Answer:
Step-by-step explanation:
We are given that
We have to factorize the given expression.
Pair up the terms
Now, taking common factor
Taking common (x+1)
Now, we get
This is required factors of given expression.
Answer:
Its B.
Step-by-step explanation:
It said so.
Plane #1 speed: x mph
Plane #2 speed: (x+30) mph
time = time becomes
170 mi 185 mi
---------- = --------------
x x+30
Solving for x, the speed of the slower plane, we get
170x + 5100 = 185 x
5100
Then 15x = 5100, and x = ---------- (mi/hr) = 340 mph
15
The slower plane flies at 340 mph, and the faster one at 370 mph.
Write 0.055 as
0.055
1
Multiply both the numerator and denominator by 10 for each digit after the decimal point.
0.055
1
The factors of 55 are: 1 5 11 55
The factors of 1000 are: 1 2 4 5 8 10 20 25 40 50 100 125 200 250 500 1000
The Greatest Common Factor (GCF) for both 55 and 1000 is: 5
Now to reduce the fraction we divide both the numerator and denominator by the GCF value.
=
0.055 x 1000
1 x 1000
=
55
1000
In order to reduce the fraction find the Greatest Common Factor (GCF) for 55 and 1000. Keep in mind a factor is just a number that divides into another number without any remainder.
Answer ( 55/1000
= 11/200)
