Solve the following system using elimination.

2x-4y=10
x+5y=40

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label

He that is measured at 220° is a reflex angle. the opposite angle is obtuse. find the measure of obtuse .

X2 + y 2 = 36 x + y = 6 solve the system of equations.
