In which quadrant would point (-4.5, -4.5) be located

Solve the system of equations and choose the correct ordered pair. 3x + 4y = 38 5x - 5y = -30

faust18 [17]

3x + 4y = 38 ( equation 1) ----> ×5 5x - 5y = -30 ( equation 2) ----> ×3 When you multiply eqn 1 by 5 you get, 15x + 20y = 190 And when you multiply eqn 2 by 3, you get, 15x - 15y = -90 Then you solve both equations by subtracting eqn 2 from eqn 1 15x + 20y = 190 15x - 15y = 90 Then 15x - 15x gets cancelled and 20y - (-15y) gives 35y and 190 - (-90) gives 280. So that gives 35y = 280 y = 8 And when you replace y = 8 in any of the two equations, x = 2

1-7x - 7=15 please answer and show how you got answer please

zlopas [31]

Answer:

x=-3

Step-by-step explanation:

1-7x-7=15

We move all terms to the left:

1-7x-7-(15)=0

We add all the numbers together, and all the variables

-7x-21=0

We move all terms containing x to the left, all other terms to the right

-7x=21

x=21/-7

x=-3

A carpenter lays 15 square feet of tile in 1/3 of an hour. How many square feet does the carpenter may per hour?

taurus [48]

Answer:

x=24 square feet per hour

Step-by-step explanation:

You divide 16 by 2 to get how many tiles that are laid in 1/3 of an hour. Then multiply that by 3 to get how many tiles in one whole hour. The answer should be 24.

How would you find the area or perimeter of this shape?

Fittoniya [83]

The perimeter of a given shape implies the sum of all its sides. While the area of a given shape is the total value of space it would cover on a 2-dimensional plane.

The perimeter of the shape is 104 cm.

The area of the shape is 640 $cm^{2}$ .

The perimeter of a given shape implies the sum of all its length of sides., such that the value of each individual side is summed to a total value.

The area of a given shape is the total value of space it would cover on a 2-dimensional plane. The area of shapes depends on the type of shape.

In the given question, the given shape has 12 sides. Some of these sides can sum up to a given length as shown in the diagram.

So that;

perimeter = 2 + 32 + 10 + 10 + 2 + 32 + 8 + 8

= 104 cm

Thus, the perimeter of the shape is 104 cm

ii. The area of the shape = length x width

= 32 x 20

= 640 $cm^{2}$

Therefore, the area of the given shape is 640 $cm^{2}$ .
