The equation looks like this right now: 4/5x=2/5. In order to solve for x, you need to divide both sides by 4/5. When dividing fractions, you need to remember the rule KCF (keep, change, flip) So, you will keep the first fraction, change the division sign to a multiplication sign, and flip the last fraction. Now you have 2/5*5/4. When you do that, you get 10/20. Simplify it, and you end up with 1/2, and that is your answer. I hope that helped! :)
Answer:
A. $6
Step-by-step explanation:
We are given the table representing the number of days and the total charges in dollars.
So, the rate of change of the amount is given by, 
The linear equation representing the situation is,
Total charges = Fee per days + Fixed amount.
i.e. Total charges, y = Rate multiplied by x + Fixed amount (c)
So, substituting the rate and the point (0,6), we get,
6 = 10 × 0 + c
i.e. c = 10
Thus, the equation is,
Total charges, y = Rate multiplied by x + Fixed amount (c)
i.e. y = 10x + 6
Hence, the fixed amount charged is $6.
So, option A is correct.
