<h2>Answer:</h2>

x+10y

<h3>Step-by-step explanation:</h3>

3x+2y+(-2x)+8y

First of all you cannot substitute x with y, so what u do u make the numbers with the same letters they have,and I put -2x because + &amp; - equals to -(minus) :-

3x-2x+2y+8y= x+10y

I don't add 1 to x coze when x alone stands for 1, I added +10y because both the y equations had + they were positive so I add a +.

<h3>Hope it helps </h3>

A rectangular block of copper metal mass is 1896 g. The dimensions of the points
vagabundo [1.1K]

Answer:

8.921513269...g/cm

Step-by-step explanation:

the density has this formula: D= m/V

so to solve the V, which refers to volume, you do: 8.4×5.5×4.6= 212.52, and the m, which refers to mass, you already have it. So the last thing to do is:

D= 1896g/212.52= 8.921513269...g/cm

I hope I've been helpful... good luck...!!!

A student rolls a number cube Whose six faces are numbered 1 through 6 what is the sample space for this experiment.
KiRa [710]

Answer:

It depends on how you define an outcome.

Usually, the outcomes are considered to be the number showing on the top face of the die (number cube) when it comes to rest on a horizontal surface. If that is how you define outcomes, then the sample space is the set of numbers 1–6: {1, 2, 3, 4, 5, 6}.

Step-by-step explanation:

"This experiment" covers a lot of territory. The student could be checking to see if the die stays on the table or falls to the floor. The student could be experimenting to see if the die changes color or makes a certain kind of noise. The experiment could involve the number of times the die rolls over to a new face before it comes to rest. Until the experiment is properly defined, the sample space is unknown.

If the experiment is to see what number shows on the top face of the die at rest on a horizontal surface, then the sample space is presumably the set of numbers 1 through 6.

32. You plan to purchase items for $4000 and will finance the cost with a fixed installment
Paul [167]

Answer:

Amount of finance charge = $800

Interest rate = 5% per year

Step-by-step explanation:

Given:

Cost of item = $4,000

Per month payment = $100

Number of month = 48 month = 48 /12 = 4 year

Find:

Amount of finance charge

Interest rate

Computtaion:

Total amount pay = 100 x 48

Total amount pay = $4,800

Amount of finance charge = Total amount pay - Cost of item

Amount of finance charge = 4,800 - 4,000

Amount of finance charge = $800

Interest = P x r x T

800 = 4,000 x r x 4

800 = 16,000 x r

Interest rate = 5% per year
