Answer:

Burger Calories Individual: 450

Fry Calories Indicidual: 280

Step-by-step explanation:

First, since there are 2 burgers and each burger has 170 more calories, we will subtract 170 + 170.

170 + 170 = 340.

1740 - 340 = 1400 ( this makes it good for the next part )

Since we have 2 burgers and 3 fries, that will be 5 in total.

All we will have to do is divide 1400 by 5 to get our answer.

1400 ÷ 5 = 280.

Now we know that each of the fries had 280 calories.

280 + 170 = 450 ( add 170 because the instructions say the burger had 170 calories more. )

Therefore, the burgers each had 450 calories and the fries each had 280.

5. Keisha makes $ 135 selling items at a concession stand. She sold an equal number of T-shirts and keychains. The T-shirt costs

exis [7]

Answer:

$108

Step-by-step explanation:

Let n be the cost of a keychain, then the cost of a T-Shirt would be 4n. We can use this to set up an equation...

4n+n=135

Combine like terms

5n=135

Divide both sides by 5

n=27

Now we need to find how much she made from selling T-Shirts...

4n=4(27)=$108

Step-by-step explanation:

The correct question is

At the movie theater child admission is $6.30 an adult admission is $9.60 on Wednesday 172 tickets were sold for a total sales of $1403.70 How many child tickets and adult tickets were sold that day?

Let

x ----> number of child tickets sold

y ----> number of adult tickets sold

we know that

$x+y=172$ ----> equation A

$6.30x+9.60y=1,403.70$ -----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both lines

Using a graphing tool

The intersection point is (75,97)

see the attached figure

therefore

The number of child tickets sold was 75 and the number of adult tickets sold was 97

The diagonal of the rectangle is 15 cm and one of its sides is 9 cm. find the area of the rectangle.

Tems11 [23]

The area of the rectangle is 108 square centimeters.

Given Information

The following information has been given in the question,

Length of the diagonal of the rectangle, l = 15 cm

Length of one of the sides of the rectangle, a = 9 cm

Let the other side of the rectangle be b.

Finding the Other Side of the Rectangle

According to Pythagoras Theorem,

(hypotenuse)² = (base)² + (perpendicular)²

Applying this theorem in the right-angle triangle formed by the diagonal and 9cm side of the rectangle, we get,

l² = a² + b² [∵ The diagonal makes the hypotenuse]

(15)² = (9)² + b²

b² = (15)² - (9)²

b² = 225 - 81

b² = 144

b = √144

b = 12 cm

Calculating the Area of the Rectangle

Area of the rectangle, A = a × b

A = 9 × 12

A = 108 cm²
