To solve for the time it takes to travel a certain distance at a certain speed, use the formula,
time = distance / speed
Given that the entire journey takes four hours, add up the time it takes David to row upstream with that of him travelling downstream. This is mathematically represented as,
total time = time upstream + time downstream
4 = 3/(x - 1) + 3/(x +1)
Solving for x in the equation gives 2. Thus, David's speed in still water is 2 miles per hour.
To solve this, subtract 8.75 from 110, then divide by 9. The answer is 11.25 each pizza. :)
Answer:
4
Step-by-step explanation:
I know cuz Bob said so and so did billy
$1,763.25 X 6 = $10,579.50
$10,579.50 X 1.045^3 = $12,072.97
$12,072.97 - $4,360.00 = $7,712.97
The balance after the withdrawal is $7,712.97
Answer:
x=3
Step-by-step explanation:
WY is an angle bisector, which makes both sides equivalent (it’s an isosceles triangle)
