Answer:

4x - 20

Step-by-step explanation:

Combine like terms (those with the same amount of variables:

x + x + x + x = 4x

4x - 20 => Note: You cannot combine these two terms, because they do not have the same amount of variables (one having one variable (x), the other being a constant (no variable) ).

My coffee mug weighs 200 g and hold 260cm3 .

yarga [219]

The coffee mug when filled will weigh 460 g

<h3>Calculating mass</h3>

From the question, we are to determine the weight of the mug if filled with water

From the given information,

The weight of the coffee mug is 200 g and holds 260cm³.

If filled with water, the volume of the water will be 260cm³.

Now, we will determine the mass of this volume of water

Using the formula,

Density = Mass/Volume

∴ Mass = Density × Volume

Volume = 260 cm³

Density of water = 1 g/cm³

∴ Mass of the water = 1 × 260

Mass of the water = 260 g

Mass of the coffee mug when filled with water = Mass of the coffee mug when empty + Mass of water

Mass of the coffee mug when filled with water = 200 g + 260 g

Mass of the coffee mug when filled with water = 460 g

Hence, the coffee mug when filled will weigh 460 g

Find the 92nd term of the arithmetic sequence -29, -22, -15, ...

kompoz [17]

Answer:

608

Step-by-step explanation:

The appropriate general formula here is a(n) = a(1) + (n -1)d, where d is the common difference. Here, d = +7. Thus:

a(92) = -29 + (92-1)(7) = 608

Ann is growing two different plants for a science project. Plant A grew 4/12 inch the first week and 2/12 inch the second week.

Galina-37 [17]

Start the number line from 0 and put divisions at 1/12. Then mark at 4/12 for plant A and indicate this was its growth in the first week. Then, make another mark up to 6/12 and indicate this was the plant's growth in the second week.
For plant B, make one mark at 7/12 and indicate that this is plant B's growth in the first week.

After two weeks, plant A has a height of 6/12 inches and plant B has a height of 7/12 inches, so B is taller.
