Hassan wants to save $700 to buy a TV. He saves $17 each week. The amount, A (in dollars), that he still needs after w weeks is given by the following function A (w) = 700 - 17w

it will take 2.5 hours until Noah and Andre meet.

Step-by-step explanation:

Noah and Andre are 15 miles apart on a bike path when they start biking towards each other. This means that by the time they would meet, they would have covered a total distance of 15 miles.

Let t represent the time it would take for them to meet.

Distance = speed × time

Noah rides at a constant speed of 4 miles per hour. This means that the distance that Noah would cover in t hours is 4t

Andre rides at a constant speed of 2 miles per hour. This means that the distance that Andre would cover in t hours is 2t

Since the total distance is 15 miles, then

4t + 2t = 15

6t = 15

t = 15/6

t = 2.5 hours
