What are the following rates?
Answer:
x =4.5
Step-by-step explanation:
this is an isosceles triangle
the legs are equal
4x + 6 = 6x - 3
subtract 6 from both sides
4x +6 - 6 =6x - 3 - 6
4x = 6x - 9
subtract 6x from both sides
4x -6x = 6x - 6x -9
-2x = -9
divide both sides by -2
-2x /-2= -9/-2
x =4.5
Cecilio tiene "x" años y Jonathan tiene "y" años.
Tres veces la edad de Cecilio es 3x y 3x es 48 años mas que "y".
3x = y + 48
Jonathan tiene un tercio de la edad the Cecilio.
y = x/3
3x = y + 48 se sustituye x/3 por y
3x = x/3 + 48
3x - x/3 = 48
9x/3 - x/3 = 48
8x/3 = 48
x = 48 * 3/8
x = 18
Cecilio tiene 18 años.
y = x/3 = 18/3 = 6
Jonathan tiene 6 años.
