Answer:

140

Step-by-step explanation:

First you have to solve for x

20x + 60 = 30x + 20

so you would subtract 20x from both sides

60 = 10x + 20

then subtract 20 from both sides

40 = 10x

then divide both sides by 10

4 = x

then you would put 4 in for x in the equation for angle 1

20(4) + 60

80 + 60

140

Answer:

angle 1=20(4)+60=140 degrees

Step-by-step explanation:

theory : If two parallel lines are cut by a transversal, the corresponding angles are congruent.

so angle 1 and angle 3 are equal:

20x+60=30x+20

60-20=30x-20x

40=10x

x=40/10=4

angle 1 = 20(x)+60

angle 1=20(4)+60=140 degrees

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 .
