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.

I DONNT UNDDERSTAND THIS AT ALL

Answers

Answer:

Here's exactly what I would write:

a = Sandy cupcakes, b= Sandy gummy bears, c = Sandy brownies, d = Nina cupcakes, e = Nina gummy bears, f = Nina brownies

a = 4d

b = 3e

c = 2f

Expression for Sandy: 4d + 3e + 2f

Expression for Sandy and Nina: 5d + 4e + 2f

Step-by-step explanation:

This is a terrible question that makes people feel frustrated. I'm sorry.

a = Sandy cupcakes, b= Sandy gummy bears, c = Sandy brownies,

d = Nina cupcakes, e = Nina gummy bears, f = Nina brownies

Sandy has 4 times the number of cupcakes as Nina: a = 4d

Sandy has 3 times the number of gummy bears as Nina: b = 3e

Sandy has 2 times the number of brownies as Nina: c = 2f

An expression for how many desserts Sandy is bringing: a + b + c

An expression that could be used for how many desserts Sandy and Nina are bringing together: a + b + c + d + e + f, but I think they want you to substitute the equivalent values like above (a = 4d)

Sandy: 4d + 3e + 2f

Sandy and Nina: 5d + 4e + 2f

because 4d + 3e + 2f + d + e + f = 5d + 4e + 2f

I'm sorry I don't have a simpler way to explain this. It's a painful question. I will answer any questions  you have.
