x is 20

Step-by-step explanation:

x = 5

Step-by-step explanation:

The 2 triangles are similar by the AA postulate then the ratios of corresponding sides are equal , that is

=

= ( cross- multiply )

30(2x + 10) = 40(x + 10) ← distribute parenthesis on both sides

60x + 300 = 40x + 400 ( subtract 40x from both sides )

20x + 300 = 400 ( subtract 300 from both sides )

20x = 100 ( divide both sides by 20 )

x = 5

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay
