On an X temperature scale, water freezes at −125.0^o X and boils at 375.0^o X. On a Y temperature scale, water freezes at −70.0^o Y and boils at −30.0^o Y. The value of temperature on X-scale equal to the temperature of 50.0^o Y on Y-scale is: On an X temperature scale water freezes at −125.0^o [...]
