Step-by-step explanation:
Answer:
615 children tickets
195 adults tickets
Step-by-step explanation:
Let the number of children’s tickets be c and the number of adult tickets be a.
Children’s ticket is $3 and adult’s is $5 for a total of $2,820. This means:
3c + 5a = 2,280
This is the first equation.
The number of children’s tickets sold is 30 more than 3 times that of the adults. This means
c = 3a + 30.
This is equation ii. We now substitute ii into I to yield:
3(3a+ 30) + 5a = 2,820
9a + 90 + 5a = 2,820
14a + 90 = 2,820
14a = 2820 - 90
14a = 2730
a = 2730/14 = 195 tickets
c = 3a + 30
c = 3(195) + 30 = 615
Let's assume that the Length of the rectangle is (2x-5)m and The breadth of the rectangle is (2x+60)m.
Now, note that to find the perimeter of a shape requires the sum of all of its sides. In this case, A rectangle has 2 Lengths and 2 Breadths. Thus, the perimeter of the rectangle is
2(2x-5)+2(2x+60)=( 4x-10)+ (4x+120)
= 8x+110
We don't stop there, the question says if the value if x is 12m
So, we substitute X into 12
8(12)+110= 96+110
=206
To solve this you need to take the answer from the previous iteration.
Iteration 1: The answer is given
a1 = 300
Iteration 2: Solve using the equation. a(n-1) is the answer from the previous iteration. n = the number of the current iteration. So, a(n-1) = 300 and n = 2
a2 = 300/2 = 150
Iteration 3: a(n-1) = 150 and n = 3
a3 = 150/3 = 50
Iteration 4: a(n-1) = 50 and n = 4
a4 = 50/4 = 12.5
Answer: 12.5
