No, they are not equivalent.

9w ×0 is already 0.
0 - 12 = -12

-12 doesn't equal 9w - 12.

Hope this helps!

In Germany, VAT is at 19%
aleksley [76]

Answer:

Amount of VAT paid by Jeremy is € 9.31 .

Step-by-step explanation:

As given

In Germany, VAT is at 19% .

Jeremy buys a calculator in Germany for €58.31


This price includes VAT.

Let us assume that the cost of calculator excluding tax is x .

19% is written in the decimal form .

= \frac{19}{100}

= 0.19

VAT Price = 0.19 × Cost price of calculator excluding VAT

                 = 0.19 × x

                 = 0.19x

Than

Cost of calaculator + VAT price = Cost of calculator including VAT

x + 0.19 × x = 58.31

x + 0.19x = 58.31

1.19x = 58.31

x = \frac{58.31}{1.19}

x = €49  (Approx)

Thus cost price of calculator excluding VAT is €49  .

VAT Price = 0.19 × Cost price of calculator excluding VAT

                = 0.19 × 49  

                 = € 9.31

Therefore the amount of VAT paid by Jeremy is € 9.31 .

Please help me with this 20 points
JulsSmile [24]

Answer:

A  4/605

Step-by-step explanation:

mathematics = 11 letters

P(m) = number of m's/total = 2/11

we replace it so we have  mathematics = 11 letters

P(s) = number of s's/total = 1/11

not replacing it

we replace it so we have  mathematic = 10 letters

P(vowel) = number of vowel/total = 4/10 = 2/5

P(m, replace,s, no replace, vowel) = 2/11*  1/11 * 2/5 =  4/605
