I’ll solve number 3.

You need to group the like terms. For example, -4n + 6n = 2n

8=2n

Now, we need to keep n by itself.
2n/2 = n

Whatever you do to one side, you need to do to the other.

8/2 = 4

So, in conclusion, n = 4.

I hope this helps for you to solve the rest!

The Table Shows a proportional relationship between x and y for each Value of x and y match it to the correct unit rate y/x in i

Elden [556K]

The correct proportions are given as follows:

x = 3, y = 27: 9/1.

x = 9, y = 81: 9/1.

x = 21, y = 126: 6/1.

x = 14, y = 84: 6/1.

x = 12, y = 36: 3/1.

x = 15, y = 45: 3/1.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The proportions for this problem are given dividing y by x, hence:

x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.

x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.

x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.

x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.

x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.

x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.
