Answer:
$9
Step-by-step explanation:
'Jonathan and 5 friends' would equal <u>6 people paying</u>
Since the total amount was 54 dollars, the equation will be:
$54 ÷ 6 friends
54 divided by 6 is $9
Check:
6 x 9 = 54
For this case we have the following variable:
p: cost of the item that Arthur wants to buy before tax
The expression for the 6% tax is given by:
Or equivalently:
Therefore, two different expressions for the total cost are:
Expression 1:
Expression 2:
To prove that they are equal, suppose that the item costs $ 100:
Expression 1:
Expression 2:

Since the cost is the same, then the expressions are the same.

Answer:
Step-by-step explanation:
{y2+8y−128=0x=34⋅(y+4) ... The two right triangle are similar, so: BDAB=DEAC. From this, I obtain: ... AC=3x AB=4x (3x)²+(4x)²=225 x=3 BD=8 AB/AC=BD/DE 12/9=8/DE DE=6.
