Answer:
630m³
Step-by-step explanation:
volume= 7m×9m×10m=630m³
from the given equation
X+Y=20-->i
X-Y=14--->ii
add eq i and eq ii
2x=34
x=17
putting the value of x=17 in eq i
17+y=20
then y = 3 so the right answer is
17 and 3
Answer:

Step-by-step explanation:
Let the number of cups of onions Katrina still needs to chop = x
She has already chopped the onions =
cups ≈
cups
So total amount of chopped onions =
cups
Since, onion soup recipe calls for the chopped onions =
cups ≈
cups
Therefore, equation which shows the number of cups of onions to be chopped more will be,

We further solve this equation for the value of x,
x = 
x = 
=
cups
≈
cups
First we need to find the total amount of servings needed.

24 servings/10 people
Now we can find the amount of pans needed
24 servings/8 servings (1 pan)
=3 pans
She needs at least 3 pans
