Answer:
350
Step-by-step explanation:
Let the number of adult tickets be x, then the number of student tickets sold would be (x–54).
We now have
x+(x–54)=646
2x=700
x=350
Therefore, 350 adult tickets were sold.
Answer:
A) x+5
B) 121
Step-by-step explanation:
A) If Tim is 5 pounds heavier than Amy, an equation for this situation can be modeled by x+5, where Amy is <em>x </em>pounds.
B) If Tim is 126 pounds, then Amy's weight is 126-5=121 pounds.

Step-by-step explanation:
The common difference (d) = 2
The first element (a) = 3.
So, the n-th term is
I = a + (n-1).d
= 3 + (n-1)×2
= 1 + 2n.
So the required sum is
= (n/2)(a + I)
= (n/2)( 3 + 1 + 2n)
= (n/2)(4 + 2n)
= n (n+2)

Answer:
m=2 and b=8
Step-by-step explanation:
this is a linear equation, which takes on the formula of y=mx+b
therefore in the equation y=2x+8, 2 is the m, and 8 is the b
Answer:
≈$4607
Step-by-step explanation:
I will assume it's compounded yearly.
Apply the compound interest formula.
![A=P(1+\frac{r}{n})^{nt}](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D)
A = Total
P = Initial Principle
r = Interest Rate
n = number of interest in every t period
t = number of periods
In the case,
P = 3500
r = 3.1% = 0.031
n = 1
t = 9
Hence,
![A=3500(1+\frac{0.031}{1})^{1*9}](https://tex.z-dn.net/?f=A%3D3500%281%2B%5Cfrac%7B0.031%7D%7B1%7D%29%5E%7B1%2A9%7D)
![A = 4606.764717......](https://tex.z-dn.net/?f=A%20%3D%204606.764717......)
A ≈ 4607 (nearest whole number)
