Three times a number is the same as 28 more than 6 times the number. Find the number. If n is "the number," which equation could

aksik [14]

Answer:

3n = 6n + 28

Explanation:

The number we are dealing with is "n"

We will proceed by converting the English into Math:

1- Three times the number = 3 * n = 3n

2- Six times the number = 6 * n = 6n

3- 28 more than 6 times the number means that we will add 28 to the value 6n. This will give 6n + 28

Finally, we are given that:

3n is the same as (6n + 28). This means that they are both equal.

Therefore, our equation would be:

3n = 6n + 28

Hope this helps :)

ANSWER

Biodiversity index = 0.096

EXPLANATION

Given 7 different organisms with their individual numbers.

Biodiversity Index is:

$\text{ }\frac{Total\text{ number of species}}{Total\text{ number of individuals in the area}}$

i.e:

$\begin{gathered} Biodiversity\text{ Index = }\frac{7}{15+2+30+1+4+16+5} \\ \text{ = }\frac{7}{73} \\ \text{ = 0.09589} \end{gathered}$

Hence, the Biodiversity Index of Fraya's local park is 0.096. This is a low biodiversity since it's closer to 0.

What is 3n-2/5=7/10 solve please

Tems11 [23]

Answer: $\bold{n=\dfrac{11}{6}}$

Step-by-step explanation:

$\dfrac{3n-2}{5}=\dfrac{7}{10}\\\\\\10(3n-2)=5(7)\qquad \longrightarrow \quad \text{(cross multiplied)}\\\\30n-20=35\qquad \longrightarrow \quad \text{(distributed)}\\\\30n=55\qquad \longrightarrow \quad \text{(added 20 to both sides)}\\\\n=\dfrac{55}{30}\qquad \longrightarrow \quad \text{(divided 30 from both sides)}\\\\n=\dfrac{11}{6}\quad \longrightarrow \quad \text{(simplified fraction)}\\\\\\\large\boxed{n=\dfrac{11}{6}}\\$
