Solve The System Of Linear Equations Using Multiplication.- 4x + 3y95x - 2y29The Solution Is

Answers

Answer 1

Answer:

(15,23)

Step-by-step explanation:

-4x+3y=9

5x-2y=29

Let's multiply the first equation by 2 and the second equation by 3, in order to have the same coefficient on y.

-8x+6y=18

15x-6y=87

Add these two equations together to eliminate y.

7x=105

x=15

Now, plug in x, to find y.

5(15)-2y=29

75-2y=29

-2y=-46

y=23

what is the value of x and y?

Answers

Answer:

The right answer is x = 8, y = 40.

Step-by-step explanation:

Since this triangle is isosceles we know that...

∠ACB = ∠ABC

40° = (5x)°

40 = 5x

x = 40 / 5

x = 8

We also know that the sum of all angles inside the triangle is equal to 180°, therefore...

∠BAC = 180° - ∠ACB - ∠ABC

(2y + 20)° = 180° - 40° - 40°

2y + 20 = 100

2y = 100 - 20

2y = 80

y = 80 / 2

y = 40

From this, we know that the right answer is x = 8, y = 40.

What is the approximate area of a circle with a diameter of 50 centimeters? Use π = 3.14 87.9 square centimeters 379.9 square centimeters 1962.5 square centimeters 4923.5 square centimeters

Answers

Answer:

144πfeets² ; 339.6 cm² ; 2461.8 cm² ; 1962.5 square centimeters

Step-by-step explanation:

Area of a circle, A = πr²

1.)

with a Radius of 12 feets

A = π * 12² = 144πfeets²

2.)

Approximate area :

3.14 * 10.4² = 339.6224 feet²

3.)

with a Radius of 28 cm

A = 3.14 * 28² = 2461.76cm²= 2461.8 cm²

4.

Diameter = 50 cm ; Radius = 50/2 = 25

with a Radius of 25 centimeter

A = 3.14 * 25² = 1962.5 cm²

A group of friends wants to go to the amusement park. They have $243.25 to spend on parking and admission. Parking is $15.75, and tickets cost $22.75 per person, including tax. How many people can go to the amusement park?

Answers

Answer: 10 people

Step-by-step explanation:

Parking needs to be paid for but if all friends are going together, they need to only pay once for parking.

The amount spent on just tickets is therefore:

= 243.25 - 15.75

= $227.50.

If $227.50 was for tickets alone, the number of tickets they could buy is:

= Total amount left/ Price of tickets

= 227.50 / 22.75

= 10 people

The length and width of a rectangle are 1/6 inches and 3/8 inches. What is the perimeter (in inches) of the rectangle?

Answers

Answer:

1 1/12inches

Step-by-step explanation:

Given

Length = 1/6 inches

Width = 3/8 inches

Perimeter of the rectangle = 2 (Length + Width)

substitute

P = 2(1/6 + 3/8)

P = 2(4+9/24)

P=  2(13/24)

P = 26/24

P = 1 2/24

P = 1 1/12inches

hence the perimeter of the triangle is 1 1/12inches

Find the slope of the line using the two given points.

(0, -2) and (3, 4)

Answers

Answer:

m = 2

Step-by-step explanation:

Using the slope formula, we can find the slope of two points:

        y2 - y1

m = --------------

        x2 - x1

The slope is the same thing as change in y over change in x. Now, plugging in the points (0, -2) and (3, 4):

       4 - (-2)       4 + 2     6

m = -----------  =  ------- = ------  =  2

        3 - 0            3         3

So the slope is 2.
