into the expression.
3. Evaluate the summation by substituting k with the values from 1 to n and summing up the results.
4. Finally, take the limit as M approaches the specified value, if applicable.
If you provide more information or clarify the meaning of "In n," I can provide a more specific answer.
