With what exactly in what studies i'm a junior in high school so I should be able to help you
He ran 4 miles per hour for one hour, which means he ran 4 miles.
He cycled 6 miles at 12 miles per hour, which means he cycled for one half an hour.
His total miles was 4 + 6 = 10 total miles.
His total time was 1 hour + one half an hour = 1.5 hours.
His average speed is total distance divided by total time:
10 / 1.5 = 6 2/3 miles per hour.
2*(n-55)=3*(n+8.8)
2n-110=3n+26.4
-136.4=n
Answer:
<u>Filling in the blanks:</u>
- 1. Opposite
- 2. C
- 3. Opposite
<u>Factoring the polynomial:</u>
- x² + 11x - 26 =
- x² + 13x - 2x - 26 =
- x(x + 13) - 2(x + 13) =
- (x - 2)(x + 13)
