Jose drove 380 miles using 14 gallons of gas. At this rate, how many gallons of gas would he need to drive 418 miles?

PSYCHO15rus [73]

Hey there,
380 miles = 14 gallons
1 miles = 14 / 380
= 7 / 190
418 miles = 7 / 190 x 418
= 15.4 gallons.

Hope this helps :))

Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour?

boyakko [2]

Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286

And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)

The larger of two numbers is eight more than three times the smaller number. The sum of the two numbers is 48. Find the two numb

Anarel [89]

Answer: the smaller number is 8. The larger number is 38

Step-by-step explanation:

Let x represent the smaller number.

The The larger of the two numbers is eight more than three times the smaller number. It means that the larger number is 3x + 8

The sum of the two numbers is 48. It means that

x + 3x + 8 = 48

4x + 8 = 48

4x = 48 - 8 = 40

x = 40/4 = 10

Substituting x = 10 into 3x + 8, it becomes

3 × 10 + 8 = 38
