PLEASE HELP,, MARKING BRAINLIEST!!! Solve for x

Mathematics
1 answer:
Trava [24]3 years ago

9514 1404 393

Answer:

  x = 10

Step-by-step explanation:

The marked sides are proportional, so we have ...

  x/8 = (x +5)/12

  3x = 2(x +5) . . . . . multiply by 24 to clear fractions

  3x = 2x + 10 . . . . . eliminate parentheses

  x = 10 . . . . . . . . . . subtract 2x

_____

<em>Alternate solution</em>

We observe that the difference between the upper segment lengths is ...

  (x +5) -(x) = 5

and the difference between the lower segment lengths is ...

  12 -8 = 4

This means the upper segment lengths are 5/4 times as long as the lower segments. Then ...

  x = (5/4)(8) = 10

The sales tax in your city is 8.8%, and an item costs $55 dollars before tax. How much would you pay for that item?
IRISSAK [1]

Answer:

The answer is $ 59.84

Step-by-step explanation:

Ok, I know this is not one of the options, but hear me out:

To find the sales tax for that item, you need to multiply the dollar amount by the sales tax (in percent):

$55 * 8.8% = $4.84

So the sales tax is $4.84.  However, the question asks "How much would you pay for that item?", not what the sales tax is.  So I would solve this problem by adding the sales tax to the dollar amount of the item:

$55 + $4.84 = $ 59.84

If you are able to write or type your answer, I would type $ 59.84. If you can only select one of the given values, then I would suggest going with             A: $ 4.84 just because its the only number that is actually relevant at all to the problem.
