The height of Mount Rogers in Virginia is 5729 feet. After reaching the top, a mountain climber climbs down to a height of 5200 feet. Write an integer that represents the climber's change in height.

Step-by-step explanation:

Given

Height of Mount Rogers in Virginia = 5729 feet

Height covered by the climber = 5200

The climbers change in the height will be the difference in both heights as shown

∆h = h2-h1

∆h = 5729 - 5200

∆h = 529 feet

Hence the integer that represent climbers change in height bus 529feet

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

thats not a system of equations, that is a solution
