If 9 pizzas cost $67.50 that means that 1 pizza costs 67.50/9 = $7.5
Answer A is incorrect because of false prize of pizza.
B isn't correct because 1 pizza cost $7,5 and not 7,5 pizzas cost $1
C isn't answer because of both reasons from answer A and answer B
D is the answer because it says that you need to pay $7.5 per pizza.
Answer:
f(x) = 3x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)
m = 
= 3 , then
y = 3x ← is the equation of the graphed line
The equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t
<h3>Equation</h3>
There are three basic types of equation in mathematics. Namely:
- Linear equations
- Quadratic equations
- Simultaneous equations
- Monthly fee = $50
- One-time joining fee = $150
- Total cost = C
- Number of months = t
C = 150 + 50t
Therefore, the equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t

Answer:
126mm
Step-by-step explanation:
To find the diameter of the circle = circumference divided by pi = 56.52/3.14=18mm.
There are 4 circles = 18mmx4=72mm
Add on the 3x strips = 72+(18x3) = 126mm.
Hope this helps
