Just wondering If I'm am doing this correctly. Would like a in depth explanation 7/100 = 3.5/n

n=50

Step-by-step explanation:

7/100 = 3.5/n

The fastest way to do this you can set up proportions.

7n=3.5*100 (you multiply mean and extreme)

7n=350 (you move 2 decimal places to the right)

n=350/7

n=50

n = 50

Step-by-step explanation:

There are two ways you can do it.

1. 7/100 = 3.5/n      You can cross multiply

  7n = 100*3.5

  7n = 350

  n = 50

2. 7/100 = 3.5/n

   7 divided by 2 = 3.5

   100 divided by 2 = 50

I hope this helped and please mark me as brainliest!

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
