The price of album y is $5.80. I solved the system of equations of B and C. Getting rid of the variable z, I was able to get rid of x next. Solving this system gave me $5.80 without having to substitute into the other equation.

A rectangle has a length of x + 5 and width of x - 3. What is the area of the rectangle? Write the answer as a polynomial in sta
goldfiish [28.3K]

Answer:

Step-by-step explanation:

Area = length * width

length: x + 3

width: x - 5

A = (x + 3)(x - 5)

Simplify (x + 3)(x - 5) using the FOIL method:

 

1. First numbers: multiply the first number of each binomial together--x*x = x%5E2

2. Outer numbers: multiply the outer number of each binomial (out of the entire expression, the number farthest to the left (x) and the number farthest to the right (-5))--x*-5 = -5x

3. Inner numbers: multiply the inner number of each binomial--3*x = 3x

4. Last numbers: multiply the last number of each binomial--3*-5 = -15

==> Now, add all of the results together and combine like terms: x%5E2+-+5x+%2B+3x+-+15 = x%5E2+-+2x+-+15

Therefore, A = x%5E2+-+2x+-+15

20 points<br> How do you convert mass to volume without density?
kherson [118]

Answer:

Well, you could always just put it onto a scale to find the mass. But assuming you aren't talking about a laboratory setting. sorry if its all werid i cant really put it into how it supposed to be

The general formula is:

ρ

=

m

V

where

ρ

is density in

g/mL

if mass

m

is in

g

and volume

V

is in

mL

.

So to get the mass...

m

=

ρ

V

Or to get the volume...

V

=

m

ρ

When you have the volume and not the density, and you want to find mass, you will need to find the density yourself. It's often readily available on the internet.

Just replace "[...]" with the object you want, and if it's not exactly what you need, consider it an estimate.

These days, you should be able to search for the density of any common object.

When you have the density and volume but not the mass, then just make up a mass.

You shouldn't need specific numbers to do a problem. You can always solve a problem in general and get a solution formula. If you need to, just make up some numbers that you know how to use.
