Answer:
5.6 x 10^3 (10 to the power of 3)
i.e. 5600 = 5.6 x 10^3 because you have to go back 3 times to get 5.6 *you cannot have a number less than 1 or more than 10*
So the power of 3 is the amount of times you had to move back
Step-by-step explanation:
This is how you write 5600 in standard form!

Answer:
0.75
Step-by-step explanation:
Each 1/4 is a quarter so multiply 0.25*3 which equals 0.75
Factor out the common term 4
-4(2x - y) = 24
Divide both sides by -4
2x-y= - 24/4
Simplify24/4 to 6
2x -y = -6
Subtract 2x from both sides
-y = -6 - 2x
Multiply both sides by -1
y = 6 + 2x
Chris and Jim must replace a <em>total</em> quantity of 17 tyres.
<h3>What is the minimum number of tyres to be replaced?</h3>
In this problem we must use an inequality of the form f(x) ≥ a, where f(x) is the difference between the number of tyres replaced by Jim and the number of tyres replaced by Chris:
(25/20) · x - x ≥ 3
(5/20) · x ≥ 3
x ≥ 12
Then, the <em>minimum</em> number of tyres to be replaced is n = 15 + 12 = 17 tyres.
