What is the value of p in the equation?

One-fourth (8 minus 4 p) + 2 p = 12

Answers

Answer 1
Answer:

1/4(8-4p) + 2p = 12

Use distributive property by multiplying 1/4 by each term inside parentheses:

2 - p + 2p =12

Combine like terms:

2 + p = 12

Subtract 2 from both sides:

P = 10
Answer 2
Answer:

P is equal to 10

How to get your answer:

So 1/4(8-4p) + 2p = 12

First you need to distributive by multiplying 1/4 to each term like this:

2 - p + 2p =12

Then you have to combine to terms just as I did below:

2 + p = 12

Then you need to subtract 2 from both sides to get 10 so:

P = 10

In order to put a number into scientific notation, you multiply or divide the number by multiples of 10 until your base number is between 1 and 10 then you raise the number to the negative or positive exponent in the amount that you used to multiply or divide the number... Let me show you...

0.000000106 millimeter

Every time you multiply by 10, you move the decimal one place to the right. In this case if you multiply by 10 seven times, the decimal moves 7 places to the right. Now you have

1.06 ... but you can't just change a number so you have to show how your number is equivalent to the original number. You do this with the exponents. If you raise the new number to the -7 exponent, it shows you have to move the decimal 7 places to the left to expand to your original number. So the scientific notation would be...
1.06 × 10^-7

*note- if you move the decimal to the left you would have a positive exponent. If you move it to the right you'll have a negative exponent.
0.000000106mm,

We move the decimal point from the left, until it gets to 1.06. And the point moves 7 times.

= 1.06 × 10⁻⁷ mm  in scientific notation.

Which point is on the graph of the equation y = 2x - 5?(3, -1)
(2, -5)
(4, 2)
(2, -1)

Answers

The x in this equation is the first number in the brackets, and the result of the equation is the second number in the brackets.  So all that needs to be done is to substitute x for 3, 2 and 4 and see which one has the correct answer. 
3 X 2 = 6.  6 - 5 = 1  (3, 1)
2 X 2 = 4.  4 - 5 = -1 (2, -1)
4 X 2 = 8.  8 - 5 = 3  (4, 3)

The only one of those coordinates that are the same as any of the given answers are (2, -1).  Therefore, that is the answer.

12.24 divided by 0.34

Answers

12.24 divided by 0.34 =36
12.24÷0.34= 0.36. Because 34×3= 102 so 12.2 minus 102= 204 then you do 34 × 6= 204 so 204 minus 204 = 0
