Distance, d, is directly proportional to the number of gallons of gas, g. Thus,
d α g
To turn alpha to equal sign, we insert a constant of proportionality, k.
d=kg
To find k, we use the given conditions.
476 = k (14)
k = 34
Therefore, the equation is,
d = 34g
and for travelling 578 miles,
578 = 34g
g = 17 gallons is needed.
The least common multiple of each is 2. 2 x 25= 50. 2 x 30= 60 and 2 x 36=72
Answer:
Solution is the missing word.
Step-by-step explanation:
For this case we have a quadratic equation,
, of the form 
Where:

We can solve the equation by factoring, that is, we bias two numbers that multiplied give as a result -60 and added as a result 28.
These numbers are:

Then, the factorization is given by:

The roots are:

Answer:

(a) He would drive 96 km in an hour because 1152 divided by 12 is 96
(b) He is technically on schedule because he is driving 104 km per hour, instead of 96, so if he keeps driving at the same rate, he should get there in under 12 hours
