julia-pushkina [17]3 years ago
5 0

Answer:

0=0  

The input is an identity: it is true for all values

Step-by-step explanation:

3 ( 4 − 7 ) = − 2 1 + 1 2

Solve

Distribute

     3(4z−7)=−21+12z

1 2 − 2 1 = − 2 1 + 1 2

Rearrange terms

1 2 − 2 1 = − 2 1 + 1 2

1 2 − 2 1 = 1 2 − 2 1

add  2 1   to both sides of the equation

12 − 2 1 = 1 2 − 2 1

1 2 − 2 1 + 2 1 = 1 2 − 2 1 + 2 1

simplify

Add the numbers

12z = 12z

Subtract 12 from both side of the equation

1 2 = 1 2

12z- 12z= 1 2 − 12

Simplify, combine like Terms

0=0

Hope this helps.

Melissa is 29 meters below the surface. After swimming 12 minutes she rises upward 15 meters. What is her final depth?
pav-90 [236]

Answer:

The final depth of Melissa is 14 meters below the surface

Step-by-step explanation:

In this kind of problems, involving directions, etc, usually one position is the positive direction and the other position is the negative direction.

In our problem, we suppose that the surface is the positivo zero, above the surface is the positive position(positive depth) and below the surface is the negative directions(negative depth).

The problem states that Melissa is 29 meters below the surface. So, her initial position is 29 meters in the negative direction, so it is equal to -29.

Then, the problem states that Melissa rises upward 15 meters. Upward is the positive direction, so she moved to the positive direction. It means that we are going to do -29+15 = -14 meters.

It means that the final depth of Melissa is 14 meters below the surface
