1. Calculate how many hours passed between her temperature checks. 8 p.m to 8 a.m. is 12 hours.
2. Calculate the total change in temperature. 36 - 54 is -18, so the temperature went down by 18 degrees.
3. We are looking for degrees per hour, so we put derees(18) over hours (12) to get 18/12.
4. Calculate by dividing. The answer is 1.5 degrees per hour.
3.4
5.14
______
8.54
If we round the answer
We get 8.5
Guess I gave you the correct answer
Answer:
I(x)=x+1
Step-by-step explanation:
<h3>
1)</h3>
• 6x -2(x -5) = -2 . . . . given
• 6x -2x +10 = -2 . . . . X Cameron errored here. When multiplying -2 by -5, the result is 10, not -10.
• 4x +10 = -2 . . . . . . x terms are correctly collected
• 4x +10 -10 = -2 -10 . . . . add the opposite of the constant on the left
• 4x/4 = -12/4 . . . . divide by the x-coefficient
• x = -3 . . . . . . . . . . simplify
<h3>2)</h3>
• 11x -10 = -34 . . . . combine like terms
• 11x -10 +10 = 34 +10 . . . . addition property of equality
• 11x = 44 . . . . . . . . simplify
• 11x/11 = 44/11 . . . division property of equality
• x = 4 . . . . . . . . . . . simplify
