Just draw a rectangle, cut it into 3 horizontal lines, and cut it into 4 vertical lines.
This one’s pretty easy because it’s a square meaning the corners will always be 90 degrees so if a line splits the 90 it becomes half which is 45. And the reason AEB is 90 is because it’s two top corners are 45 degrees so the last angle must make the whole triangle equal 180 degrees.
DBC=45
AEB=90
0.50c, as it's $0.50 per cup and c represents the number of cups sold. When you have a variable (letter like in this case, which is c) you always multiply.
And for 1b you're going to be doing $127.50 divided by $0.50
Let me know if this makes sense
Answer:
-1
Step-by-step explanation:
-2/3 - 1/3
Since the denominators are the same, we can combine the numerators
-3/3
Simplify

Answer:
4th option
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = 
with (x₁, y₁ ) = (2, 12) and (x₂, y₂ ) = (6, 6) ← 2 points on the line
m = 
= 
= - 
the line crosses the y- axis at (0, 15 ) ⇒ c = 15
y = - x + 15 ← approximate equation of line of best fit
