Datos:
Subió 8 pisos
Piso final= 7
Explicación:
Para resolver el enunciado, se debe tener en cuenta que:
Piso final - Piso inicial= 8
Reemplazando y despejando:
7-Piso inicial= 8

Answer:
12
Step-by-step explanation:
The least common multiple (LCM) of 3 and 4 is 12. Adam would have to divide each rectangle into a minimum of 12 parts.
_____
His shading would be 4 parts (4/12 = 1/3) of one of them and 3 parts (3/12 = 1/4) of the other.
__
3 and 4 have no common factors, so their LCM is their product. 3×4 = 12.
Answer: x = 10°
(2x + 50) = 70°
(3x - 10) = 20°
Steps:
(2x + 50)° + (3x -10)° = 90°
2x + 50 + 3x - 10 = 90°
5x + 40 = 90°
5x = 50°
x = 10°
(2x + 50)
2(10) + 50
20 + 50
70
(3x - 10)
3(10) - 10
30 - 10
20
Check:
70 + 20 = 90
90 = 90 ✅
