Answer:
I. Hijo, h = 10 años 
II. Padre, P = 40 años
Step-by-step explanation:
- Sea la edad del padre P. 
- Sea la edad del hijo h. 
Traduciendo el problema verbal a una expresión algebraica, tenemos; 
P = 4h .....ecuación 1.
P + 5 = 3(h + 5) ........ecuación 2.
Simplificando aún más, tenemos; 
P + 5 = 3h + 15 
P = 3h + 15 - 5 
F = 3h + 10 ......ecuación 3.
Sustituyendo la ecuación 1 en la ecuación 3; 
4h = 3h + 10 
4h - 3h = 10 
<em>h = 10 años </em>
A continuación, encontraríamos la edad del padre; 
P = 4h
P = 4 * 10 
<em>P = 40 años</em>

Answer:
The value of m is 3 because (5^4)^3 = 244140625 and 5^12 = 244140625 also, this means they are both equal to each other. Another way of getting the correct answer is just seeing what times 4 will get you 12, as you can see
3 x 4 = 12. 
So yea the answer is M = 3.

Answer:
x=20 and y=100
Step-by-step explanation:
Using vertical angles, angle 1 and 3 equal each other. Therefore, x=80/4. Then, by using the sum of angle 1 and 3, 160, and using vertical angles again, we can find angle 2, which is (360-160)/2.
