Answer:
7.5 gallons
Step-by-step explanation:
We know that 1 gal = 3.8 L, and we have 28.5 L. So, set up a proportion:
1 gal / 3.8 L = x gal / 28.5 L , where x is the number of gallons the cafeteria made
Cross-multiply:
1 * 28.5 = 3.8 * x
28.5 = 3.8x
Divide by 3.8:
x = 28.5 / 3.8 = 7.5 gallons

Answer:
<em>x = -2, y = -1</em>
Step-by-step explanation:
<u>System of Equations</u>
Solve the system:
y = 1/2x
y = -x - 3
Multiplying the first equation by 2:
2y = x
Substituting x in the second equation:
y = -2y - 3
Adding 2y:
3y = -3
y = -3/3
y = -1
And x = 2*(-1) = -2
Solution: x = -2, y = -1
2.75 hours.
The equation would be 32x + 46 = 134. So we subtract 46 from 134 and get 88. Now we have to divide that by 32 to get the total of 2.75 hours
