Answer:

231q^3

Step-by-step explanation:

Just add them together. They have the same expressions. Whenever you see a number with an ending similarly to another such as 3x and 2x, they can add together.

This is no different. If something is 6x^2 and another is 7x^2, you would add them to get 13x^2.

Marcie bought a total of 20 used books and cds during a yard sale for a total of 54.50$. of books cost 1.50$ each and cds 5$ eac

melomori [17]

Let numbers of books be 'b' and numbers of CDs be 'c'

We can set up two equations:
Equation [1] ⇒ $b+c=20$
Equation [2] ⇒ $1.50b+5c=54.50$

We are solving for the number of books and the number of CDs bought

When we have two equations in terms of two different variables; $b$ and $c$ , that we need to solve, then this becomes a simultaneous equation problem.

First, rearrange Equation [1] to make either $b$ or $c$ the subject:
$b+c=20$
$b=20-c$

Then we substitute $b=20-c$ into Equation [2]
$1.50b+5c=54.50$
$1.50(20-c)+5c=54.50$
$30-1.50c+5c=54.50$
$5c-1.5c=54.50-30$
$3.5c=24.50$
$c=7$

Now we know the value of $c$ which is $c=7$ , substitute this value into $b=20-c$ we have $b=20-7=13$

Answer:
Numbers of books = 13
Numbers of CDs = 7

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$d = \sqrt{ ({2 - 4})^{2} + ({7 - 2})^{2} }$

$d = \sqrt{ ({ - 2})^{2} + ({5})^{2} }$

$d = \sqrt{4 + 25}$

$d = \sqrt{29}$

Find the slope pf the line on the grap (-2,2),(4,0) reduce all fractional answers to the lowest term.

wariber [46]

Hey there! :)

We're trying to find the slope of the line on the graph (not given, but that's okay). We're given the points (-2, 2) and (4, 0).

Using the slope equation, we simply just have to plug our points in and boom - there's your slope!

Slope equation : m = y₂ - y₁ / x₂ - x₁

Now, using our given points, we can very simply plug everything in! :)

Now, in case you didn't know which number aligns with which variable, I'll go ahead and help you out with this.

x₁ = -2 , x₂ = 4 , y₁ = 2 , y₂ = 0

Now, let's plug and chug!

m = (0 - 2) / (4 - (-2))

Simplify.

m = -2 / 4 + 2

Simplify.

m = -2 / 6

Simplify.

m = -1/3

So, our slope is -1/3.

~Hope I helped!~
