Each morning soriano buys coffee and donut holes for his employees and clients . each cup of coffee cost $2,50 and each cup of donut holes cost 1.75 . soriano bought 60 cups of coffee and donut holes and spent $123.75.

1) write a system of equations to model this situation

2) solve the system of equations to find the number of cups of coffee and cups of donut holes that soriano bought his employees and clients.

1. are the triangles similar and if so why? what is the value of x? show your work.

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
