Choose all of the linear equations that have no solution. 2(x + 5) − 7 = 3(x − 2)
6x + 1 = 2(x + 3) + 4x
5x + 10 = 5(x + 2)
4x − 1 = 4(x + 3)
3(2x + 4) = 8x + 12 − 2x

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?
