Answer:

False

Step-by-step explanation:

Let's check whether (-3, 4) satisfies the given inequality 2x + y > -2.

Replacing x with -3 and y with 4 yields                          2(-3) + (4) > - 2

or:

-6 + 4 > -2, or -2 > -2.  This end result is false, and so (-3, 4) is NOT a solution of the given inequality 2x + y > -2.

73km 47hm 2dam - 11km 55hm
zvonat [6]

<u>Answer</u>

6,122 hm


<u>Explanation</u>

You can carry out operations on the like terms only. So convert all units to one unit.

I will convert them to dam

1 km =100 dam

73 km = 73 × 100

          =7,300 dam

11 km = 11× 100

         1100 dam

1 hm = 10 dam

47 hm = 47 × 10

            = 470 dam

55 hm = 55× 10

           = 550 dam

73km 47hm 2dam - 11km 55hm = (7300+ 470+2) - (1100+550)

                                                    = 7,772 - 1,650

                                                    = 6,122 hm
