How do I decease 7 by 3%​
FromTheMoon [43]

Answer:

6.79

Step-by-step explanation:

First of all, you will have to know how much is 3% of 7 in order to decrease it by that amount.

7 x 0.03 = 0.21

Now that you know the amount, you can subtract it from seven and therefore you have decreased 7 by 3%.

7 - 0.21 = 6.79

Arte-miy333 [17]

Answer:

No Solutions

Step-by-step explanation:

We have to create an equation to be able to solve this problem.

Let's let x = the # of home runs

The equation that helps us solve this is 5 + 1x = 10 + 1x

First, we have to subtract 1x from each side (always subtract the variable first before the constant, math rule)

This brings us to 5=10 because the x's cancel each other out.

You probably look at this saying, wait, this isn't right, and you would be correct

Since this equation isn't true, it is No Solutions

No Solutions mean there is no answer to the problem, it is impossible to solve.

So, our final answer is No Solutions

Hope this helps, have a great day! :)
