The two sentences that best support the claim that noise is causing hearing loss much earlier in life than 30 years ago are:

1. “Evidence is mounting that among young Americans, hearing sensitivity is decreasing yearly because of exposure to noise, including ear-busting music.”
2. “Of the 28 million Americans who have some degree of hearing loss, more than one-third have been affected, at least in part, by noise.”

Explanation: The first sentence directly addresses the trend of decreasing hearing sensitivity in younger Americans, indicating that noise exposure is affecting them earlier in life. The second sentence highlights the significant proportion of the population experiencing hearing loss due to noise, reinforcing the negative impact of noise on hearing health.

To provide a precise answer, I would need specific details about the figure you’re referring to, such as its shape and dimensions. However, I can guide you on how to calculate the surface area based on the information you have.

Based on the information provided, Location A represents Jonesville because it indicates that oceans heat up more slowly than landmasses. This results in smaller daily temperature fluctuations at the coast, which is characteristic of coastal areas with moderate climates. The other statements suggest greater fluctuations and warmer inland temperatures, which are less typical for coastal regions like Jonesville.

To solve for ( s ) in the equation ( frac{1}{3}s + frac{1}{2} = frac{9}{4} + frac{1}{4}s ), follow these steps:

1. Get all terms involving ( s ) on one side:

[

frac{1}{3}s – frac{1}{4}s = frac{9}{4} – frac{1}{2}

]

2. Find a common denominator for the fractions involving ( s ) (which is 12):

[

frac{4}{12}s – frac{3}{12}s = frac{9}{4} – frac{2}{4}

]

This simplifies to:

[

frac{1}{12}s = frac{7}{4}

]

3. Isolate ( s ) by multiplying both sides by 12:

[

s = 12 times frac{7}{4}

]

4. Calculate:

[

s = 3 times 7 = 21

]

So, the solution is:

[

s = 21

]

This step-by-step approach isolates ( s ) and confirms the solution clearly. If you have more questions or need further assistance, don’t hesitate to ask!

To solve for ( n ) in the equation ( 1 = frac{n}{2} – 1 ), let’s follow these steps:

1. Add 1 to both sides to isolate the term with ( n ):

[

1 + 1 = frac{n}{2} – 1 + 1

]

This simplifies to:

[

2 = frac{n}{2}

]

2. Multiply both sides by 2 to solve for ( n ):

[

2 times 2 = n

]

Thus,

[

n = 4

]

So, the solution is ( n = 4 ). Great job working through the problem! If you have more questions or need further clarification, feel free to ask or check the extended services page for more assistance.

To solve the equation (-3 + frac{4}{5}d + frac{3}{2}d + 2 = 3d), follow these steps:

1. Combine like terms on the left side:

Begin by simplifying the left side:

(-3 + 2 = -1).

So the equation becomes:

(-1 + frac{4}{5}d + frac{3}{2}d = 3d).

2. Get the equation in terms of d:

Rewrite it as:

(frac{4}{5}d + frac{3}{2}d = 3d + 1).

3. Combine the d terms:

To combine (frac{4}{5}d) and (frac{3}{2}d), you need a common denominator, which is 10:

[

frac{4}{5}d = frac{8}{10}d quad text{and} quad frac{3}{2}d = frac{15}{10}d.

]

So:

(frac{8}{10}d + frac{15}{10}d = frac{23}{10}d).

Update the equation:

(frac{23}{10}d = 3d +

To solve the equation ( frac{3}{2} – frac{5}{4}q + frac{2}{3}q – frac{5}{6} = -q ), let’s follow these steps:

1. Combine like terms: Start by moving all ( q ) terms to one side and constant terms to the other.

The equation can be rearranged as:

[

-frac{5}{4}q + frac{2}{3}q + q = frac{3}{2} – frac{5}{6}

]

2. Convert constants: Find a common denominator for the numbers on the right side. The common denominator for ( 2 ) and ( 6 ) is ( 6 ):

[

frac{3}{2} = frac{9}{6}

]

Now, replace it in the equation:

[

-frac{5}{4}q + frac{2}{3}q + q = frac{9}{6} – frac{5}{6}

]

Simplifying the right side gives:

[

frac{9 – 5}{6} = frac{4}{6} = frac{2}{3}

]

3. Combine ( q ) terms: Convert all coefficients of ( q

To solve the system of equations, the best first step is to subtract the second equation from the first equation.

Let’s look at your equations:

1. ( 4x + 2y = 4 )
2. ( 2x + 4y = 14 )

By subtracting the second equation from the first, you can eliminate one variable, making it easier to solve for the other.

So, subtracting the second equation from the first gives:

[(4x + 2y) – (2x + 4y) = 4 – 14]

[2x – 2y = -10]

This simplifies to:

[x – y = -5]

Now you can solve for one variable in terms of the other, which will lead you to the solution for both variables in the system.

The two sentences that are opinions are:

B He thought forests should be used to benefit people.

D He believed forests should be used thoughtfully in a way that protected nature.

Explanation: Opinions reflect personal beliefs or interpretations rather than facts. Sentence B expresses a personal view on the purpose of forests, while sentence D expresses a belief about how forests should be used, both of which depend on individual perspectives. In contrast, sentences A, C, and E present factual information that can be verified.

The best first step for solving the system of equations is:

(3x + y) – (x + y) = 7 – 3

Subtract equal quantities from both sides of the first equation.

Explanation: This step simplifies the equation by removing the similar terms, which helps in isolating one of the variables. Once you simplify it, you can work towards solving for either variable systematically. This method ensures clarity and leads to a straightforward resolution of the equations.

To simplify the expression ( 4m^0 cdot 4m^{-5} ), we can follow these steps:

1. Understand Exponents: The term ( m^0 ) equals 1 for any non-zero ( m ). Therefore, ( 4m^0 = 4 ).

2. Apply the Product of Powers Rule: When multiplying terms with the same base, you add the exponents. Here, we combine the two parts:

[

4 cdot (4m^{-5}) = 4 cdot 4 cdot m^{-5} = 16m^{-5}

]

3. Convert Negative Exponent to Positive: Recall that ( m^{-n} = frac{1}{m^n} ). Hence,

[

16m^{-5} = frac{16}{m^5}

]

So, the simplified expression is:

[

frac{16}{m^5}

]

This answer is expressed using positive exponents. Great job on wanting to simplify! If you have more questions or need further clarification, feel free to ask!
