The following formula gives the temperature's measure in degrees Fahrenheit F, where C is the measure in degrees Celsius: F=9/5C+32

C+32F, equals, start fraction, 9, divided by, 5, end fraction, C, plus, 32
Rearrange the formula to highlight the measure in degrees Celsius. C=

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
