Assuming the triangle ABC is equal to the triangle QRS means that their sides will have the same size.
So the side AB is the same as QR. As well as BC is the same size as RS; AC is the same as QS.
So, if AB = QR that means that both have 50 cm.
Answer: 50 cm
Answer: 25 minutes
Step-by-step explanation:
Well, since it's already set up, all we do is divide -6 by 3/4 to get our x
So that means x=-8
Answer:

Step-by-step explanation:
simplify

to

then
-0.05 × 120 = -6
then we have our answer
-6√2
You can set up a system of equations for this problem. x= number of coach tickets and y = number of first class tickets.
$210x + $1200y = $10,230 (cost of coach ticket plus cost of first class tickets is total budget)
x + y = 11 (number of coach tickets plus number of first class tickets is total number of people)
Solve the second equation for y to get y = 11 - x, then plug that into the first equation and solve for x:
$210x + $1200(11 - x) = $10,230
$210x + $13,200 - $1200x = $10,230
-$990x + $13,200 = $10,230
-$990x = $2,970
x = 3
Sarah bought x = 3 coach tickets. Plug that into the second equation and solve for y:
3 + y = 11
y = 8
Sarah bought y = 8 first class tickets.
