If 4(r+2)-13=11, what is the value of r ?

Answer:

r=4

Step-by-step explanation:

First you multiply 4 by r which gives you 4r. Then you multiply 4 by 2 to give you 8.So it looks like this now

4r+8-13=11

Now you add thirteen to both sides and get

4r+8= 24

Then you subtract both sides by 8 to get 16

4r=16

Then you divide both sides by 4 to get 4

r=4

The value of r for equation 4(r+2)-13=11 is 4.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given equation is,

4(r+2)-13=11,

Add 13 in both the sides,

4(r+2)-13+13=11+13,

4(r+2) + 0 = 24

4(r+2) = 24

Divide by 4 both sides,

r+2 = 6

r= 4

The value of r is 4.

Read the excerpt from "Egyptian Tombs: A Grave Matter.”

From the twenty-fifth century BCE, pharaohs’ tombs were located inside grand pyramids. The pyramids served as giant grave markers; however, they also served as treasure markers for grave robbers. These wicked people would strip the tombs bare of all valuables. Then they would sell the stolen items for a large amount of money. Stealing from the dead was bad enough, but for the ancient Egyptians, the act also threatened the pharaoh’s afterlife.

Based on the details in the excerpt, what conclusion can be drawn about the pharaohs of ancient Egypt?

They went to great lengths to ensure that their tombs were prepared for the afterlife by placing valuables inside.
They liked the pyramid shape, so they used it as a tomb.
They thought that giant grave markers would protect them against grave robbers.
They placed more emphasis on their current lives than on their afterlives.
