<h3>
Answer: B) 2/3</h3>
====================================
Explanation:
The order is important for ABC and XYZ so we can see what letters pair up.
- A pairs with X since they are the first letters
- B pairs with Y since they are the second letters
- C pairs with Z since they are the third letters
Based on that, we can see that AB pairs with XY as they are the first two letters of ABC and XYZ respectively.
Divide the length XY over AB and reduce
XY/AB = 10/15 = 2/3
We could also divide XZ over AC
XZ/AC = 14/21 = 2/3
and we get the same ratio

Step-by-step explanation:
Responder:
La temperatura bajó 12 °
Explicación paso a paso:
Dado que:
Temperatura en la noche = + 2 ° (2
Temperatura de la mañana = - 12 (12 ° bajo cero).
La diferencia de temperatura entre la noche y la madrugada:
Temperatura nocturna - temperatura por la mañana temprano
2 - (-12)
2 + 12 = 14
Hay una diferencia de temperatura de 12 °. La temperatura bajó 12 ° entre la noche y la madrugada.
Answer:12
Step-by-step explanation:
Let the numbers be a and b
a-3b=5 ........equation (1)
There product is :
ab=68 ..........equation (2)
From equation (1)
a-3b=5
Make a the subject of the formula
a=5+3b. ........equation (3)
Substitute equation (3) into equation (2)
(5+3b)b=68
3(b^2)+3b-68=0
The product is -204b^2(17 and -12)
(b+17)(b-12)=0
b=-17 or b=12
So the number is 12
