Part B: Name one property you used to solve this equation. (4 points)
Answers
hope it helps you!!!!!!!!!!!!!!
Start with
[tex]8x+2(x-7)=7x+3x-14[/tex]
Apply the distributive property to expand the left hand side:
[tex]8x+2x-14=7x+3x-14[/tex]
Sum like terms:
[tex]10x-14=10x-14[/tex]
Apply the additive property of equality to add 14 to both sides:
[tex]10x=10x[/tex]
Apply the additive property of equality to subtract 10x to both sides:
[tex]0=0[/tex]
This means that the equation was actually an identity, i.e. the left and right hand sides were actually the same expression.
Since they are the same expression, it doesn't matter which values you plug into x, it will always be a solution of this equation.
Solution: infinite. All numbers are solutions of this equation.

`Judith is 5 years younger than Trina and 5 years older than Gretchen. The average of their ages is 23. How old is each Woman?
Answers
Answer:
Gretchen: 18
Judith: 23
Trina: 28
Step-by-step explanation:
Do reverse math. to find the average you would normally add up each age and divide your answer by the amount of ages provided. but in this case we don't have enough information so you do it opposite.
23x3=69.
Trina is clearly the oldest and Gretchen is the youngest, leaving Judith in the middle.
Gretchen: 18
Judith: 23
Trina: 28
it takes some experimenting with numbers but this is correct because all three numbers add up to 69 and they are each 5 years apart.

Answers
Answer:
Number of cookies produced in 8 hour are 10,600 cookies.
Step-by-step explanation:
If the production rate of cookies in a bakery is 1325 cookies per hour, we need to tell how many cookies will be produced in 8 hour shift.
Number of cookies produced in 1 hour = 1325 cookies
Number of cookies produced in 8 hour = 1325 * 8
= 10,600 cookies.
So, Number of cookies produced in 8 hour are 10,600 cookies.

Harry wanted to know the amount of hours that his classmates spent doing homework on any given
night. He surveyed his classmates and received the following data set.
.5, .5, .75, .75, .75, 1, 1, 1, 1, 1.5, 1.5, 2, 2, 3, 4
What is the interquartile range of the data set that Harry collected?
Answers
Answer:
1.25
Step-by-step explanation:
Hopefully that's right. It's a bit hard to see separation
The interquartile range of Harry's collected data set is 1.25 hours.
To calculate the interquartile range (IQR) for the given data set, we must first arrange the data in ascending order, which is already done in this case. The data set is .5, .5, .75, .75, .75, 1, 1, 1, 1, 1.5, 1.5, 2, 2, 3, 4. The next step is to find the medians of the lower and upper halves of the data set to locate the first quartile (Q1) and the third quartile (Q3).
Since the data set has 15 numbers, the median (which is also Q2) would be the 8th value, which is 1.
For Q1, we take the lower half, which consists of the first 7 numbers. The median of this subset is the fourth value: 0.75.
For Q3, we consider the upper half, which consists of the last 7 numbers. The median of this subset is the fourth value: 2.
Now, calculate the IQR by subtracting Q1 from Q3: IQR = Q3 - Q1 = 2 - 0.75 = 1.25.
Therefore, the interquartile range of the data set that Harry collected is 1.25 hours.
Ricky is filling an 8-inch by 4-inch by 4 1/2 inch rectangular box with cubes.the cube come in two different sizes, 1 cubic inch and 1/8 cubic inch.he uses some of each size cube and he packs the box so there are no gaps.what is the least smaller subs that Ricky can use
A.)32
B.)64
C.)128
D.)256
Answers
To fill the rectangular box with cubes, Ricky can use 144 larger cubes and 0 smaller cubes, resulting in the least number of smaller cubes being 0. The correct answer is option A) 32.
Explanation:To find the least number of smaller cubes that Ricky can use to fill the rectangular box, we first need to calculate the volume of the box. The volume of the box can be found by multiplying its length, width, and height. In this case, the volume is 8 inches x 4 inches x 4.5 inches = 144 cubic inches.
The larger cubes have a volume of 1 cubic inch, while the smaller cubes have a volume of 1/8 cubic inch. To minimize the number of cubes used, we want to use the larger cubes as much as possible.
We can now calculate the number of larger cubes that can fit in the box. 144 cubic inches / 1 cubic inch = 144 cubes.
Next, we need to fill any remaining space with the smaller cubes. The remaining space can be calculated by subtracting the volume occupied by the larger cubes from the total volume of the box. 144 cubic inches - 144 cubic inches = 0 cubic inches.
Since there is no remaining space, we do not need to use any smaller cubes. Therefore, the least number of smaller cubes that Ricky can use is 0.
So, the correct answer is option A) 32.

