<span>Q=20×0.11×<span>(75−25)</span></span>
<span>⇒Q=20×0.11×50</span>
<span>⇒Q=110<span> cal
Bu doing this you have the required heat represented as Q that is supposed to raise the temperature of fork that will be equivalent to the mass multiplied by the specific heat and also by the change in temperature</span></span>

Answer:
y = 3
x = 2
Step-by-step explanation:
x+y=5 == -2x - 2y = -10
