Answer:
x = 8
Step-by-step explanation:
5(x-2)=30
Distribute
5x- 10 = 30
Add 10 to each side
5x-10+10 = 30+10
5x= 40
Divide by 5
5x/5=40/5
x = 8
Divide the sides of the larger triangle by the corresponding side of the smaller one:
18/7.2 = 2.5
Figure A is 2.5 times the size of figure B
The scale factor is 2.5

$10.50
10 Tickets would be $105.00
$105.00 - $10.50 = $94.50 so 9 Tickets would be $94.50
$105.00 + $94.50 = $199.50
$205.00 - $199.50 = $5.50 which isn't enough for another ticket.
10 Tickets + 9 Tickets = 19 Tickets.
You need to isolate x, which means you need to get it alone. 16x and 11x are like terms because they both have an x, do subtract them. 16-11=5. So 15 = 5x
Then to turn 5x into x, divide by five. This is because 5/5 is 1, and 1x is x. Divide both sides, so
X = 3
