                                                             <u>1/2(x-4) = 4</u>

Multiply each side of the equation by  2 :  (x- 4) =  8

Add  4  to each side of the equation:          <em>x      = 12</em>

1/2(x-4)=4 
1/2x-2=4 (expand the brackets)
1/2x=6 (added 2 to both sides)
x= 6/(1/2)
x= 6*2
x=12

Mark buys a wooden board that is 7 1/2 feet long. The cost of the board is $0.50 per foot, including tax. What is the total cost
artcher [175]

Answer:

Total cost of Mark's board is $3.75.

Step-by-step explanation:

We are given the following in the question:

Length of wooden board =

=7\dfrac{1}{2}\text{ foot}

Unit cost of board = $0.50 per foot

Total cost of board =

=\text{Length of board}\times \text{Unit cost of board}\\\\=7\dfrac{1}{2}\times 0.50\\\\=\dfrac{15}{2}\times \dfrac{1}{2}\\\\=\dfrac{15}{4} = 3.75\$

Thus, total cost of Mark's board is $3.75.

ki77a [65]

Answer:

125%

Step-by-step explanation:

lets just say the book is $100. 20% less would be $80
now to go back to $100, we need to add $20 to $80
20 is 25% of 80, so add the extra 25% to 100% of 80