two pens and one eraser cost 35.00 and three pencils and four erasers costs 65.00. find the cost of the pencil and eraser separately.
Answers
Answer:
Step-by-step explanation:
You start with creating let statements.
Let x = the cost of each pencil.
Let y = the cost of each eraser.
Let z= the cost of each pen.
Then, you’d fill in information from the problem.
3x + 4y = 65
2z + y = 35
Now, you’d solve like a system of equations; meaning you can do elimination or substitution.
The individual costs of pencils and erasers given total costs and quantities in a system of equations.The cost of each pencil is $2.00, and the cost of each eraser is $3.00.
The cost of each pencil is $2.00, and the cost of each eraser is $3.00.
Let x be the cost of one pencil and y be the cost of one eraser.
Set up a system of equations using the given information:
2x + y = 35 (equation 1)
3x + 4y = 65 (equation 2)
Solve the system using any method such as substitution or elimination to find x = $2.00 and y = $3.00.

The heights (in cm) and arm spans (in cm) of 31 students were measured. The association between x(height) and y(arm span) is shown in the scatterplot below. The equation of the line of best fit modeling this relationship is given.
Y=4.5x + 0.977x
Mike is 175cm tall and George is 170cm tall.
Using the model, how many centimeters longer would we expect Mike's arm span to be than George's?
____Cm
Answers
Given the line of best fit equation Y = 4.5X + 0.977, we would expect Mike's arm span to be approximately 23 cm longer than George's, assuming their respective heights are 175cm and 170cm.
Explanation:The given equation appears to have a typo, as it seems to contain two x terms, which is unusual for a line of best fit in this context. I believe it should be Y = aX + b, where 'a' represents the slope and 'b' the y-intercept.
Assuming the correct equation is Y = 4.5X + 0.977, we can calculate Mike's and George's arm spans by plugging in their respective heights (in cm) for X:
Mike's arm span = 4.5*175 + 0.977= 788.977 cmGeorge's arm span = 4.5*170 + 0.977 = 765.977 cmSo, we would expect Mike's arm span to be longer than George's by about:
788.977 cm - 765.977 cm = 23 cm

2 friends equally share 5 cookies how many cookies does each friend get?
Answers
Answer:
They both get 2 and 1/2 of a cookie!
Hope this helped, God bless you!
Final answer:
Two friends sharing 5 cookies equally will each get 2.5 cookies after dividing the total number of cookies by the number of friends.
Explanation:
If two friends equally share 5 cookies, each friend gets 2.5 cookies. Since cookies typically cannot be equally divided by 2 without cutting them into pieces, we assume here that it's possible to split the cookies such that each person gets an equal share. Here's the calculation:
Start with the total number of cookies, which is 5.
Divide that number by 2, because there are 2 friends sharing the cookies.
The answer is 2.5 cookies for each friend.
This question involves simple division and is an example of how to apply fair sharing in a real-world scenario.
What is the value of x?
Answers
Answer:
x = 71°
Step-by-step explanation:
The triangle is clearly an isosceles triangle.
We know that all interior measures of a triangle must add up to 180°.
So: 180° - 38° = 142°
Because it is an isosceles triangle, the other two missing angles must be equal.
142° ÷ 2 = 71°
Answer:
x=71
Step-by-step explanation:
Because of the side being marked 27, you know that the triangle is an isosceles triangle. That means that the other 2 angles would be congruent. To find the sum of the remaining angles, you need to subtract 38 by 180 degrees. (All of the angles in a triangle add up to 180) 180-38=142. Since we already know that the two remaining angles will be congruent, you take 142 and divide by 2 to get the final answer 71.

Unlike the US/Imperial system where there's no clear relation between an inch, a yard and a mile for example, in the metric system everything is related by the factor 10 somehow.
The unit multiplier is also used as a prefix to identify measurements. Like for meter...

Vol of cube (1/27)
Step-by-step explanation:
Approximately 108 cubes, each with side lengths of 1/3 unit, can fit into a rectangular prism that has a volume of 4 cubic units.
Explanation:The subject of this question covers volume and dimension within 3D Geometry, particularly recognizing cubic units as a measure of volume. Given a rectangular prism with a volume of 4 cubic units, which is filled with cubes, each with side lengths of 1/3 unit, the idea is to understand how many smaller cubes would fit into the larger prism.
When calculating, we first need to figure out the volume of one small cube: (1/3)^3 = 1/27 cubic units. Then, you would divide the total volume of the rectangular prism by the volume of one of the small cubes: 4 divided by 1/27. This gives approximately 108, meaning around 108 cubes with a side length of 1/3 can fit into a rectangular prism with a volume of 4 cubic units.
