A mountain climber ascends a mountain to its peak. The peak is 12,740 ft above sea level. The climber then descends 200 ft to meet a fellow climber. Find the climbers elevation above sea level after meeting the other climber. 1.12,540 ft 2.–12,540 ft 3.10,740 ft 4.12,940 ft
Evaluate –x for x = –1.8 2.– Simplify the expression.
The temperature on a summer afternoon is 85°F. Define a variable and write an expression to find the temperature after it changes. Then evaluate your expression for a decrease of 11 degrees Fahrenheit c; 11 + (–85) = c; 85 + (–11) = – c; 11 – (–85) = – c; 85 – (–11) = 96
