Answer:

A, B, & C

Step-by-step explanation:

A: -5x +12 = -12x - 12

    +12x        +12x

    7x + 12 = -12

         -12     -12

            7x = -24                 [Divide both sides by 7 to get x]

              x = -24/7

B: −5x + 12 = 5x + 12

   -5x            -5x

    -10x + 12 = 12

            -12     -12

            -10x = 0                   [Divide both sides by -10 to get x]

                 x = 0

C: −5x + 12 = 5x − 5

    -5x           -5x

    -10x + 12 = -5

            -12      -12

           -10x = -17                  [Divide both sides by -10 to get x]

               x = 17 / 10

D: −5x + 12 = −5x − 12

    +5x           +5x

              12 ≠ -12         [The statement is false, so it isn't the correct answer]

nekit [7.7K]
You would find the probability of getting an answer less than 10 by counting all of the possible outcomes, or numbers that are less than 10 and compare them to the total number of possible outcomes, or the total number of numbers. You would write the ratio of predicted outcomes to total possibilities.

The answer would be 4/9.

ABC ≃DEF. Find the lengths of the given sides
GuDViN [60]

Answer:

BC = 8 and EF = 8.

Step-by-step explanation:

Since triangle ABC and DEF are congruent to each other, BC corresponds with EF (as determined by the triangle names).

Set BC and EF equal to each other.

x + 6 = 3x + 2

Subtract x from both sides.

6 = 2x + 2

Subtract 2 from both sides.

4 = 2x.

Divide 2 on both sides.

x = 2.

Substitute 2 for x.

BC = 2 + 6

BC = 8

Since we already know that EF is congruent to BC, EF is also 8.

EC = 3(2) + 2

EC = 6 + 2

EC = 8

siniylev [52]

Answer:

The statement is false.

Step-by-step explanation:

If the modeling is with multiple variables it is necessary for all the variables to be modeled well such that the criticality of the model is dependent on all the variograms. It is not dependent on the cross variograms only.
