One spring day, London noted the time of day and the temperature, in degrees Fahrenheit. Her findings are as follows: At 6 a. m., the temperature was 58° F. For the
next 2 hours, the temperature rose 3° per hour. For the next 6 hours, it rose 1° per
hour. The temperature then stayed steady until 6 p. m. For the next 2 hours, the
temperature dropped 1° per hour. The temperature then dropped steadily until the
temperature was 66° at midnight. On the set of axes below, graph London's data.

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153

step-by-step explanation:

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
