Answer:
13
Step-by-step explanation:
32-2=30
30+7=37
50-37=13
Answer:
Step-by-step explanation:
x+y=12
x-y=18
Now eliminate the y by adding the two equations together to get
2x=30
x=15
then solve for y.
15+y=12
15-y=18
y= -3
Answer:
The current temperature on the X scale is 1150 °X.
Step-by-step explanation:
Let is determine first the ratio of change in X linear temperature scale to change in Y linear temperature scale:



The difference between current temperature in Y linear scale with respect to freezing point is:


The change in X linear scale is:



Lastly, the current temperature on the X scale is:


The current temperature on the X scale is 1150 °X.
Y=-5X which is the equation you use to figure out the answer
