Answer
The range in degrees Fahrenheit will be between 41 and 50
Work Step by Step
All we gotta a do is convert 5 and 10 degrees Celsius into Fahrenheit using $C={5\over9}(F-32)$
$5={5\over9}(F_{1}-32)$ Pass 9 to multiply and 5 to divide
$5\left({9\over5}\right)=(F_{1}-32)$ The five's will cancel out and the 32 will pass to the other side as positive
$9+32=F_{1} =41$
Now for the other value
$10={5\over9}(F_{2}-32)$ Pass 9 to multiply and 5 to divide
$10\left({9\over5}\right)=(F_{2}-32)$ We multiply the numbers on the right and the 32 will pass to the other side as positive
$18+32=F_{2} =50$
The range in degrees Fahrenheit will be between 41 and 50
