Answer: As given, relationship between the number of hours a plumber works and the total work fee she charges is proportional.

The meaning of proportional is Ratio of number of hours a plumber works and the total work fee she charges is constant.

Using Unitary method

5 hours of work = $350

1 hours of work = $70

Let number of hours worked = x hours

Amount earned for x hours of work is represented by = $ y

For , x hours of work amount earned = 70 x (x=1,2,3...)

→y= 70 x

Sorry , I might be wrong : 35664

Step-by-step explanation:

So, first, we can find 33% of 53,200

That is 17,556

Then, we can subtract 17556 from 53,200

We get 35664

Answer:

3x - 2y = 12

Step-by-step explanation:

3x-2y=12 is the standard form of equation y=3/2x - 6

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The equation is y=3/2x - 6

y equal to three by two times of x minus six

y=3/2x - 6

LCM of 1 and 2 is 2

y=(3x-12)/2

Now apply cross multiplication

2y=3x-12

Two times of y equal to three times of x minus twelve

Now take 2y to RHS side

3x-2y-12=0

3x-2y=12

Hence 3x-2y=12 is the standard Form of equation y=3/2x - 6.

Answer:

2+2 is 4

Step-by-step explanation:

1 Remove parentheses.

-8(c-10)=−c+3

2 Regroup terms.

-8(c-10)=3−c

3 Expand.

-8c+80=3−c

4 Add 8c8c to both sides.

80=3−c+8c

5 Simplify 3-c+8c to 3+7c

80=33+7c

6 Subtract 33 from both sides.

80-3=7c

7 Simplify 80-3 to 77.

77=7c

8 Divide both sides by 7.

77/7 = c

9 Simplify 77/7 to 11.

11=c

10 Switch sides.

c=11

Sorry about my comment its all messed up, I thought you added a fraction like you did in an answer. Someone answered before me and i just copied mine and pasted it into a comment but it made it all weird. Happy holidays

Answer: m= -1/5

Step-by-step explanation:

Find the Slope (4, 2) and (9, 1)

Slope is equal to the change in y over the change in x, or rise over run.

              change in y

     m =    _________

              change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).        y₂ − y₁

     m =   _____

              x₂ − x₁

Substitute in the values of x and y into the equation to find the slope.

              1 − (2)

     m =   _____

              9 − (4)

Simplify the numerator.

                −1

     m =   _____

              9 − (4)

Simplify the denominator.

                −1

     m =   _____

                 5

Move the negative in front of the fraction.

                −1

     m =   _____

               − 5

Answer:

The slope of the line is [tex]\displaystyle -\frac{1}{5}[/tex].

Step-by-step explanation:

We are given two coordinate points:

We are asked to find the slope of the line.

We can use the rise-over-run formula to solve for the slope of the line.

[tex]\displaystyle \text{slope} = \frac{\text{rise}}{\text{run}}\\\\\text{slope} = \frac{y_2-y_1}{x_2-x_1}[/tex]

However, we firstly need to name our coordinate points.

In math, we can label our coordinates using the following label system:

[tex](x_1, y_1), (x_2, y_2)[/tex]

Therefore, we can also label our coordinates as such:

Now, we can supply these values into the formula and solve for our slope, or a better known variable, m.

[tex]\displaystyle m = \frac{1 - 2}{9 - 4}\\\\m = \frac{-1}{5}\\\\m = -\frac{1}{5}[/tex]

Therefore, our slope is [tex]\displaystyle -\frac{1}{5}[/tex].

6%

Step-by-step explanation:

Estimated distance = 80 miles

Actual distance covered = 75.5 miles

We need to find the percent error of the cyclist's estimate. Its formula is given by :

[tex]\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100[/tex]

Put all the values,

[tex]\%=\dfrac{80-75.5}{75.5}\times 100\\\\=5.96\%[/tex]

Answer: Choice C

x+y = 28

3x+4y = 100

===================================================

Explanation:

x and y are placeholders for nonnegative whole numbers.

Specifically,

x = number of three point questions

y = number of four point questions

Since we have 28 questions total, this must mean x+y = 28. That forms the first equation in our system of equations.

------------

Now let's form the second equation:

x = number of three point questions

3x = points we get from all the three point questions

y = number of four point questions

4y = points we get from all the four point questions

3x+4y = all points possible

3x+4y = 100  is the second equation

------------

So we have this system

[tex]\begin{cases}x+y = 28\\3x+4y = 100\end{cases}[/tex]

which fits the conditions in the instructions.
