Step-by-step explanation:
$1170
Given: 6kg rice costs $540
Find: cost of 13kg rice
13 kg rice x ($540 / 6 kg rice)
Units kg rice crosses out and you’re left with $ for units.
(13 x 540) / 6 = $1170
CHECK
13kg rice /6 kg rice = 2.17 bags to make 13kg rice
2.17 bags of 6 kg rice = $1170
So the answer is correct.
Opposite sides are equal.

The temperature at the end of the day is 2 degrees
Step-by-step explanation:
Here, we are interested in calculating the temperature at the end of the day.
In the question, we are told that at the beginning of the day, temperature was -14 degrees.
But throughout the day, the temperature increased by 16 degrees;
Thus, the temperature at the end of the day = -14 degrees + 16 degrees = 2 degrees
