Well, you must first do your equation k=y/x so k= 18/4 or 9/2
now you use the equation y= kx or y= 9/2 times 24... 9/2 times 24 is 108 so y=108
Answer:
-20.1 degrees Celsius
Step-by-step explanation:
The system started at -12.6 Celsius. It then cooled 7.5 degrees during a reaction. Because it cooled, that means the difference is negative.
-12.6 degrees Celsius - 7.5 degrees Celsius = -20.1 degrees Celsius
It is important to always remember your correct names and variables for numbers in chemistry!
First add your x values and your numbers on the left side
-17x + 6x= -11x
15 + -23= -8
New equation is:
-11x-8= 10-8x
Since you can't have 2 x values on different sides, you have two add the least x value to the other one. -11 is smaller
10 + 3X= -8
Subtract 10 on both sides.
3x= -18
Divide by 3
X= -6
