Whenever two lines intersect, they form two pairs of vertical angles. Vertical angels have a common vertex, but they are never adjacent angles. Fin, vertical angles are always congruent.
D. You have to since the sign is opened to the left, go right. So, Y>-1.5
It’s to the opposite
Answer:
4x4=4*4=16
7x7=7*7=49
5x5=5*5=25
2.5x2.5=2.5*2.5=6.25
Step-by-step explanation:
Answer:
$25
Step-by-step explanation:
500 mins = $35 (fixed + per minute charge)
1500 mins = $55 (fixed + per minute charge)
If we let per minute charge be "m"
and
let fixed charge be "f"
we can write 2 equations as:
35 = 500m + f
and
55 = 1500m + f
Now,
We re-write both equations in terms of f and equate both expressions:
f = 35 - 500m
and
f = 55 - 1500m
Equating:
35 - 500m = 55 - 1500m
-500m + 1500m = 55 - 35
1000m = 20
m = 20/1000
m = 0.02
Now we find f, what we are looking for:
f = 35 - 500m
f = 35 - 500(0.02)
f = 25
So, the fixed charge is $25
