La esculturas triangulares tendrán las siguientes medidas 16.66 cm, 40 cm y 23.32 cm.
<h3>¿Qué e el perímetro?</h3>
Es la suma total de los lados del triángulo, en este caso el perímetro total es de 80.
<h3>¿Cómo calcular las dimensiones del triángulo?</h3>
Se pueden calcular usando el total y la información sobre cada lado:
- x+4 + 3x+2 + 2x-2 = 80
- 6x + 4 = 80
- 6x = 80 - 4
- 6x = 76
- x = 76/ 6
- x = 12.66
Finalmente calcule cada lado:
- A. x+4 = 12.66 + 4 = 16.66
- B. 3x + 2 = 3 x 12.66 + 2 = 39.98 o 40
- C. 2x - 2 = 23.32

5t/3-2/3*(t+4)=1
5t/3-2t/3+8/3=1
3t/3+8/3=1
8/3-1=t
8/3-3/3=t
5/3=t
<span>3/4x - 4/5 = 1/2x + 1
</span>3/4x - 4/5 = 2/4x + 1
3/4x - 2/4x = 1 + 4/5
1/4x = 9/5
x = (9x4) / (5x1)
x = 36/5
x = 7 1/5
Answer:
x = 5
Step-by-step explanation:
4x + 2y + z = 24
2x - 3y - z = 2
5x + y + 2z = 21
-----------------
Eliminate z
Add the 1st and 2nd eqn
4x + 2y + z = 24
2x - 3y - z = 2
----------------
6x - 1y = 26 eqn A
Multiply the 2nd eqn by 2, then add the 3rd.
4x - 6y -2z = 4
5x + y + 2z = 21
----------------
9x - 5y = 25 eqn B
---------------
Now you have 2 eqns in 2 unknowns, not 3.
Multiply eqn A by 5 and subtract eqn B.
30x - 5y = 130 eqn A times 5
9x - 5y = 25 eqn B
-------------
21x = 105
x = 5
