Answer:
adjacent, linear pair, supplementary
Step-by-step explanation:
adacent because they are angles side by side
linear because the angles create a straight line
supplementary because the angles equal 180 degrees
Remove the parentheses
x^3-9x^2+27x-27-x^3+3x^2-3x+1+7x^2=21x-28
x^2+24x-26=21x-28
x^2+24x-26-21x+28=0
x^2+3x+2=0
factor the expression
(x+2)(x+1)=0
sooo x1=-2 x2=-1
The radius is always half the diameter. So, your answer is A.
1.one and seventy five thousandths this is word form 2.(1 x 1) + (0/10) + (7/100) + (5/1000) this is expanded form
Answer:
$36 (see below)
Step-by-step explanation:
First, you have to find how much they paid for one ticket.
If they paid $12 for 3, then they paid $4 for 1.
You could've also use a ratio:
$12 $x
-------- = --------
3 1
Cross multiply:
$12 (1) = $3x
$12 = $3x
$4 = x
So $4 for 1 ticket.
To find the cost of 9 tickets, just multiply the price by the number of tickets, which is:
$4 (9) = $36
