When you set
, you end up with the differentials
. Multiplying both sides by 2 gives
.
Then the integral is
Answer:
So first you do $0.50 x 3 = 1.5
then you add that to $12.00
$12.00 + 1.5 = 13.5
13.5 is the cost of one pizza.
Since they bought 12:
The total cost of the 12 pizza is $162 <== not important
<u>13.5 divided by 8 is 1.687</u>
<u>round 1.56875 to the nearest cent 1.7 = $2</u>
so each slice costs $2
Hey there!
Since we don't know how many hours it took, we'll say 9 mph = 3 miles/x hours. To solve, we multiply both sides by x. 9x = 3 Dividing both sides by 9, we get that it took 3/9 hours or 1/3 hours. How many minutes are 1/3 hours? 20, so it took Derrick 20 minutes. Hope this helps! :)

Answer:
9/14
Step-by-step explanation:
(3/7)/(2/3) Flip the sign of the second term and multiply.
(3/7)*(3/2)
15 is the answer because 8-5 is 3 and 3 and 4 is 12 so 12 plus 3 is 15
