Answer:

$\pi r2$ or $\pi d$

Step-by-step explanation:

To find the circumference, you must first find either the diameter or the radius.

To find the diameter, you can multiply the radius twice.

To find the radius, you can divide the diameter by 2.

Once you have the diameter, you then multiply it by pi, also known as 3.14.

Once you have the radius, you them multiply it by pi, also known as 3.14, and then multiply your product by 2.

4 tomatoes and 8 avocados cost $10. Six tomatoes and 14 avocados cost $17. How much does a single avocado and a single tomato co

Nataly_w [17]

Answer:

One avocado costs $1 and one tomato costs $0.50

Step-by-step explanation:

Set up a system of equations where t is the number of tomatoes and a is the number of avocados:

4t + 8a = 10

6t + 14a = 17

Solve by elimination by multiplying the top equation by 3 and the bottom equation by -2:

12t + 24a = 30

-12t - 28a = -34

Add them together and solve for a:

-4a = -4

a = 1

Plug in 1 as a into one of the equations and solve for t:

4t + 8a = 10

4t + 8(1) = 10

4t + 8 = 10

4t = 2

t = 0.5

So, one avocado costs $1 and one tomato costs $0.50

If they have -8 points and +6 points, that'd leave them with a total of -2 points.
So the answer is -2.
