Answer:

18x

Step-by-step explanation:

Since all 3 are monomial terms with the same variable, we can add them together:

5x + 3x = 8x + 10x = 18x

Answer: 18x

Explanation: The three parts of this expression, +5x, +3x, and +10x are called terms and the numbers in front of the variables, +5, +3, and +10 are called coefficients.

Because the variables, x, x, and x are identical,

the three terms in this problem are called like terms.

Like terms can be added together

by simply adding their coefficients.

So in this problem, since 5 + 3 + 10 is 18, 5x + 3x + 10 is simply 18x.

Explain that you found the volume of water in the fish tank if it was only one and a half full with water show your work and sol

Reptile [31]

Answer:

The volume of water in the fish tank is 4.5 cubic feet

see the explanation

Step-by-step explanation:

The complete question is

Explain how you found the volume of water in the fish tank if it was only 1/2 full with water. Show your work and solution. Don't forget your UNITS!

You have a fish tank with the following dimensions:

Height: 3 feet

Width: 1.5 feet

Length: 2 feet

step 1

Find the volume of the fish tank

The volume of a rectangular prism ( fish tank) is equal to

$V=LWH$

substitute the given values

$V=(2)(1.5)(3)=9\ ft^3$

step 2

Find the volume of water in the fish tank

Remember that

The fish tank it was only one and a half full with water

Multiply the volume of the fish tank by one and a half to obtain the volume of water

$\frac{1}{2}(9)=4.5\ ft^3$

Serhud [2]

Answer:

SF = 7/3

Step-by-step explanation:

Like the problem hint says, you want to put the new coordinate over the old one to find the scale factor. We'll use both x and y.

-7/-3 = 7/3

14/6 = 7/3

Therefore, the scale factor is 7/3.
