Answer:
After 7 hours Tevin will catch Enrique
Step-by-step explanation:
We have given speed of Enrique is 20 mph
Tevin left traveling after 2 hours of Enrique
Speed of Tevin is 28 mph
When Tevin catches Enrique will cover same distance
Let Enrique is traveling for t hours
Then Tevin will travel for t-2 hours
We know that distance = speed × time
So
t = 7 hours
So after 7 hours Tevin will catch Enrique
$75 dollars divided by $3.40 per gallon ≈ 22.0588 gallons
Answer:
0.04
Step-by-step explanation:
12^(-x) = 5 (taking log on both sides)
log [ 12^(-x)] = log 5
-x log 12 = log 5
-x = log 5 / log 12
x = - (log 5/log12)
x = -0.6477
12^(2x)
= 12^[2(-0.6477)]
= 12 ^ (-1.295)
= 0.04
Answer:
Age of Jacob is 10 years.
Step-by-step explanation:
Let the age of Jacob = x years and age of Kinsley = y years
Then by first statement " Kinsley's age is 7 years less than twice of Jacob's age"
y = 2x - 7
By second statement " Kensley is 13 years old "
y = 3 years
By putting y = 13 years in the equation
13 = 2x - 7
2x = 13 + 7
2x = 20
x = = 10 years
Therefore, age of Jacob is 10 years.
