Mathematics
1 answer:
grin007 [14]3 years ago
7 0

Answer:

No solutions.

Step-by-step explanation:

-2x -  y = 1

-4x - 2y = -1 Multiply the first equation By  -2:

4x + 2y = -2  Adding:

0 = -3

which is absurd so there are no solutions.

Question: A square with sides of length 5 is positioned inside a square with sides of length 7. What is the total area between t
Sergio [31]

Answer:

The total area between the squares is of 24 units squared.

Step-by-step explanation:

Area of a square:

The area of a square of side length l is given by:

A = l^2

Area between figures:

The area between two figures is the area of the larger figure subtracted by the area of the smaller figure.

Larger square:

Square with side of length 7. So

A_l = 7^2 = 49

Smaller square:

Square with side of length 5. So

A_s = 5^2 = 25

What is the total area between the squares? ​

T = A_l - A_s = 49 - 25 = 24

The total area between the squares is of 24 units squared.

Find the value of x in each case. Give reasons to justify your solutions! NEEDED ASAP
Mashcka [7]

Answer:

<em>( x = 17° )</em>

Step-by-step explanation:

Consider the following steps;

m< ZYW = 2x - Given,\\m< YXW = ( 3x - 5 ) - Given,\\m< XYW = 90 - Given,\\\\m< YXW + m< XYW + m< YWX = 180 - Sum of Angles in Triangle,\\( 3x - 5 ) + 90 + m< YWX = 180,\\3x - 5 + 90 + m< YWX = 180,\\3x - 5 + m< YWX = 90,\\m< YWX = 90 - 3x - 5,\\m< YWX = 85 - 3x,\\\\m< ZYW = m< YWX - Alternate Interior Angles,\\2x = 85 - 3x,\\5x = 85,\\Conclusion ; ( x = 17 degrees )

<em>Solution ; ( x = 17° )</em>
