3 + 4/6 - 1/6

3 + 3/6

3½

3 1/2

Step-by-step explanation:

-3 1/6+6 2/3

We need to get a common denominator of 6

-3 1/6 + 6 2/3 *2/2

-3 1/6 + 6 4/6

Since the signs are different, we subtract and take the sign of the larger number

6 4/6 - 3 1/6 = 3 3/6 = 3 1/2

The sign of the larger number was positive so the answer is positive

3 1/2

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s
