In this question, each package has 8 notecards.
one notecard costs $8
2 notecards cost $16
3 notecards cost $24
if n - number of packages
d - selling price in dollars
We can see that with each additional notecard bought the cost increases by $8
therefore there's a proportional relationship between n and d
As n increases, d increases by the same amount.
if we put it in an equation,
d = 8*n
n - 1 package and d is 8
if n - 2
d = 8*2
d = 16
Therefore we can use the following equation;
d=8n
Answer:

Step-by-step explanation:
Assuming this pizza is a circle, we can use this formula for area:

1. Find Radius
We are given the diameter: 12 inches, but the formula uses radius.
The radius is half the diameter, or:



2. Calculate Area
Substitute the radius (6 inches) in for r. The question also asks us to use 3.14 for pi.

Solve the exponent.
- (6 in)²= 6 in* 6 in= 36 in²

Multiply.

3. Round
The question asks us to round to the nearest tenth.
The 4 in the hundredth place tells us to leave the 0 in the tenth place.

The area of the pizza is about 113.0 square inches.
Answer:
the answer is 0
Step-by-step explanation:
a negative plus a positive is a positive
Answer:
961/40 - 204/40 + 60/40 = 817/40 or 20 17/40
Step-by-step explanation:
Make the mixed numbers into fractions. Then make them have equal denominators. It's easier to stick with 40 as the denominator.
Step-by-step explanation:
f(x) is another way of saying y.
360-9x=y
You would then graph the equations and list the ordered pairs that line crosses on the x-axis and the y-axis.3
