Jane earns a 5.5% commission on the selling price of each home she sells. She earned $9,020 in commission on the sale of a home.
ratelena [41]

Answer:

"$164000" is the appropriate answer.

Step-by-step explanation:

Let the selling price be "s".

As per the question,

If Jane take 5.5% of selling price i.e.,

= 0.055\times s

Given commission,

= $9,020

then,

The selling price will be:

⇒ 0.055\times s=9020

                s=\frac{9020}{0.055}

                   =164000 ($)

Which of the following represents 3x-5y+10=0 written in slope-intercept form?
taurus [48]

For this case we have that by definition, the equation of a line in the slope-intercept form is given by:

y = mx + b

Where:

m: Is the slope

b: Is the cut-off point with the y axis

We have the following equation:

3x-5y + 10 = 0

We manipulate algebraically:

We subtract 10 from both sides of the equation:

3x-5y = -10

We subtract 3x from both sides of the equation:

-5y = -3x-10

We multiply by -1 on both sides of the equation:

5y = 3x + 10

We divide between 5 on both sides of the equation:

y = \frac {3} {5} x + \frac {10} {5}\\y = \frac {3} {5} x + 2

Thus, the equation in the slope-intercept form is y = \frac {3} {5} x + 2

Answer:

y = \frac {3} {5} x + 2

-4= 7x-(-1) / -8<br><br> Solve for x <br><br> (Solving multi step equations)
Evgen [1.6K]
Multiply both sides by -8.
Then add the one to both side to cancel it out and get 7x by itself
Then divide the whole thing by 7. So it’ll look like this: 32+1=7x and then add the one then divide by 7
