Answer:
x = -3
Step-by-step explanation:
3(4x + 8) = - 35+23
Combine like terms
3(4x + 8) =-12
Divide by 3
3/3(4x + 8) = -12/3
4x+8 = -4
Subtract 8 from each side
4x+8-8 = -4-8
4x = -12
Divide by 4
4x/4 = -12/4
x = -3
You have to distribute the 3 first then combine like terms and divide to get n by itself so n=1/2
Evaluando una ecuación exponencial, veremos que luego de 5 años el capital se convierte en $12,884.08
<h3>¿En cuánto se convierte el capital?</h3>
Esta situación se podra modelar con la ecuación exponencial:
f(n) = $8,000*(1 + 10%/100%)ⁿ
Donde n es el número de años.
Podemos simplificar la ecuación para obtener:
f(n) = $8,000*(1.1)ⁿ
Ahora queremos ver el valor que toma esto cuando n = 5, asi obtenemos:
f(n) = $8,000*(1.1)⁵ = $12,884.08
Así que luego de 5 años, el capital se convierte en $12,884.08.

Answer: </h3><h3>Fred has <u>20 students</u> and Lee has <u>22 students</u></h3>
=============================================================
Work Shown:
L = number of students in Lee's class
F = number of students in Fred's class
Lee has 1.1 times as many students compared to Fred
This means we have this equation
L = 1.1F
Whatever the value of F is, we multiply that by 1.1 to get the value of L
The two amounts L and F add to 42 total students
L+F = 42
1.1F + F = 42 .... replace L with 1.1F
2.1F = 42
F = 42/(2.1)
F = 20 .... Fred has 20 students
L = 1.1*F
L = 1.1*20
L = 22 .... Lee has 22 students
------------
Check:
L+F = 22+20 = 42
this confirms the answer
Answer: d) 5/7
Step-by-step explanation:
10 out of 35 of the students are girls. The number of boys is therefore:
= 35 - 10
= 25 boys
Probability that the winner is a boy is:
= 25/35
Take that fraction to the simplest by dividing both by 5:
= 5/7
