Step-by-step explanation:
Lets quickly run through the prime numbers and see what it is not divisible by
39 is not divisible by 2
39 IS divisible by 3
So lets stop right here.
What is 39 divided by 3? 13 !
And 13 is a prime number too!

Answer:
50,000 in scientific notation is 5 x 10^4
Step-by-step explanation:
10^4 = 10,000 x 5 = 50,000
The computation of the equation shows.that x is -4 and y is 0.6.
<h3>How to calculate the value?</h3>
4x + 5y = -1
-5x - 8y = 10
The value of x and y will be calculated thus:
-5 × (4x + 5y = -1)
4 × -(5x - 8y = 10)
-20x - 25y = 5
-20x -32y = 40
Add the equation
57y = 45
y = 45/75 = 0.6
Since 4x + 5y = -1
4x + 5(0.6) = -1
4x + 3 = -1
x = -1 - 3
x = -4
