Explain what the equation
4h = -14 represents.
-4. Temperature dropping per hour
h , Number of hours
-14. Temperature after 'h' hours
What value of h makes the equation true?
What value of h makes the equation true
the equation -4h=-14 represents that after h hours the temperature of the outside environment is -14°C
It means that it takes 3.5 hours for the temperature of the outside environment to be -14°C
h ≥ 3.5
Step-by-step explanation:
Since the temperature after h hours is -4h, the equation -4h=-14 represents that after h hours the temperature of the outside environment is -14°C. To calculate the value of h, we divide both sides of the equation by -4.
Since -4h=-14
Dividing through by -4:
-4h / -4 = -14 / -4
h = 3.5
It means that it takes 3.5 hours for the temperature of the outside environment to be -14°C
The inequality -4h ≥ -14
Solving by dividing through by -4:
h ≥ 3.5
This means that at 3.5 hours the temperature of the outside environment must be greater than or equal to-14°C
the equation -4h=-14 represents that after h hours the temperature of the outside environment is -14°C
It means that it takes 3.5 hours for the temperature of the outside environment to be -14°C
h ≥ 3.5
Step-by-step explanation:
Since the temperature after h hours is -4h, the equation -4h=-14 represents that after h hours the temperature of the outside environment is -14°C. To calculate the value of h, we divide both sides of the equation by -4.
Since -4h=-14
Dividing through by -4:
-4h / -4 = -14 / -4
h = 3.5
It means that it takes 3.5 hours for the temperature of the outside environment to be -14°C
The inequality -4h ≥ -14
Solving by dividing through by -4:
h ≥ 3.5
This means that at 3.5 hours the temperature of the outside environment must be greater than or equal to-14°C
Current temperature is 0 degrees and temperature is decreasing at a rate of -4 degrees per hour so if we multiply -4 from h which number of hours it will show the temperature after h hours.
So we can say that;
-14 will be the temperature after 'h' hours in equation .
Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram
