Write and solve a word problem that can be modeled by addition of two negative numbers integers

777dan777 [17]

A word problem that can be modeled by addition of two negative numbers integers is given as followed.

Evans and Irvin are standing at the same spot. Evans took 7 steps backwards and another 7 steps backward, what is the current position of Evans relative to where Irvin is standing?

To solve the above, we note that Evans took 7 steps backwards and another 7 steps backward, thus his current position relative to Irvin is given by (-7) + (-7) = -7 - 7 = -14.

Therefore, Evans is 14 steps backwards relative to where Irvin is standing.

1. S = 10 mm V= S×S×S =___×___×___ =____ mm3

Minchanka [31]

Hi there!

»»————-　★　————-««

I believe your answer is:

$V=1000\text{mm}^3$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

I am assuming by the infomation given that the figure is a cube.

⸻⸻⸻⸻

$\boxed{\text{Finding the volume of the cube...}}\\\\S = 10mm; V= s^3\\--------------\\\rightarrow V = 10^3\\\\\rightarrow V = 10 * 10 * 10\\\\\rightarrow \boxed{V=1000\text{mm}^3}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
