for this case we must write a proportion that shows the earnings obtained from Mrs. Miller for the sale of the house.

By making a rule of three we have:

179000 ------------> 100%

x -----------------------> 6%

Where "x" represents the gains obtained.

So:

x = \frac {6 * 179000} {100}

Writing the proportion:

\frac {x} {179000} = \frac {6} {100}

The earns were:

x = 10740

ANswer:

\frac {x} {179000} = \frac {6} {100}\\x = 10740

Answer:

$10,740

Step-by-step explanation:

You know that Mrs. Miller sells a house for $179,000. Then the cost of the house will be the 100%.

Knowing that she earns 6% of comission, you can set up the following proportion (Let be "x" the amount of money she earns), then:

\frac{\$179,000}{100}=\frac{x}{6}

Now you need to solve for "x". Therefore, you get:

 (6)(\frac{\$179,000}{100})=x

 x=\$10,740

I need help with this finding x problem please show work
zubka84 [21]

Answer:

The model represents the equation

-3x + 6 = 4x -8

Start by subtracting 6 from both sides.

-3x + 6 (-6) = 4x - 8 (-6)

-3x = 4x - 14

Subtract 4x from both sides

-3x - 4x = 4x - 4x - 14

-7x = -14

x = -14/-7

x = 2

What’s the awnser(can someone do these for me i’m begging you my parents are gonna kill me)

Answer:

-3/2

(2x-14)/3

(-2,-6)

Step-by-step explanation:

I solved the first one for you already ( -3/2)

To make a line perpindicular to another line they need to intersect at a 90 degree angle. To do this the slope of the lines have to be the negative  reciprical (take the fraction, flip it, and apply a negative sign to it)

If you do this to -3/2 you get 2/3

If we follow our y=mx+b equation from before we (so far) have

2/3x+b=y

which means that we just need to solve for b

We also know that it crosses the point (7,0) which means that if we plug in 7 for x and 0 for y we can solve for b

we have

(2/3)*7+b=0

Solve for B

14/3+b=0

b= -14/3

Which means our equation looks like this

(2x-14)/3

our two equations look like this

(-3/2)x-9

(2x-14)/3

We need to find where their coordinates are the same (where they intersect)

We can do this by setting them equal to each other and then solving for x

we have

(-3/2)x-9=(2x-14)/3

solve for x

-4.5x-27=2x-14

-13= 6.5x

x= -2

Now that we know what x equals we can plug this into any of our two beginning equations

(-3/2)*-2-9=y

3-9=y

-6=y

Which means our coordinates are (-2,-6)
