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

seropon [69]

Answer:

13.50=0.75(x+10)

Step-by-step explanation:

From the options given, it seems the price of either of Sandals or sneakers is given as 10 and the other is x

If Price of Sandals or sneakers=x

And the price of the other one is 10

Total price=(x+10)

25% discount is given

So she will pay 75% of the total cost

75%=0.75

Total cost =$13.50

She would pay 75% of (x+10)

Which is

0.75(x+10)=13.50

13.50=0.75(x+10)
