Answer:

x = 67

y = 32

Step-by-step explanation:

Vertical angles are congruent

that means

52 = x- 15

You want to add 15 in both sides

x = 67, and the other angle measures 52 degrees

Same thing applies to 128 and 4y

4y = 128

y = 32

At a movie theater, the price of two adult tickets and for children ticket is $40 the price of a daughter gets into trouble to g

den301095 [7]

Answer: The price for one adult ticket is $10 and the price for one child ticket is $7.

Step-by-step explanation:

<h3> The correct exercise is: "At a movie theater, the price of 2 adult tickets and 4 children tickets is 48$. The price of 5 adult tickets and 2 child tickets is 64$. What is the price for one adult and one child?"</h3>

Let be "a" the price (in dollars) for one adult ticket and "c" the price (in dollars) for one child ticket.

Set up a System of equations with the data given in the exercise:

$\left \{ {{2a+4c=48} \atop {5a+2c=64}} \right.$

You can use the Elimination method to solve the System of equations:

1. Multiply the second equation by -2.

2. Add the equations.

3. Solve for "a".

Then:

$\left \{ {{2a+4c=48} \atop {-10a-4c=-128}} \right.\\........................\\-8a=-80\\\\a=\frac{-80}{-8}\\\\a=10$

4. Substitute the value of "a" into any original equation.

5. Solve for "c":

$2(10)+4c=48\\\\4c=48-20\\\\c=\frac{28}{4}\\\\c=7$

Explain how you find it

aliina [53]

Answer:

x = 39

Step-by-step explanation:

there is a theorem that states that the midsegment in a trapezoid is equal to the sum of the bases divided by two

so, (36 + 42)/2 = x

36 + 42 = 78

78/2 = 39
