What is the solution to 1/3 (9x+3) = 3x+1
Please show work so I can compare my answer :)

Answers

Answer 1
1/3 (9x+3) = 3x+1
Multiply both sides of the equation by 3.
9x+3=9x+3

The statement is true for any value of , because both sides are identical
Answer 2
So, you have to distribute.

1/3 • 9 = 3x
1/3 • 3 = 1
3x+1, since 1 is a positive number, you don’t subtract. Looks like you did the work right.

What are parallel lines?

For a pair of lines, the perpendicular distance is equal at every point, then the pair of lines are called parallel lines.

The given information are:

1. Angle 2 is congruent to angle 4.

Angle 2 and Angle 4 are opposite angles. They are always equal.

This information does not prove that 'u' parallel to 'v'.

2. Angle 4 is congruent to angle 8.

Angle 4 and Angle 8 are corresponding angles.

This information proves that 'u' parallel to 'v'.

Angle 6 + angle 7 = 180 degrees.

The sum of the angle 6 and angle 7 are always 180 degrees.

This information does not prove that 'u' parallel to 'v'.

Step-by-step explanation:

Light travels from the sun at 1.12 x 107 miles per minute. The planet, Mars, is approximately 1.42 x 108 miles away from the sun.
What is the approximate amount of time, in minutes, for light to travel from the Sun to Mars? Write your answer in scientific notation rounded to the nearest hundredth.

Answers

Answer:

Time = 1.27 x 10^1 minutes

Step-by-step explanation:

To calculate the approximate amount of time it takes for light to travel from the Sun to Mars, we can divide the distance between them by the speed of light.

Given:

Speed of light = 1.12 x 10^7 miles per minute

Distance between the Sun and Mars = 1.42 x 10^8 miles

Time = Distance / Speed

Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)

Time = (1.42 / 1.12) x 10^(8 - 7) minutes

Time = 1.27 x 10^1 minutes

Rounded to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.70 minutes in scientific notation.

To calculate the approximate amount of time for light to travel from the Sun to Mars, we can use the formula:

Time = Distance / Speed

Given:
Speed of light = 1.12 x 10^7 miles per minute
Distance from the Sun to Mars = 1.42 x 10^8 miles

Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)

To simplify the calculation, we can divide the numerical values and subtract the exponents:

Time = 1.42 / 1.12 x 10^(8 - 7) minutes

Time = 1.27 x 10^1 minutes

Rounding to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.7 minutes in scientific notation.

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)

Answers

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Answer:

A = 324m²

Step-by-step explanation:

Formula for finding the surface area of a rectangular prism:

2(wl + hl + hw)

First, let's find out which one of the measurements is the height, length, or width.

6m = length

16m = width

3m = height

Next, we calculate the surface area. We have to do the formula one by one too.

2(wl + hl + hw)

2(16x6 + 3x6 + 3x16)

16 x 6 = 96

3 x 6 = 18

3 x 16 = 48

Now, we add those together.

96 + 18 + 48 = 162

Lastly, multiply by 2.

162 x 2 = 324

Therefore, A = 324m²

Identifying the values a, b, and c is the first step in using the Quadratic Formula to find solution(s) to a quadratic equation.

What are the values a, b, and c in the following quadratic equation?

−6x2 − 8x + 12 = 0

a = −6, b = −8, c = 12
a = 6, b = 8, c = 12
a = 8, b = 12, c = 0
a = −8, b = 12, c = 0

Answers

Answer: A!

Step-by-step explanation: The quadratic formula is ax2+bx+c, so you just plug in and see which ones go with the equation, a=-6 (-6x2) b=-8 (+-8 or -8) and c=12 (+12) Hope this helps

The perimeter of a rectangle is equal to twice the sum of its length and its width. One rectangle has a length of 13 1/8 inches and a perimeter of 42 1/2 inches. Write an equation that can be used to find the width of the rectangle. Explain how you found your answer.

Answers

Answer:

8 1/8 inches

Step-by-step explanation:

P = 2 ( l+w)

l = 13 1/8

P = 42 1/2

Substitute the two values into the equation

42 1/2 = 2 ( 13 1/8 + w)

Change the mixed numbers to improper fractions

42 1/2 = ( 2 *42+1)/2 = 85/2

13 1/8 = ( 8*13+1) /8 =105/8

85/2= 2 (105/8+ w)

Divide each side by 2

85/2 *1/2= 2/2 (105/8+ w)

85/4 = (105/8+ w)

Subtract 105/8 from each side

85/4 -105/8 = (105/8-105/8+ w)

Get a common denominator

170/8 -105/8 = w

65/8 = w

Change back to a mixed number

64/8 + 1/8 = w

8 1/8
