Answer:

  see the attached

Step-by-step explanation:

Alternate interior/exterior angles are congruent where a transversal crosses parallel lines. The angles are congruent if and only if the lines are parallel.

Same-side interior/exterior angles are supplementary where a transversal crosses parallel lines. The angles are supplementary if and only if the lines are parallel.

Linear angles are supplementary, a fact that can be combined with either of the above to derive more angle relationships.

The solution to the system of equations are (2, 5).

Solution:

The system of equations are

x + y = 7 – – – – (1)

2x – y = –1 – – – – (2)

To find x from equation (1):

x + y = 7

Subtract y from both sides of the equation, we get

⇒ x + y – y = 7 – y

⇒ x = 7 – y – – – (3)

Substitute (3) in (2) we get,

2(7 – y) – y = –1

14 – 2y – y = –1

14 – 3y = –1

Subtract 14 from both sides,

–3y = –15

Divide by –5 on both sides,

y = 5

Substitute y = 5 in equation (3)

x = 7 – 5

x = 2

The solution to the system of equations are (2, 5).

Kay [80]

Answer:

1, 000

Step-by-step explanation:

2% · <em>x</em> = 20

0.02 · <em>x</em> = 20

20/0.02 = <em>x</em>

<em>x</em> = 1000

Double-Check:

1000 · 0.02 = 20

The area of a door is 3024 square inches. If the length of the door is 48 inches longer than the width of the door, what is the
borishaifa [10]

Answer:

The width of the door is 36 inches

Step-by-step explanation:

The given parameters are;

The given area of the door = 3024 in.²

The length of the door = 48 + The width of the door

Let W represent the width of the door

Therefore, we have;

The length of the door = 48 + W

The area of the door = The length of the door × The width of the door

∴ By substitution, the area of the door = 3024 = W × (48 + W)

3024 = W × (48 + W) = 48·W + W²

48·W + W² = 3024

∴ 48·W + W² - 3024 = 0

Rearranging, we get;

W² + 48·W - 3024 = 0

By trial and error, we have;

(W + 84)×(W - 36) = 0

Therefore, given that the width of the door is a natural number, we have;

The width of the door, W = 36 inches
