Answer:
10
Step-by-step explanation:
If we plug in any negative number as x, the result will always be greater than 4, which rules out answers A and B
lets try plugging in 4 as x to test answer C:
2(8-4)
2(4)= 8
8 is greater than 4, therefore C is wrong.
Lets try 10 as X (answer D):
2(8-10)
2(-2)
-4
We know that -4 is less than 4, therefore it makes the inequality true! :)

1 hour.
Step-by-step explanation:
You have to do the total distance /total speed together.
You have to do this to ensure that you are counting how fast they are travelling together.
(450 km) / the sum of their speed (240+210)
450/ (240+210)

=1
Answer: 1 Hour.
Answer:
23.12
Step-by-step explanation:
Jordan has entered 3.4 x 6.8 on his calculator.
3.4 x 6.8 = (34/10) x (68/10) = (34 x 68) / (100) = 23.12
Or an easier way would be, observing the two numbers.
In 3.4 , there is one digit after decimal point.
In 6.8 there is one digit after decimal point.
So in their product there should be two digits after the decimal point.
So the answer is <em>23.12</em>
