A. Multiplication is the ONLY function that reverses what division did. If you did 56/-14 = n, then n x -14 should equal 56.
2w+2(10)=30
multioly the 2 and 10
2w+20=30
subtract 20
2w=10
divide by 2
w=5

7 mm x 9mm x 12mm = 756mm
To get this answer you have to multiply 9 and 12 which would be 108. Then you have to divide 108 on both sides to get mm by itself. 756 divided by 108 is 7 which is the answer!
Answer:
25 meters
Step-by-step explanation:
30 km/hr = (30 km/1 hr)*(1000 m/1 km)*(1 hr/60 min)*(1 min/60 sec)
30 km/hr = (30*1000*1*1)/(1*1*60*60) meters per second
30 km/hr = 8.3333333333 m/s (approximate)
----------
The speed or rate is r = 8.3333333333 meters per second approximately, and the time is t = 3 seconds, so,
distance = rate*time
d = r*t
d = 8.3333333333 * 3
d = 24.9999999999
Due to rounding error, the true answer should be d = 25. We can see this if we opted to use the fraction from of 8.3333... instead of the decimal representation which isn't a perfect exact measurement.
