Using scientific notation, it is found that:
67 ns = 
s
<h3>What is scientific notation?</h3>
A number in scientific notation is given by:
With the base being 
.
In this problem, the amount is of 67 ns.
Each ns has 
seconds, hence:
We want the base between 1 and 10(exclusive), hence, we move the decimal digit one digit to the left and add one to the exponent, and the representation is:
67 ns = s

We know that 1 ton=2000 lbs
we have 2 tons=4,000 lbs
each crate holds 10 lbs of sugar
4,000/10=400 crates
Answer:
Substitution method can be used
Step-by-step explanation:
Given the system of equations
y = 2x-1 ....1
-12x + 3y = 9 ....2
The best method to use id the substitution method
Substitute equation 1 into 2;
From 2;
-12x + 3y = 9
-4x + y = 3
-4x + 2x-1 = 3
-2x -1 = 3
-2x = 3+1
-2X = 4
x = -4/2
x = -2
Substitute x = -2 into 1
y = 2x - 1
y = 2(-2)-1
y = -4-1
y = -5
Hence the solution to the system of equation is (-2, -5)

0.17/30 = x/450 <em>Use proportion</em>
76.50 = 30x <em>Cross multiply</em>
2.55 = x <em>Divide 30 both sides</em>
