Answer:
Jason is 14 year old.
Step-by-step explanation:
Given: Joe, John and Jason are each a year apart in age.
Sum of their age is 39.
Lets assume the age of Joe be x
∴ Age of Jahn will be 
And age of Jason will be 
Now, putting up an equation for the sum of their age.
∴ 
Opening the parenthesis.
⇒
⇒
Subtracting both side by 3
⇒ 
Dividing both side by 3
⇒
∴ 
Hence, Joe is 12 year old.
Next subtituting the value of x to find age of Jason and John.
Jason= 
∴Jason= 14 years.
John age= 
∴ John Age= 13 years.
Hence, Jason is 14 year of age.
It is less than 20 km, because 20 km is equal to 20000 m
Answer:
A statement that helps to condition
Step-by-step explanation:
We have the first equation:
-10x + 5y = zero
we can divide all terms by 5 to get:
-2x + y = zero
This means that:
y = 2x .................> equation I
We now will look at the second equation:
<span>-4x-6y=54
</span>we will substitute with equation I in this equation to get:
<span>-4x-6(2x)=54
-4x - 12x = 54
-16x = 54
x = -3.375
Substitute with the value of x in equation I to get y as follows:
y = 2(3.375) = -6.75
Therefore, for the given system of equations:
x = -3.375
y = -6.75</span>
