Answer:
3x+45=180
3x=180-45
3x=135
x=45
Step-by-step explanation:
180=2x+45+x
180=3x+45 (combine like terms)
135=3x (subtract 45 from both sides)
45=x (divide both sides by 3)

In your own words, describe how to find the GCF for a set of numbers. Use the numbers 24 and 32 as an example.
Answers
Answer:
4
Step-by-step explanation:
First, you would have to prime factorize both of the numbers. The prime factorization of 24 is 24 = 2*2*3*3, and the prime factorization of 32 is 32 = 2*2*2*2*2 or 2^5. After that, you would find what is most common:
24 = 2*2*3*3
32 = 2*2*2*2*2
What is common is that there is two 2's in each equation. 2*2 is 4, so the answer is 4.

An artist’s canvas has sides measuring 3x – 3 and 4x + 1 inches.
What is the area of the canvas? Show all work.
The artist laid the canvas flat on the floor and poured some paint in the center. The paint flows at a rate of r(t) = 4t where t represents time in minutes and r represents how far the paint is spreading on the canvas. The area of the paint can be expressed as A[r(t)]= πr². What is the area of the circle created by the paint?
If the artist wants the circle to be at least 1300 in², will it be that large in 5 minutes? Support your answer with your work.
Answers
Step-by-step explanation:
Finding the area of the canvas:
The canvas has sides measuring 3x - 3 and 4x + 1 inches. To find the area, we multiply the lengths of the sides. So, the area of the canvas is given by:
Area = (3x - 3) * (4x + 1)
= 12x^2 + x - 3
Therefore, the correct equation for the area of the canvas is A = 12x^2 + x - 3.
Finding the area of the circle created by the paint:
The rate at which the paint is spreading on the canvas is given by the function r(t) = 4t, where t represents time in minutes and r represents how far the paint has spread. The area of the circle created by the paint can be expressed as A[r(t)] = πr^2, where r(t) is the distance the paint has spread at time t.
Substituting the value of r(t) = 4t into the formula, we get:
A[r(t)] = π(4t)^2
= 16πt^2
Therefore, the area of the circle created by the paint is 16πt^2.
Determining if the circle will be at least 1300 in² in 5 minutes:
To check if the area of the circle will be at least 1300 in² in 5 minutes, we substitute t = 5 into the equation for the area:
A[r(5)] = 16π(5)^2
= 400π
Approximating the value of 400π, we get approximately, 1256.64.
Since 1256.64 is less than 1300, we can conclude that the area of the circle created by the paint after 5 minutes will not be at least 1300 in².
A = (3x - 3)(4x + 1)
A = 12x² - 8x - 3
The paint is spreading at a rate of r(t) = 4t, which means that the radius of the circle is also increasing at a rate of 4t. Therefore, the area of the circle can be expressed as:
A[r(t)] = πr²
A[r(t)] = π(4t)²
A[r(t)] = 16πt²
We want to find out if the area of the circle will be at least 1300 in² in 5 minutes. So we need to substitute t = 5 into the equation for the area of the circle:
A[r(5)] = 16π(5)²
A[r(5)] = 400π
The area of the circle created by the paint after 5 minutes is 400π in², which is approximately 1256.64 in². Since this is less than 1300 in², the circle will not be that large in 5 minutes.

Cecile packages snack mix at a health food store.
She uses 13 of her supply of sunflower seeds to make a salted snack mix and 29 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?
Answers
Answer:her supply has 18 pounds
Step-by-step explanation:Assume that the number of pounds in her supply is x.
We are given that:
She uses 1/3 x in salted mix and 2/9 x in unsalted mix.
This means that:
Total amount used = 1/3 x + 2/9 x = 5/9 x of her supply
Now, we are also given that:
She used 10 pounds of her supply.
This means that:
5/9 x = 10
5x = 9*10 = 90
x = 18 pounds

second answer: y = 5x + 120; $180
Step-by-step explanation:
he starts with $120.
so, whatever else he does per month, there will always be the $120 starting amount to be added.
so, the third and the fourth answers are out.
then think : $5 every month.
that is how much after 2 months ? 2×5 = $10.
how much after 3 months ? 3×5 = $15.
so it has to be an equation that contains 5x (5 times the number of months).
combining both thoughts :
y = 5x + 120
now let's use x = 12 (for 12 months = 1 year).
5×12 + 120 = 60 + 120 = $180.
yes, it is that simple. no hidden "hocus pocus" is needed. just common sense.

Step-by-step explanation:
For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.
