Andrea does not understand why if x is a solution to the equation 3-x=4 then x is also a solution to the equation 12=9-3x. Write a convincing explanation as to why this is true

Answers

Answer 1

Answer:

Both equations are same

Step-by-step explanation:

The reason why this is true is not far fetched

looking at the first equation, we have;

3-x = 4

we can also factorize the second equation to look this way

By this, we shall be having

3(4) = 3(3-x)

By the time we take out the 3 from both sides, we will have the initial equation

So what we are saying is that both equations are the same

A construction crew will build a new railroad track which passes through the point (8,5) and is parallel to the one
modeled by the line. What equation models the path of the new track?

Answers

Answer:

y = [tex]-\frac{2}{9}x+\frac{61}{9}[/tex]

Step-by-step explanation:

Let the equation of the new railroad track passing through the point [tex](x_1,y_1)[/tex] and slope = m₁ is,

[tex]y-y_1=m_1(x-x_1)[/tex]

Slope of the given line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of the line passing through (-3, 1) and (6, -1) will be,

m₂ = [tex]\frac{1+1}{-3-6}[/tex]

m₂ = [tex]-\frac{2}{9}[/tex]

Since, railroad track and the given line are parallel,

m₁ = m₂ = [tex]-\frac{2}{9}[/tex]

Therefore, equation of the railroad track passing through (8, 5) and slope = [tex]-\frac{2}{9}[/tex] will be,

y - 5 = [tex]-\frac{2}{9}(x-8)[/tex]

y = [tex]-\frac{2}{9}x+\frac{16}{9}+5[/tex]

y = [tex]-\frac{2}{9}x+\frac{61}{9}[/tex]

5.Tammy rents an apartment close to her school campus. She pays $600 per month. r is the amount spent on rent and m is the number of months she stays in the apartment. Write the two equations that represent this proportional relationship.

Answers

Answer:

The two equations are

r = 600m

and

r/600 = m

Step-by-step explanation:

Here, we want to write equations

The equation is;

r(m) = 600m

where r is the amount spent and m is the number of months

r = 600m

and r/600 = m

Answers

Answer:

± 5.919

Step-by-step explanation:

Margin of Error formula = z × standard deviation/√n

Z score for 99% confidence interval = 2.58

n = 19

Standard deviation = 10

Margin of Error = 2.58 × 10/√19

Answers

Answer:

Step-by-step explanation:

Sasha can paint 400 square feet using 1 gallon of paint

If she needs to paint 4,704 square feet, then she will need to purchase 4,704 / 400 = 11.76 gallons of paint. Since she can only purchase paint in whole gallons, she will need to purchase 12 gallons of paint (we have to round up).

Which expression has the sum of twenty six twentieths? (4 points) Selected:a. two fifths plus four tenthsThis answer is incorrect. b. four fifths plus two fourths c. one half plus three tenths d. three fourths plus two fifths
a is wrong

Answers

Answer: b. four fifths plus two fourths

Step-by-step explanation: Change the fractions to their equivalents in 20ths-- like finding the common denominator.

Divide the original denominator into 20, then multiply the result by the original numerator to get the new numerator.

4/5  20/5 = 4    4×4 = 16   so 4/5 is equivalent to 16/20

2/4   20/4 = 5    5×2 = 10   so  2/4 is equivalent to 10/20  

Add:    16/20 + 10/20 = 26/20

help me find p.....​

Answers

Answer: p = 120 degrees

Step-by-step explanation:

Figure a shows a pentagon. The sum of interior angles in a pentagon is equal to 540 degrees.

1. Subtract the known numerical angle

540 - 60 = 480

All of the remaining angles (represented by the variable p) are equal to one another. Therefore, we can use the expression 4p = 480 to find the value of p.

2. Evaluate the equation to find the value of p.

4p = 480

p = 120
