Answer:
9 canvases
Step-by-step explanation:
To find the number of canvases Rogelio can buy, we just need to divide the value of the gift card by the value of each canvas. Then, if the result is decimal, we round down, because if we round up we will not have enough money to buy them all.
So we have that:
Number of canvases = 100 / 10.99
Number of canvases = 9.099
Rounding down, we can buy 9 canvases
I believe the answer would be A. C=200x+ 70. Hope this helps!
Answer:
3 miles away from the house
Step-by-step explanation:
6 * 3 =18
18 - 15=3
The original price of the meal was $13.47 because 20% of 18.50 is 3.7 you subtract it from 18.50 and then you get 14.8 then you do 9% of 14.8 and get 1.332 and subtract that from 14.8 and get 13.468 and round to the nearest hundred.
The key idea here is that
speed of plane in wind = (speed of plane in air) + (speed of wind)
Let
be the speed of the plane in still air, and
the wind speed. A tailwind blows in the same direction as the plane, so for the first leg of the trip, we have
![158\,\dfrac{\rm km}{\rm h}=s+w](https://tex.z-dn.net/?f=158%5C%2C%5Cdfrac%7B%5Crm%20km%7D%7B%5Crm%20h%7D%3Ds%2Bw)
For the return trip, the wind would blow in the opposite direction:
![112\,\dfrac{\rm km}{\rm h}=s-w](https://tex.z-dn.net/?f=112%5C%2C%5Cdfrac%7B%5Crm%20km%7D%7B%5Crm%20h%7D%3Ds-w)
Solve this system and you'll find
and
