He used 9 4/5 cups of tomato sauce in total. We also know he spent 4 1/5 + 3 2/5 which is 7 3/5. Now we can subtract. Make both numbers into improper fractions to get 49/5 - 38/5. We get 11/5, or 2 1/5. Hope this helped!
Can you post a picture of the graph please
12% of what number is 18...." of " means multiply, " is " means equals
0.12x = 18
x = 18/0.12
x = 150
check..
12% of 150 = 18
0.12(150) = 18
18 = 18 (correct)
yep...its 150

Step-by-step explanation:
You are given the system of two equations with three variables:

Write the augmented matrix for this system of equations

Now, find the reduced row-echelon form of the augmented matrix for this system of equations. Subtract the second row from the first row:

You get the system of two equations:

From the second equation

Substitute it into the first one:
