Whoever does paper homework, This is what you do: Get your homework out. Example: Math or something Find a word problem and google the exact problem with no lower case at the beginning When you google that problem, You will most likely find PDFs. Look through the PDFs. One pdf may have only your problem's answer or one pdf may have answers for the whole page! or even a lesson

Alright,



120=students


150=students


So if a question is asking you the total, then that means you must do addition.


The cost is 720

Solve the simultaneous equation :<br><br> 4x+2y=17<br> 3x+2y=14
enot [183]

Answer:

(x, y) = (3, 5/2)

Step-by-step explanation:

4x+2y=17\\3x+2y=14

I'll solve by elimination here. If you invert the second equation and add it to the first, 2y and -2y would cancel out.

4x+2y=17\\-(3x+2y=14)

Now just add those from top to bottom.

\rightarrow (4x-3x)+(2y-2y)=17-14\\\rightarrow x=3

Nothing else needs to be done for that part. Now, you can pick either equation and use the known value of x to solve for y.

4x+2y=17\\\rightarrow 4(3)+2y=17\\\rightarrow 12+2y=17\\\rightarrow 2y=5\\\rightarrow y=\frac{5}{2}

(x, y) = (3, 5/2)

If an items costs $41.04, including an 8% sales tax, what was the cost of<br> the item before taxes?
tankabanditka [31]

Answer:

$38

Step-by-step explanation:

I solved this by doing a proportion, 41.04/108 = x/100 to find the original price before the 8% tax. To solve this proportion you have to isolate the variable, so you would do the cross product and multiply (41.04 x 100) and have that equal to 108x. So then because you have 108x = 4104, isolate x by dividing by 108 and you get 38, thus $38.

You can also check your work by multiplying 38 by 0.08 to find the amount of sales tax added, and if you do this you will get the value $41.04.
