Answer:
X=-2
Y=-6
Step-by-step explanation:
Since both equations are already expressed in the simplest form of y, then we equate them to be equal hence
x-4=4x+2
Bringing like terms together
-4-2=4x-x
Solving both sides
-6=3x
Making x the subject then
X=-6/3=-2
Subsrituting the value of x into any of the initial equations
Y=x-4 then y=-2-4=-6
Therefore, the solution is
X=-2
Y=-6
A= adult ticket c=child ticket
1. 6a+4c=88
12a+9c=186
2. so you need to multiply the top number by -2 so you can cancel out the 12a
-2(6a+4c=88)=. -12a-8c=-176
3. then you add them all together
12a+9c=186
-12a-8c=-176
——————————-
c=10
4. now you have to find ‘a’
6a+4(10)=88
6a+40=88
-40. -40
6a=48
divide both sides by 6
a=8
And your final answer should be (8,10)

Answer:
P = 57/1105
P = 0.052
Step-by-step explanation:
Given:
Total number of dummy tickets = 20
Total number of tickets with value = 10 + 10 + 12 = 32
Total number of tickets in the box = 20 + 32 = 52
The probability of picking 3 tickets randomly from the box without replacement and the three are dummy (with no value) is;
P = 20/52 × 19/51 × 18/50
(As each one is picked it reduces the total number of tickets and also the number of dummy tickets by one)
P = 57/1105
P = 0.052
