Answer:
x = -30
y = -20
Step-by-step explanation:
x - 12y = 210..... (I)
x - 6y = 90..... (II)
Subtract equation (II) from (I)
- 12y - (-6y) = 210 - 90
-12y + 6y = 120
-6y = 120
Divide through by -6y
Therefore, y = -20
Substitute y = -20 in equation (II)
x -6 (-20) = 90
x + 120 = 90
x = 90 - 120
x = -30

AC # A'B'
Step-by-step explanation:
While solving the above problem one must keep in mind that
- Reflection along Y-axis would just make the rectangle upside down at the same distance from X-axis in the down direction.
Thus, from the figure it becomes clear that
- AB ∦ B’D’
- CD║A’B’
- BD ∦ C’D’
Only statement that comes out true is the third statement which states that AC is not parallel to A’B’
Since the diagonal of a rectangle can not be parallel to one of its side (though the side in question is side of the same rectangle reflected in y axis)
Answer:
it is 25
Step-by-step explanation:
if 5 min is 1/2 mile, then do 5 1/2 miles.
5=1/2 mi
10=1 mi
15=1 1/2 mi
20=2 mi
25=2 1/2 mi
have a good day!
