Answer:
Subtracting −7n+2 from 2n−1 is 9n - 3.
Step-by-step explanation:
As the expression given in the question be as follow.
−7n+2 and 2n - 1 .
Subtracted −7n+2 from 2n - 1 .
= 2n - 1 - (-7n + 2)
Open the bracket
= 2n - 1 + 7n - 2
Simplify the above
= 9n - 3
Therefore Subtracting −7n+2 from 2n−1 is 9n - 3.
A lollipop factory used 74.75 kilograms of sugar to make 2 batches of lollipops.how much sugar did the factory put in each batch? (Tape diagram)
Each batch of lollipops contains 37.375 kilograms of sugar.
Here, we have to represent the given information using a tape diagram, we'll draw two rectangles, each representing a batch of lollipops.
The total amount of sugar used, which is 74.75 kilograms, will be divided equally between the two batches.
Now, draw the tape diagram:
Batch 1: [----] (to be determined)
Batch 2: [----] (to be determined)
Now, we know that the total amount of sugar used is 74.75 kilograms.
We need to divide this amount equally between the two batches.
Since there are two batches, we can divide the total sugar by 2 to find the amount of sugar in each batch:
74.75 kilograms / 2 = 37.375 kilograms
So, each batch of lollipops contains 37.375 kilograms of sugar.

How does radiation transfer thermal energy from the Sun to Earth?
If you have stood in front of a fireplace or near a campfire, you have felt the heat transfer known as radiation. The side of your body nearest the fire warms, while your other side remains unaffected by the heat. Although you are surrounded by air, the air has nothing to do with this transfer of heat. Heat lamps, that keep food warm, work in the same way. Radiation is the transfer of heat energy through space by electromagnetic radiation.
Answer:
Radiation transfers thermal energy from the Sun to Earth by electromagnetic waves. Electromagnetic waves can transfer energy with or without matter.

we know that
[tex]y=11+\frac{15}{x}[/tex]
where
The number of friends is -----------------------> [tex]x[/tex]
Cost of movie ticket is---------------------------> [tex]\$11[/tex]
Total cost of popcorn is-------------------------> [tex]\$15[/tex]
Jonah's portion of popcorn cost------------> [tex]\frac{\$15}{x}[/tex]
Answer:
Cost of movie ticket----- 1
Total cost of popcorn----- 15
Jonah's portion of popcorn cost------ 15/x
Step-by-step explanation:
The cost of the Jonah's costs are represented by the expression :
11+15\x
Now we have to match the expression to the explanation that they denote.
Let x be the number of friends among whom the pop-corn cost has to splitted.
As the total cost of popcorn is: 15
Hence, Jonah's portion of pop-corn is: 15/x
Also, he bought a movie ticket for 11.
Hence, the total cost that is paid by Jonah is: 11+15/x

luci cuts a board that is 3/4 yard long into pieces that are 3/8 yard long how many does she cut
Answer: She cuts 2 pieces
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Length of the board: 3/4 yard Length of the pieces: 3/8 yardSo, to calculate the number of pieces we have to divide the length of the board (3/4) by the length of each piece (3/8)
Mathematically speaking:
3/4 ÷ 3/8 = (3x8) /(4x3)=24/12= 2 pieces

What is the result of converting 1500 yards into miles? Remember that 1 mile =1760 yards
1500 yards = 0.8523 miles.
To convert 1500 yards into miles:
Given: 1 mile = 1760 yards
Divide 1500 yards by 1760 yards to find the equivalent in miles:
1500 yards ÷ 1760 yards = 0.8523 miles

Josh's chicken soup recipe calls for 2 1\2 L of chicken stock. Josh makes 3 1\4 times the recipe for a family reunion. How much chicken stock does Josh use to make soup for the family reunion? Express your answer as a mixed number in the simplest form.
Answer:
[tex]8\frac{1}{8}[/tex] L
Step-by-step explanation:
A recipe of chicken soup calls for chicken stocks = [tex]2\frac{1}{2}[/tex] L
Josh makes [tex]3\frac{1}{4}[/tex] times the recipe
= [tex]3\frac{1}{4}[/tex] × [tex]2\frac{1}{2}[/tex]
= [tex]\frac{13}{4}[/tex] × [tex]\frac{5}{2}[/tex]
= [tex]\frac{65}{8}[/tex]
= [tex]8\frac{1}{8}[/tex]
Josh would use [tex]8\frac{1}{8}[/tex] L of chicken stocks.

