Answer:
w = 3
Step-by-step explanation:
Δ BDE and Δ BAC are similar, then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
5w = 3(w + 2) ← distribute
5w = 3w + 6 ( subtract 3w from both sides )
2w = 6 ( divide both sides by 2 )
w = 3
Answer:
Step-by-step explanation:
Los movimientos bancarios de Santiago se representan matemáticamente teniendo en cuenta que consignar es sumar y retirar el restar. Por lo tanto podes expresar los movimientos bancarios de la siguiente manera:
- Lunes → + 300.000
- Martes → -120.000
- Miércoles → -95.000
- Jueves → +80.000
Al realizar la sumatoria se obtiene:
+300.000 - 120.000 - 95.000 + 80.000 = + 165.000
En la semana Santiago obtiene en su cuenta bancaria $165.000
Answer:

2y - 8x = 0
-----------------
10x = 30
x = 3
y= 12

Hey there!
I believe your answer should be: OPTION B. because
7x + 2y - 14z = 56
7(8) + 2(28) - 14(4) = 56
56 + 56 - 56 = 56
112 - 56 = 56
56 = 56
So, that’s why possibly Option B. could be your result
Good luck on your assignment & enjoy your day!
