It would equal 15. To get 15, you would first do 1*10= which equals 10. After that, you would add 5 to the 10 then there's your answer. I hoped this helped!
De acuerdo con un sistema de ecuaciones, tiene-se que los números son 31 y 84.
----------------
- En el sistema de ecuaciones, tiene-se que los números son x e y.
- Suma de 115, o sea,

- <u>El número mayor es dos veces más 22 unidades que el otro</u>, o sea,

----------------
Primero se encuenta el número menor, <u>reemplazando la segunda ecuación en la primera:</u>





----------------
El número mayor es dado en <u>función de el menor</u>, o sea:

Los números son 31 y 84.

Answer:
d) 4 ± 5i
Step-by-step explanation:
Here we have to use the quadratic formula.
x = 
In the given equation x^2 - 8x + 41 = 0, a =1, b = -8 and c = 41
Now plug in the given values in the above formula, we get
x = 
Simplifying the above, we get
x = 
x = 
[√-100 = √-1 *√100 = i*10 = 10i] because the value of √-1 = i]
x = (8 ± 10i )/2
Now dividing by 2, we get
x = 4 ± 5i
The answer is d) 4 ± 5i
Hope you will understand the concept.
Thank you.
7 would be the number cause;
25 ÷ 7 = 3 r4
hope that helps :D
X-45\x<-4(multiply both sides by X to remove the denominator )
X-45<-4x (collect the like terms)
-45<-4x+x
-45<-3x(divide both sides by -3
-45\-3<-3\-3x
15>x
