Gina visited the aquarium with some of her cousins, aunts, and uncles. The group bought 20 admission tickets for $340. Adult tickets cost $20, and children’s tickets cost $15. How many adult tickets and how many children tickets did the group buy?
Write a system of equations.
Answer:
Look at the attachment
Step-by-step explanation:
There are 12 children tickets did the group buy.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The group bought 20 admission tickets for $340.
And, Adult tickets cost $20, and children’s tickets cost $15.
Let number of children = x
And, Number of adult = y
Hence, We get;
The system of equations are,
x + y = 20
y = 20 - x .. (i)
And, 15x + 20y = 340
3x + 4y = 68 .. (ii)
Substitute the value of y from (i) in (ii);
3x + 4(20 - x) = 68
3x + 80 - 4x = 68
80 - 68 = x
x = 12
Thus, There are 12 children tickets did the group buy.

Answer:
For the 1st one the answer is y = 5x + 150 and the second one is equal to y = -25x + 200.
Step-by-step explanation:
The first one would not be 30 because you're not finding the x value, just the equation. The second one you start with 200 hundred so you're adding 200 and since you're spending money every month it means subtracting. And the only equation that makes sense is y = -25x + 200

Estimate 79% of 82 show work
Answer:96.34%
Solution for 79 is what percent of 82:
79: 82*100 =
(79*100): 82 =
7900: 82 = 96.34%
Answer:
64.72
79 percent *82 =
(79:100)*82 =
(79*82):100 =
6478:100 = 64.78
Now we have: 79 percent of 82 = 64.78
Explain how to solve the equation and how to check the solution.
40 = 8y
there the answers-
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.
equations by using inverse operations, including squares, square roots, cubes, ... A pair of inverse operations is defined as two operations that will be ... The following examples summarize how to undo these operations using their ... x is divided by 2, so we multiply by 2 on both sides. 2. 8 2. 2 x. ∙ = ∙. Solution: 16. explanation:

A cake recipe requires flour and sugar in a ratio of 4 to 3. Which table has been generated using this ratio?
Answer:
The third table
Step-by-step explanation:
A ratio is a relationship that illustrates how many times one number contains another. For example, the ratio of 4:3 means there is 4 cups of flour for every 3 cups of sugar. The third table is the only one that increases proportionate to the ratio. This can be seen because when 4 is multiplied by 3 to get 12, so is 3 to get 9. This pattern continues, with both amounts being multiplied by the same number.
William gets a student loan to pay for his college tuition. He borrowed $2,500 for 10 years at an interest rate of
8%. How much will William pay in interest on this loan?
Answer:
2897.31
Step-by-step explanation:
I'm going to assume two things
The interest rate is compoudning annually
There is only one payment (at the end of the 10 years)
To find the amount of interest paid on this loan we first need to calculate the future value (or accumulated value)
FV=PV(1+i)^n
Plug in our numbers
2500(1+.08)^10
Run this through a calcuatlor and get 5,397.31
This is the future value and the question is asking for the interest paid which is just the FV-PV
Which means we have
5,397.31-2500
our answer is 2897.31
