Answer:
I attached a picture below of what the lines of symmetry are.
Answer:
n = 13
Step-by-step explanation:
The sum of the measures of the interior angles of an n-sided polygon is
(n - 2)180
Set (n - 2)180 equal to 1980 and solve for n.
(n - 2)180 = 1980
Divide both sides by 180.
n - 2 = 11
Add 2 to both sides.
n = 13
Y = -5x -5
To check, we can insert 0 for y and -1 for x
0 ? (-5X-1) - 5
0 ? 5 - 5
0 = 0
So yes, the equation is correct
Answer:
Nephew receive 1500.00
Older niece receive 1000.00
Younger niece receive 500.00
Step-by-step explanation:
Let assume a variable x,y,z for the niece, older niece and the nephew respectively.
Y= 2x (Twice the younger niece)
Z= x + y. (Sum of the two nieces)
Since y = 2x
Z = x+2x
Z= 3x
Therefore:
X = 1x
Y = 2x
Z = 3x
So the will will be shared among them in the ratio
Nephew : older niece : younger niece
3 : 2 : 1
Nephew. 3/6 x 3000 = 1500.00
Older niece 2/6 x 3000 = 1000.00
Younger niece 1/6 x 3000 = 500.00
