Answer:
13=x
Step-by-step explanation:
Side-spliting theorem
21/(x-4)=14/6
cross multiply
21*6=14*(x-4)
distribute 14
126=14x-56
add 56 to both sides
126+56=14x-56+56
leaving you with
182=14x
Divide both sides by 14 to get x by itself
182/14=14x/14
13=x
Answer:
5.3
Step-by-step explanation:
Use Pyth Theorem
a^2 + b^2 = c^2
6^2 + b^2 = 8^2
36 + b^2 = 64
b^2 = 28
Sq root of 28 = 5.3
Answer:
<h2>The total value of all the letters in the alphabet is 676.</h2>
Step-by-step explanation:
The problem is about an arithmetic sequence where the difference is 2, the first term is 1 and we know that the alphabet has 26 letters.
To find the total sum of all values, we have to use the following formula

Where
,
and
. Replacing values, we have

Therefore, the total value of all the letters in the alphabet is 676.
Usando las relaciones entre velocidad, distancia y tiempo, se encuentra que ella condujo a una velocidad media de 90,5 km/h.
--------------------------
La <u>velocidad </u><u>es la distancia dividida por el tiempo</u>, por lo que:

- Total de 135,75 km, o sea,

- Llego en 1,5 horas, o sea,

La velocidad es:

División de decimales, o sea, seguimos multiplicando los números por 10 hasta que ninguno sea decimal:

Ella condujo a una velocidad media de 90,5 km/h.
