Which of these shows the result of using the first equation to substitute for y in the second equation, then combining like terms?

Option D

Step-by-step explanation:

Equations given in the question are y = 2x and 2x + 3y = 16

As per question we replace y = 2x in the second equation and combination the like terms.

2x + 3(2x) = 16

2x + 6x = 16

8x = 16

Option D will be the answer.

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

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