draw the following scenario using a vertical number line.
mary climbed up a ladder 24 feet to the second story of her house. she then climbed back down
Final answer:
To draw Mary's ascent and descent on a ladder, create a vertical number line from 0 to 24 feet to signify the height of the second story, then illustrate arrows for the ascent and descent.
Explanation:
To visualize Mary's movement on a ladder, we will draw a vertical number line. Let's assume the bottom of the ladder is at 0 feet. We will draw a number line up to 24 feet to represent the height Mary climbs to reach the second story of her house. Then, since Mary climbed back down, we would show her descent back to 0 feet. Here is how you can draw the scenario:
Start with a vertical line.Mark the bottom as 0 feet (this is where Mary starts and finishes).Mark a point at 24 feet (this is where the second story of her house is).Draw an arrow pointing up from 0 to 24 to represent Mary climbing up.Draw an arrow pointing down from 24 back to 0 to represent Mary climbing down.By following these steps, you will have a clear representation of Mary climbing up and down her ladder on a vertical number line.

the center of the circle that can be circumscribed about a scalene triangle is located by constructing the
Answer:
Circumcenter.Step-by-step explanation:
A circumscribed circle can be defined as a circle which passes throguth all three vertices of a triangle.
To construct a circumscribed triangle, first, we need to construct the circumcenter of the triangle, which is the intersection point of its all three perpendicular bisectors. Such point of intersection has equal distance to all three vertices.
Therefore, the word missing here is circumcenter.

(2n−9)−5(−2.4n+4) find the difference
Answer:
Simplified Expression: 14n - 29
Work
2n-9-5(-2.4n+4)
2n-9+12n-20
14n-9-20
12n-29
14n - 29
The difference as in the expression is; 14n - 29
To determine the difference;
We must first open the second parenthesis by multiplying through by its coefficient as follows;
5(−2.4n+4) = -12n +20.Afterwards; we have;
(2n−9)−(-12n +20)= 2n -9 + 12n -20= 14n - 29

For a given input value q, the function f outputs a value r to satisfy the following equation. 11q-4=3r-6, Write a formula for f(q) in terms of q
Final answer:
To find the formula for f(q), solve the equation 11q-4=3r-6 for r. The steps include adding 6 to both sides and then dividing by 3, resulting in f(q) = (11q + 2) / 3.
Explanation:
To write a formula for f(q) in terms of q, we need to solve the equation 11q - 4 = 3r - 6 for r, the output of the function f. First, we add 6 to both sides to isolate the terms with r on the right side of the equation:
11q - 4 + 6 = 3r - 6 + 6
11q + 2 = 3r
Next, we divide both sides by 3 to solve for r:
(11q + 2) / 3 = 3r / 3
(11q + 2) / 3 = r
Therefore, the formula for f(q) is:
f(q) = (11q + 2) / 3

what is 0.279 times 53
Final answer:
To calculate 0.279 times 53, multiply 279 by 53 and then place the decimal point three places from the right of the product, resulting in 14.787. If rounding to two decimal places, the answer is 14.79.
Explanation:
To find the product of 0.279 times 53, we can follow the usual multiplication process. We multiply as if there were no decimal places, and then we count the total number of decimal places in both numbers to place the decimal in the correct position in the final answer.
0.279 has three decimal places, and 53 has none. After you multiply 279 by 53, count three places from the right of the resulting number to place the decimal point. So, if 279 times 53 equals 14787, then 0.279 times 53 equals 14.787.
Applying the rules of rounding, if we wanted to round the result to two decimal places we would get 14.79 since the third decimal place is a 7 which rounds up the second decimal place from 8 to 9.
