Question

a. the temp decreased 20.8 degrees over 6.5 hours. what was the average temp change per hour?
b.frank is playing a game where he loses 1.5 points every time a critter eats a carrot. after two rounds, he lost 13.5 points. write an equation to represent the number of carrots the critter ate.

Explanation:

Step1: Calculate hourly temp change

Divide total temp decrease by hours:
$\frac{20.8}{6.5}$

Step2: Solve the division

Perform the decimal division:
$20.8 \div 6.5 = 3.2$
Since it's a decrease, the value is negative: $-3.2$

Step3: Define variable for carrots

Let $x$ = number of carrots eaten.

Step4: Set up the equation

Total points lost = points per carrot × number of carrots:
$1.5x = 13.5$

Answer:

a. $-3.2$ degrees per hour
b. $1.5x = 13.5$ (where $x$ is the number of carrots the critter ate)
