let y = boat ride ticket
x + y = 10
4x + 3y = 37
x = 10 - y
4x + 3y = 37
4(10-y) + 3y = 37
40 - 4y + 3y = 37
-y = 37 - 40
-y = -3
y = -3/-1
y = 3
x = 10 - y
x = 10 - 3
x = 7
x = 7 ; y = 3
4x + 3y = 37
4(7) + 3(3) = 37
28 + 9 = 37
37 = 37

Answer:
$12.72 or $25.44
Step-by-step explanation:
if he buys 2 tickets that are $12 each. half of 12 is 6 so you will have to pay 12 plus tax(6%). to find tax you would multiply 12 x .06 which would be $12.72. if it say the tickets are half off from $24 being $12 each then the answer would be $25.44. the question dosent specify that.
hope i helped
Final answer:
The total cost after the discount and taxes would be $13.44.
Explanation:
To find the total cost after the discount and taxes, we first need to determine the discount amount.
Since the tickets are on sale for 1/2 price, the discount would be half of the original cost of the tickets.
So the discount amount would be 1/2 * $12 * 2 = $12.
Next, we need to calculate the sales tax, which is 6% of the original cost of the tickets.
The sales tax would be 0.06 * $12 * 2 = $1.44.
Finally, we can calculate the total cost by adding the original cost of the tickets, the sales tax, and subtracting the discount amount.
The total cost would be $12 * 2 + $1.44 - $12 = $13.44.

Final answer:
The number that is 20% larger when read from left to right than when read from right to left is 24.
Explanation:
The question asks for a two-digit number which is 20% larger when read from left to right than it is when read from right to left. Let's denote the digit in the tens place as 'a' and the one in the units place as 'b', then the two-digit number can be written as 10*a + b. When reversed, this becomes 10*b + a.
According to the question, 10*a + b is 20% (or 1.2 times) greater than 10*b + a. So, we can set up the following equation: 1.2(10*b + a) = 10*a + b.
When you solve this equation, the solution is a = 2 and b = 4, so the number the question is asking for is 24

Answers
Final answer:
The probability of 3 successes in 5 trials is represented by '5C3P(S)³P(F)²'. This equation reflects the combination of possible successful events, multiplied by the probability of success raised to the number of successes, and the probability of failure raised to the number of failures.
Explanation:
The correct answer is d. 5C3P(S)³P(F)².
Probability of success in binomial problems is given by the equation P(S) = nCr * (p)ⁿ * (q)ⁿ-r where n is the number of trials, r is the number of successful trials, p is the probability of success, and q is the probability of failure (1-p). In this case, there are 5 trials and 3 successes, so your p to the power of 3 (P(S)³) represents the probability of success and the your q to the power 2 (P(F)²) represents the probability of failure. The 5C3 in front is a combination which shows how many ways 3 successes can occur in 5 trials.
