A car can travel 135 miles with 5 gallons of gasoline. At this rate, how much gallons of gasoline the car needs to travel 675 mi

labwork [276]

Answer:

25 gallons

Step-by-step explanation:

Given

135 miles to 5 gallons

Required

Determine the number of gallons for 675 miles

From the question, number of miles is directly proportional to number of gallons:

So, we have:

$135\ miles = 5\ gallons$

and

$675\ miles = x$

Where x represents the number of gallons for 675 miles

Cross Multiply:

$135 * x = 675 * 5$

$135x = 3375$

Make x the subject

$x = 3375/135$

$x = 25$

Hence, the car needs 25 gallons

Which function describes the arithmetic sequence shown? 1,-2, -5, -8, -11, ...

antiseptic1488 [7]

Answer:

a(n)=1+(n-1)(-3)

Step-by-step explanation:

Notice there's a common difference of d=-3.

If we use the formula a(n)=a1+(n-1)d to find the nth term given the first term and the common difference, we will see that the function that describes the arithmetic sequence as a(n)=1+(n-1)(-3)
