X = y + 11
2x + y = -2
2(y + 11) + y = -2
2y + 22 + y = -2
3y + 22 = -2
3y = -24
y = -8
x = y + 11
x = -8 + 11
x = 3
Solution set {3, -8} (C)
Sqrt55. Use the pythagorean theorem; 3^2 + x^2 = 8^2
Answer: 50° Fahrenheit
Step-by-step explanation:
Here, the equation that shows the temperature of x degree Celsius in Fahrenheit is,

Where x is a variable.
Thus, For the temperature of 10° Celsius,
x = 10° Celsius
The temperature in Fahrenheit is,


Thus, the increasing temperature by 10° C is equivalent to increasing temperature by 50° F.
