Answer:
20 comic books
Step-by-step explanation:
Let us first <u>set up a variable</u>, x, for the number of books that Zoe has. If Jared has 12 more comics than Zoe, he would have x+12 books.
Given that Zoe and Jared have a total of 28 comic books, let us write an <u>equation</u> and solve for x:
Now that we have a <u>simplified</u> version of the equation, let us solve for x by <u>isolating the variable</u> on the left side:
We now know that x=8, and also that Jared has x+12 books. To find the number of comic books Jared has, let us <u>add</u> 12 to x:
Therefore, Jared has 20 comic books.

Answer:
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
4.25+1.25*m, 5.75+0.75*m
4.25+5.75=10 and 1.25+0.75 = 2 therefore the two expressions are 2m+10
0.5m-1.5 : 4.25+1.25+m-5.75+0.75*m =0.5m-1.5 ( I'm quite sure about this one but I can't think of another answer but this )
Answer:
The answer is 20.8

I hope this is right. Sorry if i'm wrong
Basically, you are looking for the area and volume of a tetrahedron.
Tetrahedron area = sq root (3) * edge^2
Tetrahedron area =
<span>
<span>
<span>
27.7128129211
</span>
</span>
</span>
Tetrahedron volume = [sq root (2) / 12] * edge^3
Tetrahedron volume =
<span>
<span>
<span>
0.1178511302
</span>
</span>
</span>
* 64
Tetrahedron volume =
<span>
<span>
<span>
7.5424723327
</span>
</span>
</span>
<span>
<span>
</span></span>
I don't know exactly what you mean by the "lateral area". I'm guessing it is the area of each face?
If that's the case then it equals <span>
<span>
27.7128129211
</span>
/ 4 = </span><span><span><span>6.9282032303
