Answer:
A parallelogram is a quadrilateral with no axis of line symmetry.
Answer:
(- 1, - 2 )
Step-by-step explanation:
Given the 2 equations
x - 3y = 5 → (1)
5x - 2y = - 1 → (2)
Rearrange (1) expressing x in terms of y by adding 3y to both sides
x = 5 + 3y → (3)
Substitute x = 5 + 3y in (2)
5(5 + 3y) - 2y = - 1 ← distribute left side
25 + 15y - 2y = - 1
25 + 13y = - 1 ( subtract 25 from both sides )
13y = - 26 ( divide both sides by 13 )
y = - 2
Substitute y = - 2 in (3) for corresponding value of x
x = 5 + (3 × - 2) = 5 - 6 = - 1
Solution is (- 1, - 2 )

Answer:
36.88
Step-by-step explanation:
6.1 + 6.3 = 12.4
3.2 x 12.4 = 39.68
39.68 - 2.8 = 36.88
If a plane flies an average of 325 miles per hour, to find out 7 hours you will need to times 325 by 7.
325 x 7 = 2275.
therefore the flight for 7 hours was 2275 miles.
