Hello!

\large\boxed{c = 2}

8c - 3c + 3 = 13

Begin by combining like terms:

5c + 3 = 13

Subtract 3 from both sides:

5c + 3 - 3 = 13 - 3

5c = 10

Divide both sides by 5:

5c/5 = 10/5

c = 2.

Ok please help meeeeeeeeeeeeeeeee

Answer:

Step-by-step explanation:

Volume of a cone is given by the formula,

V = \frac{1}{3}\pi r^{2}h

Here, r = Radius of the circular base of the cone

h = Height

By substituting values from the question,

V = \frac{1}{3}\times \pi (\frac{6}{2})^2(3)

V = 9π

V = 28.27 m³ [Nearest hundred]

If we have to round the answer to the nearest tenth, answer will be,

Volume = 28.3 m³

If we have have to round the answer to the whole number then the answer will be,

Volume = 28 m³

I need to solve for X btw they are same side interior ( supplementary angles )​
Sidana [21]

Answer:

x = 17.2

Step-by-step explanation:

since they are supplementary, when you add then together they equal 180

4x + 8 + 6x = 180

Combine like terms

10x + 8 = 180

subtract 8 from both sides

10x = 172

divide each side by 10

x = 17.2

hope this helps :)

PLS HELP MEEEEE! THIS IS DUE TODAY!

Answer: The road as metaphor. One great challenge in writing about roads, Ted Conover explains in the epilogue of his new road-themed nonfiction release The Routes of Man, is to avoid inadvertent use of the casual road metaphor. “So essential a part of the human endeavor are roads,” he writes, “that road- and driving-related metaphors permeate our language.
