D beacuse a hexangon is like the shape of the circle
29.1 bc the hypotenuse is always the longest side
X+y=1770
9x+4y=14680
x=1770-y
9(1770-y)+4y=14680
15930-9y+4y=14680
-5y=-1250
5y=1250
y=1250/5
y=250
children attended=250
Answer:
<em>x = -2</em>
<em>y = -5</em>
Step-by-step explanation:
<u>Properties of a Parallelogram</u>
- Two pairs of opposite sides are parallel.
- Two pairs of opposite sides are equal in length.
- Two pairs of opposite angles are equal in measure
- The diagonals bisect each other.
- Adjacent angles are supplementary.
- Each diagonal divides the quadrilateral into two congruent triangles.
Each diagonal is divided into two measures expressed with variables. Since diagonals bisect each other:
y + 23 = -4y - 2. And
-2x + 6 = x + 12
Solve the first equation. Adding 4y:
5y + 23 = - 2
Subtracting 23:
5y = -25
Dividing by 5:
y = -5
Solve the second equation. Subtracting x and 6:
-3x = 6
Dividing by -3:
x = -2
Solution:
x = -2
y = -5
Answer:
Associative Property
Step-by-step explanation:
hey! This is an example of the associative property because your are changing where the parentheses are located. Just remember that when using the associative property, you are changing who the values are associating themselves with. PLS MARK BRAINLIEST! Thank you! Hope this helps.
