Answer:

the "acceleration" is -15m/s (it's negative because it is slowing down, not speeding up[it might just be a positive 15m/s if it is called deceleration and not acceleration])

Step-by-step explanation:

30m/s (starting speed)/2 (the number of seconds it took to stop from 30m/s

I don’t understand! help!
Ksju [112]

Answer:

x = 8

Step-by-step explanation:

These angles are alternate interior angles and m is parallel to n, so they're congruent, meaning that they're equal!

So we can make our equation:

6x - 2 = 46

6x = 48

x = 8

Hope this helps!

If the measure of an angle is p is three times less than twice the measure of angle q and angle p and angle q are supplementary
Marizza181 [45]
60 * 3 = 180 and 90 * 2 = 180
if they are supplementary angles than they equal 180 together. 
angle p is three times less than twice the measure of angle q so that means 180/3 = angle p and 180/2 = angle q. 
Angle q is 90 and twice that is 180 and Angle p is 60 and three times that is 180
so 60 is three times less than twice the measure of 90.
60 three times is 180 and 90 twice is 180 which means 3p = 2q and you have 180 because they are supplementary angles so you have really 180/3 = p and 180/2 = q
The answer is p = 60 and q = 90
