Answer:
B) x = 2, y = 1
Step-by-step explanation:
Add the two equations to eliminate the x-variable.
(x +3y) +(-x +6y) = (5) +(4)
9y = 9 . . . . . . .simplify
y = 1 . . . . . . . . divide by 9
You can substitute this value into either equation to find x.
x + 3(1) = 5
x = 2 . . . . . . . . subtract 3
The solution is (x, y) = (2, 1).
Prism volume = lbh
= 10*8*12
= 960cm^3
Note: I'm assuming the hole was cut right through it...
Hole volume = lbh
= 2*3*12
= 72cm^3
Final volume = 960 - 72 = 888cm^3

Mean: 29
23 + 25 + 25 + 27 + 32 + 35 + 36 = 203
203 / 7 = 29
Median: 27
23, 25, 25, 27, 32, 35, 36
25. You need to divide 3240 by 6, and 1100 by 2. Are those equal? That's what it's asking. It would not be equal, because 3,240 miles would be 540 miles per hour and 1100 would be 550 per hour. Very close, however.
26. If 15 scoops makes 5 gallons, then divide 15/5. That's 3 scoops per gallon. It's asking how many gallons can be made with 6 scoops. That would be 2 gallons.
27. All it's asking is 38 times 5, which would be 190.
28. Since 5 gallons goes into 15 gallons three times, you would divide $22.20 by 3. That would be $7.40 each 5 gallons.
