The equation shows that the pastries that must be sold at $3.55 each in order to make a profit is 23.
<h3>How to calculate the expression?</h3>
Let the number of units be represented by x.
Based on the information given, the equation will be:
75 + (0.15 × x) = 3.55 × x
75 + 0.15x = 3.55x
3.55x - 0.15x = 75
3.40x = 75
x = 75/3.40
x = 23
Therefore, the number is 23.

I am getting 7 as the value of b. I do not believe 4 is a correct answer!
Here's why:
General equation of a circle in the xy plane

with
being the x,y coordinates of the center.
The center point can be determined from the two endpoints of the diameter because the line segment is horizontal, so we just find the center of the x coordinates of the two points:

and the radius r = diameter/2 = 8-(-2)/2 = 5
so we have

Given a point on the circle (0,b) with b>0:

Answer:
All real numbers except x cannot equal 10.
Step-by-step explanation: the denominator can not equal to zero that is undefined.
Given parameters:
Actual length = 260m
Drawing length = 286mm
Unknown:
Scale used = ?
Solution:
A scale compares drawing length to ground distance;
To find the scale,
Express the two quantities in the same unit;
actual length = 260 x 10⁻³m = 0.26mm
Now;
drawing length : actual length
286mm : 260 x 10⁻³mm
divide by 286;
1mm on drawing : 9 x 10⁻⁴mm on map
or;
1mm on drawing is 0.9m on ground
"Reflexive Property" is the property shown as a = a
