Step-by-step explanation:The cost of an adult ticket to the show is $5.5
The cost of a student ticket to the show is $4.25
A family is purchasing 2 adult tickets and 3 student tickets. This means that the total cost of 2 adult tickets would be
2 × 5.5 = $11
It also means that the total cost of 3 student tickets would be
3 × 4.25 = $12.75
The total cost of 2 adult tickets and 3 student tickets would be
11 + 12.75 = $23.75
If the family pays $25, the exact amount of change they should receive is
25 - 23.75 = $1.25
Answer:
See below.
Step-by-step explanation:
p^2 + 2
= (6n + 1)^2 + 2
= 36n^2 + 12n + 1 + 2
= 36n^3 + 12n + 3
= 3(12n^2 + 4n + 1).
- which is divisible by 3.
Answer:
See explanation below.
Step-by-step explanation:
Take the original number and move the decimal from right to left, one place at a time. Stop just next to the last number, and count the number of times you moved the decimal. The number of times it moved is the exponent of 10. See examples below:
285 is the same as 2.85 x 10^2
3721 is the same as 3.7 x 10^3
88700000 is the same as: 8.87 x 10^7
Hope this helps!! Have an Awesome Day!! :-)
Answer:
Step-by-step explanation:
Recall that we say that d | a if there exists an integer k for which a = dk. So, let d = gcd(a,b) and let x, y be integers. Let t = ax+by.
We know that 
so there exists integers k,m such that a = kd and b = md. Then,
. Recall that since k, x, m, y are integers, then (kx+my) is also an integer. This proves that d | t.
