Answer:
Your question but don't know how to solve it like a dog
-3/2
Down 3
Right 2
As an improper fraction it would be -1 1/2
First we find the common difference...to do this we subtract the first term from the second term. -7 - (-1) = -7 + 1 = -6
now we are going to find the 10th term
an = a1 + (n-1)*d <== formula for finding any term in arithmetic series
a1 = 1st term, d = common difference, n = term we want to find
now we sub
a10 = -1 + (10 -1) * -6
a10 = -1 + (9 * -6)
a10 = -1 - 54
a10 = - 55
now we will find the sum
Sn = (n (a1+ an)) / 2 <== formula for finding the sum
S10 = (10(-1 - 55))/2
S10 = (10(-56) / 2
S10 = -560/2
S10 = - 280
so the sum of the first 10 numbers is -280

Answer:
1/2 ft
Step-by-step explanation:
Skylar's speed was ...
(65 ft)/(5 s) = 13 ft/s
Rodrigo's speed was ...
(108 ft)/(8 s) = 13.5 ft/s
Rodrigo traveled farther by (13.5 -13) = 0.5 ft per second.
opposite of a sum property
