On a saturday, the ratio of the amount of water used by household a to the amount of water use by household b was 13 : 5. household a used 260 gallons of water for that day. find the total amount of water used by the two household on that saturday.

the total amount of water used by the two households on that Saturday is 360 gallons

Step-by-step explanation:

Let x represent the total amount of water used by the two households on that Saturday. On that Saturday, the ratio of the amount of water used by household A to the amount of water use by household B was 13 : 5. The total ratio is 13 + 5 = 18

The amount of water used by household A would be

13/18 × total amount of water.

The amount of water used by household B would be

5/18 × total amount of water.

Since household A used 260 gallons of water for that day, it means that

13/18 × x = 260

13x = 260×18 = 4680

x = 4680/13 = 360

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
