Answer: 30 should be negative
Step-by-step explanation:
when having an equation like that, you must multiply -5 by 3, which equals to -15, then multiply-5 by 6 which then equals to -30. The correct equation should be -5(3+6)= -15+-30= -45
I think this should be correct, hope this helps!
Answer:
Trey lives 384 feet.
Step-by-step explanation:
Let the average rate be represented by s, and the distance by d.
speed =
⇒ distance = speed x time
i.e d = s x t
On his first trip,
d = s x 8
d = 8s ............ 1
on his trip home, the average rate was 16 miles per hour faster, so that;
d = (s + 16) x 6
d = 6s + 96 ............ 2
Equation 1 and 2, we have;
8s = 6s + 96
8s - 6s = 96
2s = 96
s = 48
The average rate is 48 miles per hour.
Thus from equation 1 (also equation 2 can be used),
d = 48 x 8
= 384
Therefore, Trey lives 384 feet from the mountains.
Answer:
0
Step-by-step explanation:
Each loop is of a different size, so we can't rotate the figure some angle x to have it line up with itself (0 < x < 360). Therefore, it doesn't have any rotational symmetry. That rules out choice A and choice C. Point symmetry is the same as saying "rotational symmetry of 180 degrees"
The figure doesn't have any line symmetry either. There is no line we can draw and reflect the figure over to have it match up with itself. That rules out choice B and points to choice D
Answer: D) It has no reflectional symmetry.
