Answer:
Step-by-step explanation:
1st way:
Solve directly
6p=0.6(5p+15)
Open bracket
6p = 3p + 9
Collecting like terms
6p - 3p = 9
3p = 9
Dividing by 3
p = 9/3
p = 3
2nd way:
6p=0.6(5p+15)
Convert the decimal to fraction
6p= 6/10(5p+15)
6p= 3/5(5p+15)
6p= 3/5(5p) +3/5(15)
6p = 3p + 9
Collecting like terms
6p - 3p = 9
3p = 9
Dividing by 3
p = 9/3
p = 3
For this case, the first thing we must take into account is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Substituting values we have:
Trip 1:
50 = v * t1
We cleared t1:
t2 = (50) * (1 / v)
Trip 2:
300 = (3 * v) * t2
We cleared t2:
t2 = (300/3) * (1 / v)
t2 = (100) * (1 / v)
Rewriting:
t2 = 2 (50) * (1 / v)
t2 = 2 * t1
Answer:
His new time compared with the old time was:
Twice the old time.
t2 = 2 * t1.
Answer:
Square root of 16.
Step-by-step explanation:
Square root 16 = 4 which is rational.
All the rest have an irrational square root.
40/48 divides by 8/8= 5/6 is your answer
