If Jack and Jill walk an average of 5 miles per hour how long would it take for Dave to his school that is 2.5 miles away?

YES I GET THE POINTS. ME. M

Step-by-step explanation:

im here first noobs hahahahahahhaha

So the runner is walker is 2.5 minutes per mile. We can multiply this unit rate by the number of miles:

2.5minutesmile×5 miles=12.5 minutes

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
