We can first look into the properties of parallelogram,you can also take reference from the figure above:

-Opposite sides are parallel and are congruent.
-Opposite angles are congruent.
-The diagonals bisect each other.

We can then look into the answer:

A.Opposite angles are congurent.
-This is an correct statement.

B.Diagonals are congruent.
-This is incorrect,although they bisect each other,they do not have the same length.

C.The diagonals are peroendicular to each other.
-This is incorrect as well,not every parallelogram has the angle of 90° in the place where the diagonals bisect each others.

D.The area is equal to the product of two adjacent side-this is not true,to find the area,it have to be base×height.

Therefore the answer is A.

Hope it helps!

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adult
amid [387]

Answer:

Number of children = 386

Number of adults = 287

Step-by-step explanation:

Let

x = number of children

y = number of adults

x + y = 673 (1)

1.75x + 2y = 1249.50 (2)

From (1)

x = 673 - y

Substitute x = 673 - y into (2)

1.75x + 2y = 1249.50

1.75(673 - y) + 2y = 1249.50

1177.75 - 1.75y + 2y = 1249.50

- 1.75y + 2y = 1249.50 - 1177.75

0.25y = 71.75

y = 71.75/0.25

y = 287

Substitute y = 287 into (1)

x + y = 673

x + 287 = 673

x = 673 - 287

x = 386

Number of children = 386

Number of adults = 287

Answer:

y = - \frac{1}{3} x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (3, 0) ← 2 points on the line

m = \frac{0-1}{3-0} = - \frac{1}{3}

Note the line crosses the y- axis at (0, 1) ⇒ c = 1

y = - \frac{1}{3} x + 1 ← equation of line
