Answer: -4

Reasoning: so first you need to subtract the 7 from the 9 to get -2. Then you square it to get 4 because a negative 2 times -2 is 4. Then you multiply the 4 by the 2 to get 8. You can simplify the -10/5 to -1/2 and multiply that by the 8 to get -8/2 which simplified out to -4.


I hope that helps.

A group of hikers walked 2 3/5 miles along a hiking trail. Another group of hikers walked 1/2 that distance with the first group
inn [45]

Answer:

1 \frac{3}{10} miles.

Step-by-step explanation:

Given that a group of hikers walked 2 \frac{3}{5} miles along a hiking trail. Another group of hikers walked \frac{1}{2} that distance with the first group before turning off onto another trail. Now we need to find about how many miles did the two groups of hikers walk with each other.

To find that we just need to find half of 2 \frac{3}{5}

=\frac{1}{2}\left(2\frac{3}{5}\right)

=\frac{1}{2}\left(\frac{13}{5}\right)

=\frac{1*13}{2*5}

=\frac{13}{10}

=1 \frac{3}{10}

Hence final answer is 1 \frac{3}{10} miles.
