Answer:

1/26

Step-by-step explanation:

-4/13 is equivalent to -8/26. Since 9/26 and -8/26 have the same denominator, you can add together the numerator to get the numerator of the final answer. 9-8 is 1, so your answer is 1/26.

You were billed $17.60 for water usage at a rate of $0.55 per gallon. Three choices are correct ways to calculate the the number
nalin [4]

We know that total bill = rate per gallon times numbers of gallons used

So 17.60 = 0.55 times g

which get match to option (a) this is correct .

Now if we divide both sides by 0.55 we would be getting :

17.60 / 0.55 = g which is slightly different than option (b) ( because it is 55 in option b but actually it should be 0.55) so this one is incorrect .

let us now come back to option (a) 17.6 = 0.55 g

if flip the sides it becomes 0.55g = 17.6 which is same as option c option c is also correct .

Let us now divide both sides of option a by g^2 which makes it

17.6/ g^2 = 0.55 /g or 0.55/g = 17.6 /g^2 which matches only left side of option d but not right side of it so this is also not a correct option

Answer : only (a) and c are correct answer .

The agent will receive P55,000 in commission.

The amount of commission cannot be more than the value of the sale. It is generally a small fraction of the sale value. Here, it is 1/10.
