Answer:
2(a - 2b)
Step-by-step explanation:
2 is a common factor of 2a - 4b. The a's and b's cannot be part of the common factor.
2(a - 2b) is the answer.
Notice that both sides of the minus sign are effected by the two being taken out.
well -2(-1/4) is .5
so -2, .5,(multiply each by -1/4)
-2, 0.5, -0.125, 0.03125
Answer:
47
Step-by-step explanation:
Coastline of Alaska is 64,000 miles
Coastline of Florida is 1350 miles
To calculate the number of times, we need to compute the ratio of the two coastlines. The ratio is given by \[\frac{64000}{1350}\]
The value of this ratio is 47.407
Rounding the value to the nearest integer , the ratio is 47.
So the state of Alaska's coastline is 47 times the coastline of Florida.
