How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? Or how are they different. Explain one of the two or how their similar and different. Thanks :)
I give brainliest to whichever makes the most sense

Answers

Answer:

They are different because in the mantle, the magma is heated, it becomes less dense and rises. It give off it's thermal energy and cools down, becoming more dense and descend to be heated again.

In the ocean, the tropics warm the water and it travels to the poles to cool down, then returns to the tropics to heat up again.

they are similar in the ways that they move and create energy.

4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?

please drop an explanation, and equation thanks!

Answers

Ok so we want to cross multiply.
To do this you know 4/9=2$ so now you want to know 1=x$
When you do this you get $5

Answer:

1 kg of baking soda costs $4.50.

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

 4/9 kg            $2

------------- = --------------

    1 kg               x

Multiplying both numerators by 9, we get:

  4 kg          $18

------------ = ---------

   1 kg             x

Cross-multiplying, we get 4x kg = $18-kg.  Solving for x, we get:

        $18-kg

x = -------------- = $4.50

         4kg

1 kg of baking soda costs $4.50.

what is the value of x

Answers

Answer:

x = 105

Step-by-step explanation:

Skills needed: Triangle Angle Measures, Solving a One-Variable Equation

1) To get the answer, you need to know that all the angles inside a triangle add up to 180 degrees. This is very important in the future as well.

2) So to find x, we can make the equation: x + 30 + 45 = 180

3) You can combine like terms:

30 and 45 can be combined --> 30 + 45 = 75

4) Based on step 3, you can get: x + 75 = 180

Subtract 75 from both sides, and you will get: x = 105

Hope this helps and have a nice day! :] :) :D

3x + 2 = -55 i need all the steps

Answers

Answer:

-19

Step-by-step explanation:

3x+2 = -55

   -2         -2

3x = -55-2

3x = -55+-2

3x = -57

/3      /3

x=-19

Answer:

-19

Step-by-step explanation:

[tex]3x + 2 = -55[/tex]

[tex]3x = -55[/tex]

       [tex]-2[/tex] (2 is negative because it was moved to the other side of the equation)

[tex]3x/3 = -57/3[/tex]   (Divide both sides of the equation by 3 to isolate x.)

[tex]x = -19[/tex]
