F = 1/2(r + 6.5)
2f = r + 6.5
r = 2f - 6.5

Answer:37 paintings of $50 and 15 paintings of $75</h2>
Step-by-step explanation:
Let be the number of paintings Ella sells for $.
Let be the number of paintings Ella sells for $.
Profit made through $ paintings is
Profit made through $ paintings is
So,total profit is given by
It is given that total profit is $
So, ..(i)
Given that the total number of prints is
So, ..(ii)
using (i) and (ii),
Answer:
Step-by-step explanation:
Change the 2/3 to 4/6
Now the ratio becomes 3:4:6
So the number of each is
3x + 4x + 6x = 520
13x = 520
x = 40
Red = 3*40 = 120
Yellow = 4*40 = 160
Blue = 6 * 40 = 240
Total = 520

Hi there!
Point-slope form: where <em>m</em> is the slope of the line and is a given point
Given that the slope is -3/4, we can plug it into as <em>m</em>:
We can also plug in the given point (1,2):
Slope-intercept form: where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when the line crosses the y-axis)
To write the equation in slope-intercept form, isolate <em>y</em>:
I hope this helps!
