Answer:

For the first question the correct form would be B. It would be 6(p-3)=42. For the second question the answer would be 10.

Step-by-step explanation:

For the first question B is correct because it's 3 dollars off which would be -3.

For the second question you would multiply 6 with p and 6 with -3. This would equal to 6p-18. This would make the equation 6p-18=42. You would then add 18 to 42, which equals 60. Finally you would divide 60 by 6, which equals 10, which is your answer.

Ok so I think what you need to be solved is to find h? So I am gonna do that

To find h the first thing you need to do is get the variable h all on one side. So subtract 6.5h from the right side and subtract 5 from the left side. It will then look like this:

0.75h = 5.25

Now you need to isolate the variable so you must divide both side by 0.75 to get h by itself. This should now look like:

h = 7

So now you know that h is equal to 7

You can always check to see if the answer is correct by plugging in 7 for h on both sides and seeing if they equal the same amount.

Hope this helps :)
