(02.01 LC) Solve: negative 1 over 2 x + 3 = −x + 7 (5 points) 1 over 2 8 −8 2
Answer:
2 8 -8 2
Step-by-step explanation:
The correct answer is [tex]-\frac{1}{2}x + 3 = -x + 7$ is $x = 8[/tex].
To solve the equation [tex]-\frac{1}{2}x + 3 = -x + 7[/tex], we can follow these steps:
Step 1: Combine like terms on both sides of the equation.
[tex]-\frac{1}{2}x + 3 = -x + 7[/tex]
[tex]\frac{1}{2}x - 3 = x - 7[/tex]
Step 2: Subtract [tex]x[/tex] from both sides to isolate the terms with [tex]x[/tex].
[tex]\frac{1}{2}x - 3 - x = -7[/tex]
[tex]-\frac{1}{2}x - 3 = -7[/tex]
Step 3: Add 3 to both sides to isolate the term with [tex]x[/tex].
[tex]-\frac{1}{2}x = -4[/tex]
Step 4: Multiply both sides by [tex]-2[/tex] to solve for[tex]x[/tex].
[tex]-2 \left(-\frac{1}{2}x\right) = -2(-4)[/tex]
[tex]x = 8[/tex]
Therefore, the solution to the equation [tex]-\frac{1}{2}x + 3 = -x + 7$ is $x = 8[/tex]

Sandra got a 3/27 balloon mortgage and her initial payments were $945. She decided to refinance her balloon payment with a 30-year mortgage and her new payments were $937. What is the total financed cost she paid for her house?
Sandra got a 3/27 balloon mortgage and her initial payments were $945.
This means Sandra paid $945 per month for 3 years. Total payment made in 3 years = 945*3*12 = $34,020
Later, she decided to refinance her balloon payment with a 30-year mortgage. Her new payments were $937.
Payment made under mortgage = 937 * 30 * 12 = $337,320
The total financed cost she paid for her house = $34020 + $ 337320 = $371340
Hope this helps..!!
Thank you :)

Nelly owns farm land that has an area of 4.2 × 102 acres. Each year, the farm produces 6.72 × 104 bushels of corn. What is the average amount of corn produced per acre represented in scientific notation?
A) 2.82 × 107 bushels per acre
B) 1.6 × 102 bushels per acre
C) 1.6 × 103 bushels per acre
D) 2.82 × 106 bushels per acre
E) 1.6 × 101 bushels per acre
The average amount of corn produced per acre represented in scientific notation can be found using the below formula:
[tex] The \;average\; amount\; of\; corn\; per\; acre=\frac{Bushels \; of\; corn\; produced\; in\; farm}{Area\; of\; farm\; in\; acres} [/tex]
We are given:
[tex] Area \; of\; FARM\; land= 4.2 \times 10^2 \; acres\\ \\ Amount \; of\; corn\; produced=6.72\; \times \; 10^4 \; bushels [/tex]
Substituting the above information in the formula, we get...
[tex] The \; Average\; amount\; of\; corn=\frac{6.72 \times 10^4}{4.2 \times 10^2} \\ \\ \frac{6.72}{4.2} \times \frac{10^4}{10^2}\; =\; 1.6 \times 10^{4-2}\; =\; 1.6 \times 10^2\\ \\ [/tex]
Conclusion:
[tex] The \; Average \; amount\; of \; corn \; is\; 1.6 \times 10^2 \; Bushes\; per\; corn [/tex]
The average amount of corn produced per acre represented in scientific notation is option B)[tex] 1.6 \times 10^2 [/tex]bushels per acre
Le answer is B 1.6 × 102 bushels per acre

which cream cheese has the lowest price per ounce?
A: $2.59 for 6oz
B: $2.89 for 8 oz
C: $4.29 for 12 oz
D: $5.29 for 14 oz
Answer:the correct answer is $4.29 for 12 oz.
Step-by-step explanation:
The cream cheese which has the lowest price per ounce is the one which is $4.29 for 12 oz. Thus, the correct option is C.
What is Ounce?The ounce is any of the several different units of mass, weight or volume and it is derived almost unchanged from the uncia, unit of measurement.
The ounce is 1/16 avoirdupois pound. This is the United States customary and British imperial ounce. Ounce is primarily used in the United States to measure packaged foods and food portions, areal density of fabric and paper, boxing gloves, and so on, but it is sometimes also used elsewhere in the Anglosphere.
The price for per ounce of different cream cheese will be:
a. 2.59/ 6 = 0.431
b. 2.89/ 8 = 0.361
c. 4.29/ 12 = 0.357
d. 5.29/ 14 = 0.377
Therefore, the cream cheese which has the lowest price per ounce is the one which costs $4.29 for 12 oz.
Therefore, the correct option is C.

Which of the following situations models a geometric sequence? Select all that apply.
Answer:
Options 1, 3, 4.
Step-by-step explanation:
We will check each and every option given here.
1) Amount of cell phone users increases by 33% every year.
Its a geometric sequence because the number of users are increasing exponentially every year.
2) Amount of cakes in bake sale increases by 3 each year the fundraiser is held.
amount of cakes is increasing with a common difference of 3 so it's an arithmetic sequence.
3).Uranium loses half of its weight every 415 years.
Exponential decay in every 415 years. So geometric sequence with a common ratio of 1/2.
4).A family of rabbits doubles in size every 3 months.
Exponential series again so geometric sequence with a common ratio of 2.
5).Car drives at a constant speed of 58 mph.
Its a linear function representing an arithmetic sequence with a common difference of 58 mph.
6). Number of students increases by 122 every year.
An arithmetic sequence with a common difference of 122.

What is the area of a sector with a central angle of 5pi/7 radians and a diameter of 5.6 in.? Use 3.14 for pi and round your final answer to the nearest hundredth.
Which example best represents balanced forces
The forces are equal and opposite, the book remains at rest, representing a state of balanced forces.
Balanced forces occur when the net force acting on an object is zero, meaning that the forces are equal in magnitude and opposite in direction. As a result, the object remains in a state of equilibrium and does not accelerate.
One example that best represents balanced forces is:
A book resting on a table.
When a book is placed on a table, it doesn't move because the force of gravity pulling it down (its weight) is balanced by the normal force exerted by the table, pushing the book upward.

Which expression is equivalent to(3m^-2 n)^-3/6mn^-2? Assume
To simplify the expression (3m⁻² n)⁻³/6mn⁻², follow the steps: apply the negative exponent rule, simplify by multiplying the exponents, and rearrange and combine like terms if necessary.
Explanation:To simplify the expression (3m-2 n)-3/6mn-2 , let's break it down step by step:
Step 1: Apply the negative exponent rule. To do this, we can move any term with a negative exponent from the numerator to the denominator or vice versa. In this case, the term m-2 can be written as 1/m2.
Step 2: Simplify the expression by multiplying the exponents. The exponents in the expression can be added since they have the same base (m).
Step 3: Simplify further by rearranging and combining like terms if necessary.
Putting it all together, the expression is equivalent to (1/3m4n6)1/6mn-2.
