3x + 12 = 7x - 18
30 = 4x
15/2 or 7.5 or 7 1/2 = x

Step-by-step explanation:

*Whatever you do to one side of the equal sign you must do to the other!

Move the (coefficients?) to one side of the equal sign

2. Get rid of the constant(Notice the negative sign beside the 18. This means you add to get to 0)

3. Separate the number from the variable by dividing because 4x= 4 times x. You must do the inverse operation to get rid of the 4. (Inverse of addition is subtraction, Inverse of subtraction is addition, Divisions multiplication and multiplications division)

Since 4 doesn't go into 30 evenly, I chose to keep it as an improper fraction. If you'd prefer mixed number: 7 2/30

Sorry if it's confusing! Hope I helped! :)

Sherry has a package in the shape of a rectangular prism. What is the volume, in cubic inches (in.), of the rectangular prism? (

Rudiy27

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the dimension of the prism is not given. However, the following steps can serve as a guide for you.

The volume of a rectangular prism is calculated as thus:

$Volume = Length * Width * Height$

So, Take for instance

$Length = 2\ in$

$Width = 3\ in$

$Height = 4\ in$

The Volume would be:

$Volume = 2\ in * 3\ in * 4\ in$

$Volume = 24\ in^3$

Consider two investments, one earning simple interest and one earning compound interest. If both start with the same initial de

Len [333]

Answer:

Ratio between balances will be:

$(x*(1+i)*n)/(x*(1+i)^n)$

Where;

x = deposit

%i = interest rate annual

n = years

Step-by-step explanation:

Lets say first deposit is x$ for both investment and annual interest rate for both investment are %i. Also, they stayed under i interest in n years:

Total balance for simple interest is:

$Total balance=x*(1+i)*n$

How ever total balance for compound interest is:

$Total balance=x(1+i)^n$

Can someone please explain?

This is an isosceles triangle. The angles at the base are congruent (they have the same measures).

Look at the picture.

We know: The sum of the measures of angles in a triangle is equal 180°.

Therefore we have the equation:

$2x-10+2x-10+3x+25=180$ <em>combine like terms</em>

$(2x+2x+3x)+(-10-10+25)=180$

$7x+5=180$ <em>subtract 5 from both sides</em>

$7x=175$ <em>divide both sides by 7</em>

$x=25$

$m\angle A=2x-10\to m\angle A=2(25)-10=50-10=40\\\\m\angle C=m\angle A=40\\\\m\angle B=3x+25\to m\angle B=3(25)+25=75+25=100^o$

<h3>Answer: D. m∠C = 40</h3>
