Answer:

x = 2

Step-by-step explanation:

Given

3x + 1 = x + 5

Subtract x from both sides

3x - x + 1 = x - x + 5

2x + 1 = 5

Subtract 1 from both sides

2x + 1 - 1 = 5 - 1

2x = 4

Divide both sides by 2

x = 4/2

x = 2

Answer:

x=2

Step-by-step explanation:

3x+1=x+5

Subtract x from each side to get all the variables on one side

3x-x+1=x-x+5

2x+1 = 5

Subtract 1 from each side to get all the constants on the other side

2x+1-1 = 5-1

2x= 4

Divide each side by 2

2x/2 =4/2

x =2

Create an item with a selling price over $100 a discount of 25% and tax is 9%
Lana71 [14]

First, convert the 25% to a real mathematical number. For percents, this is always done by dividing the 25% by 100%, or 25% / 100% = 0.250.

Second, find out what 25% of $100 is. This is the amount of the sale discount. This is always found by mulitplying 0.250 by the item's cost $100, like this:

0.250 x $100 = $25.00.

So for this sale, you'll save $25.00 on this item.

This means, the cost of the item to you is

$100 - $25.00 = $75.00.

Alternatively, you can think about it this way. The item is 25% off. This means you'll pay 75.000% of the total cost (100% - 25% = 75.000%).

Now what's 75.000% of the total cost?

0.750 x $100 = $75.00.

Just like the result above, the sale price on the item is $75.00.

Hope this helps you on your assignment! :)
