4. Find the value of n that makes this equation true. (Use
andreyandreev [35.5K]

Answer:

n=4

Step-by-step explanation:

We start off with 3.2n + 13.3 = 26.1.

We need to get n by itself.

Subtract 13.3 from both sides.

3.2n+13.3-13.3=26.1-13.3

26.1-13.3=12.8

We end up with: 3.2n=12.8

Divide 3.2 on both sides to get n by itself.

\frac{3.2n}{3.2} =\frac{12.8}{3.2}\\ n=4

A flower pot has a diameter of 6 feet. What is the area of the flower pot, to the nearest whole number?
Elodia [21]

Answer:

28 ft²

Step-by-step explanation:

The area of a circle is \pi r^2, where r = radius. To find the radius, we split the diameter in half.

  • 6/2 = 3
  • Thus, the radius is 3.

Now, let's find the area of the circle and approximate pi to 3.14.

  • 3.14*3^2
  • 3.14*9
  • 28.26
  • 28.26 ≈ 28 ft²

Therefore, the answer is 28 ft².

What is negative 7 minus negative 2
zalisa [80]

Answer:

-5

Step-by-step explanation:

-7 - (-2)

-7 + 2

Example: If you owe someone $7, and you give them $2, how much do you still owe? You are owing him $7 so it's a negative and you give him $2 which is a negative as well since you are giving it to him. So, to answer how much do you still owe, you would add $2  to the $7 you owed, so now, you owe him $5, which is a negative since you OWE him.

Hope this helps:)
