Answer:
There were 40 student tickets sold.
Step-by-step explanation:
First I set up equations to represent this situation.
4x+3y=380
x+y=105
x represents the adult tickets and y represents the student tickets.
I can solve this with the elimination method. I want to cancel out the x so I will multiply every term in equation 2 by -4.
4x+3y=380
-4x-4y=-420
Now I combine like terms.
-y=-40
I can divide the negative one from both sides.
y=40
Answer:
x = 0
Step-by-step explanation:
First we need to move either 5r or 2r to the other side, in order to isolate the variable.
We'll move 5r, in this case, by subtracting it from 2r. Now we got: -11 - 3x = -6 - 5.
Next we subtract 5 from -6 to get
-11 - 3x = -11.
Now we can add 11 on both sides to get -3x = 0.
Finally divide by -3 to get x = 0.
Hope this helps :)

Answer:
Length of RU is 20 units.
Step-by-step explanation:
In ΔRSt and ΔRUT,
ST ≅ TU [Given]
RT ≅ RT [Reflexive property]
∠RTS ≅ ∠RTU [Both the angles are the right angles]
ΔRTS ≅ ΔRTU [By SAS property of congruence]
Therefore, RS ≅ RU [By CPCTC (corresponding parts of the congruent triangles are congruent]
8x = 6x + 5
8x - 6x = 5
2x = 5
x = 2.5
Length of RU = (6x + 5)
= 6(2.5) + 5
= 15 + 5
= 20
Length of RU is 20 units.
If A and B are independent, then P(A and B) = P(A) * P(B).
Then the probability that A occurs given that B occurs, for example, reduces to the probability that A occurs by itself:

So all you need to do is check that P(A|B) = P(A). If so, then A and B are independent. This is true only for the second case.
