GCF is the greatest common factor. its the value of the factors that are common to both the numbers being compared. In other words the product of the factors that are common to both numbers or the greatest factor common to both numbers.
factors of x⁴ = x * x * x * x = (x * x * x) * x
factors of x³ = x * x * x = (x * x * x)
factors common to both are (x * x * x) Therefore GCF is x³
Let n be Fritzs' car speed, and n+12 be the speed of the train. Then:
1/2 (n)=1/3 (n+12)
2n+24=3n
n=24 mph
n+12=36 mph
Fritz travels 12 miles to work.
30 min @24mph=12 miles
20 min @36mph=12 miles

Answer:
x=1
Step-by-step explanation:
X+y=70
x-y=30
x=30+y
30+y+y=70
2y=40
y=20
x+20=70
x=50
xy=(50)(20)=1000
Answer:
They drove 150 miles on the 3rd day.
Step-by-step explanation:
Use a ratio to solve:
miles : hours
300 : 6
250 : 5
50 : 1
x : 3
x would be 150 miles
