You are returning to the united states from a trip to europe. you purchased the following items:

2 scarves at $50 each (use your $100 exemption for this one).
silver jewelry for $175
chinaware for $200

how much duty must you pay? $ .

overall, what percentage of the cost of these articles do you pay in duty? %

if you later find that you have gotten the same goods in the united states for a 20% markup; would you have saved more by buying them in the united states rather than in europe (ignoring cost of travel)?

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

i believe that the answer is

b. y-1=-2(x-4)

hope this !

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
