Ava used the following equation in order to solve a math problem involving integers.

AnnZ [28]

Answer:

The only equation which is incorrect is in option B.

Step-by-step explanation:

Eva used the following equation in order to solving integers, which is

$\frac{-h}{-k} = j$

⇒ $j = \frac{h}{k}$ ......... (1)

Now, if the equation Ava used is correct, then we have to find which of the given equations is not correct.

Now, in option A) it is given that $- j = \frac{- h}{k}$

⇒ $j = \frac{h}{k}$ which is same as equation (1).

In option B) it is given that $- j = \frac{- h}{- k}$

⇒ $j = - \frac{h}{k}$ which is not same as equation (1).

In option C) it is given that $- j = \frac{h}{- k}$

⇒ $j = \frac{h}{k}$ which is same as equation (1).

Again, in option D) it is given that $j = \frac{h}{k}$

⇒ $j = \frac{h}{k}$ which is same as equation (1).

Therefore, the only equation which is incorrect is in option B. (Answer)

Can someone solve this real quick?

Fudgin [204]

Answer:

n = -4

Step-by-step explanation:

Start off by remembering PEMDAS which first P means parenthesis so use distributive property to multiply the 2n + 4 by the 3 in front of it and do the same to the n + 1 and multiply that by the 5 in front which turns your question into 6n+12-2=1+5n+5 so now i'd combine like terms on both sides which now gives you 6n + 10 = 5n +6 so now to get the n on one side i'm going to sub tact it from both sides doesnt matter which one you do but to make it easier i'd subtract the 5n from the 6n because the whole point is to solve for n and by doing that you'd already be getting it by itself. so now the question should look like n + 10 = 6 so subtract 10 from both sides to isolate the n and you get your answer n = -4
