Answer:10%= 310

5%= 155

15%=465

Step-by-step explanation: Solution for what is 15% of 3100

3100/x=100/15

(3100/x)*x=(100/15)*x - we multiply both sides of the equation by x

3100=6.66666666667*x - we divide both sides of the equation by (6.66666666667) to get x

3100/6.66666666667=x

465=x

x=465

Which equation has a solution of n = 4?

Allushta [10]

Answer:

D. 7n = 28

Step-by-step explanation:

Let's substitute 4 for n in each equation to check if it the resulting equation is correct:

$6+n=24\\ 6+4=24\\ 10\neq 24\rightarrow \text{Incorrect!}$

$5n=54\\5(4)=54\\20\neq54\rightarrow\text{Incorrect!}$

$12-n=16\\12-4=16\\8\neq16\rightarrow\text{Incorrect!}$

$7n=28\\7(4)=28\\28=28\rightarrow\text{Correct!}$

Therefore the answer is D
