value of h makes the equation true is -3.5

Step-by-step explanation:

=> 4h = -14

multiply both side by h

=> \frac{4h}{4}  =  \frac{ - 14}{4 }  \\

=> h =  \frac{ - 14}{4}

divide -14 by 4

÷> h = - 3.5

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

-4 ⇒ Temperature dropping per hour

h ⇒  Number of hours.

-14 ⇒ Temperature after 'h' hours

Step-by-step explanation:

Given:

Current temperature = 0 degrees

Temperature dropping per hour = -4 degrees.

Temperature after h hours = -4h

We need to explain what the equation -4h = -14 represents.

Solution:

Now we know that;

Temperature after h hours = -4h

Now we know that;

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  -4h = -14.

where;

-4 ⇒ Temperature dropping per hour

h ⇒  Number of hours.

-14⇒ Temperature after 'h' hours

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

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5
