Hugo is building a deck. He has
Liula [17]

Answer:

3 pieces from each board

Step-by-step explanation:

Givens

12 pieces of wood each 10 1/2  feet long

required: each piece will produce x number of wood 3 1/4 feet long.

Formula

number of pieces = 10 1/2 - x * 3 1/4             x is an integer.

Solution

The formula must produce a length that is less than 10 1/2.

The only way I can think to do this is by guessing until you get a number greater than 10 1/2 and then subtract 1 from that value of x.

Let x = 4

number of pieces = 10 1/2 - 4 * 3.25

number of pieces = 10 1/2 - 13

number of pieces = - 2 1/2                The board is too short to give 4 pieces each one of which is 3 1/4. You would need a board that is 2 1/2 feet longer.

4 is too many. So try 3

number of pieces = 10 1/2 - 3 * 3 1/4

number of pieces = 10 1//2  - 9 3/4

number of pieces = 3/4                  The board will produce 3 pieces that are 3 1/4  feet loong. 3/4 of a foot is waste.

Each board produces 3 pieces

There are 12 boards

Therefore 3 * 12 = 36 pieces

6,2 reflected over the x axis.

2=-2

Y axis rule example

-2,7 reflected over the y axis

-2=2

Step-by-step explanation:

If it ever says (example,example) like flipped over the x, it will change the y.

How to solve -7-8(6x+5)
koban [17]

Answer: -47 - 48x

Step-by-step explanation: When you first take a look at this problem, it's tempting to want to subtract -7 - 8 to get -15 and then distribute the -15 through the parentheses.

You wouldn't want to subtract however before you distribute because the distributive property is a form of multiplication and remember from your order of operations that multiplication comes before subtraction.

So the first thing you want to do here is distribute and change the minus sign in front of the -8 to plus a negative 8 so that you know you are distributing a -8 through your parentheses.

So we have -7 + -8 times 6x which is -42x + -8 times 5 which is -40.

Now we have -7 + -48x + -40.

Now just combine your like terms. -7 + -40 is -47 and plus a negative 48x can be written as -48x so we have -47 - 48x.

So your answer is just -47 - 48x.
