PSYCHO15rus [73]
We know the number of faces and vertices of the solid and we have to calculate the number of edges.We have : F = 16 and V = 14.The formula is:F - E + V = 216 - E + 14 = 216 + 14 - 2 = EE = 30 - 2E = 28Answer: The solid has 28 edges.

4t+3c=$81.00<br> 10t+3c=$135.00
muminat
\left \{ {{4t+3c=81.00\:(I)} \atop {10t+3c=135.00\:(II)}} \right.
<span>Simplify the first equation by (-1)
</span>\left \{ {{4t+3c=81.00\:*(-1)} \atop {10t+3c=135.00\:\:\:\:\:}} \right.
<span>Once simplified, cancel the opposing terms.
</span>\left \{ {{-4t-\diagup\!\!\!\!3c=-81.00} \atop {10t+\diagup\!\!\!\!3c=135.00}} \right.
Now find the value of "t".
\left \{ {{-4t=-81.00} \atop {10t=135.00}} \right.
-------------------------------
6t = 54.00
t =  \frac{54.00}{6}
\boxed{\boxed{t = 9.00}}\end{array}}\qquad\quad\checkmark

Now find the value of "c", replace the found value of "t" in the first equation:
4t+3c=81.00\:(I)
4*9+3c=81.00
36 + 3c = 81.00
3c = 81.00 - 36
3c = 45.00
c =  \frac{45.00}{3}
\boxed{\boxed{c = 15.00}}\end{array}}\qquad\quad\checkmark

Answer:
<span>The values ​​of "t" and "c" satisfying the linear system are successively: $ 9.00 and $ 15.00</span>
