Mile in one minute. Therefore, at this rate, Kyle runs one mile in 10 minutes. It follows that it would take Kyle 3 × 10 = 30 minutes to run 3 miles.
Answer:
Step-by-step explanation:
90 times 3 = 270
9x-3 + 6x + 48 = 270
add like terms, 48-3 = 45
9x + 6x + 45 = 270
subtract 45 both sides and add like terms again
15x = 225
divide 15 on both sides
x = 15
Answer:
B. She subtracted the end time from the start time and
D. She did not account for a.m. and p.m. in the start and end times.
Step-by-step explanation:
The school started at 8:05 a.m. and ended at 2:40 p.m.
And the length of the school day is calculated by Erica and it is shown in the attached photo.
See the attached photo.
Erica has done two errors which are
B. She subtracted the end time from the start time and
D. She did not account for a.m. and p.m. in the start and end times. (Answer)
A=x(1+r/n)^nt
21150=x(1+0.032/12)^84
21150=x(1+0.0026666)^84
21150=x(1.002666666)^84
21150=x(1.25069809)
21150/1.25069809=x
16910.56=x
Hope this helps!
Answer:
{(-14,9),(4,-7),(-8,6)}.
Step-by-step explanation:
To find the inverse you just swap x and y.
So if (a,b) is a point on the relation then (b,a) is on it's inverse.
So the inverse of {(9, –14), (–7, 4), (6, –8)} is:
{(-14,9),(4,-7),(-8,6)}.
