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

Answer:
y = -6
Step-by-step explanation:
To simplify this equation as much as possible, we have to get the variable y by itself.
To do this, we would do the inverse operation of subtraction and add 7 to the left and right side of the equation.
-7 + 7 + 5y = -37 + 7
The 7s cancel out on the left side because -7+7 = 0 and so we are left with,
5y = -30
Then we would do the inverse operation of multiplication and divide by 5 on the left and right side of the equation.
5y/5 = -30/5
y = -6
(A) For x representing the cost of one of Tanya's items, her total purchase cost 5x. The cost of one of Tony's items is then (x-1.75) and the total of Tony's purchase is 6(x-1.75). The problem statement tells us these are equal values. Your equation is ...
... 5x = 6(x -1.75)
(B) Subtract 5x, simplify and add the opposite of the constant.
... 5x -5x = 6x -6·1.75 -5x
... 0 = x -10.50
... 10.50 = x
(C) 5x = 5·10.50 = 52.50
... 6(x -1.75) = 6·8.75 = 52.50 . . . . . the two purchases are the same value
(D) The individual cost of Tanya's iterms was $10.50. The individual cost of Tony's items was $8.75.
