Answer:
2x - 6 = 4
Step-by-step explanation:
Firstly, let's assume the number is x
Then, twice the number is 2 times x = 2x
6 less than twice the number is four
2x - 6 = 4
2x - 6 + 6 = 4 + 6
2x = 10
2x/2 = 10/2
x = 5
By 91 dollars
because 22.75 times 4 is 91
This is how it would work to find answer
You divide 225 by 45 and the answer you would get is 5 so
It will take 5h for the train to travel
hope this helps
20 because there are many more
6.9 = 6.9 / 1
Numerator = 6.9 × 10 = 69
Denominator = 1 × 10 = 10
Numerator / Denominator = 69 / 10
Simplifying our fraction
= 69/10
= 69/10
= 6 9/10
