Answer:
1st -6x + 15
2nd 5x + y - 17
Simplified = -x + y -2
Step-by-step explanation:
Just add like terms if that's what it's asking.
Answer: I'm gonna go on a wild guess and say its 12.
Step-by-step explanation: I added 16 and 8 then divided it by 2. I did this a couple of years ago so I cant give you a solid answer. Hope someone can help you properly :)
Answer:
$114.17
Step-by-step explanation:
First we need to convert cubic yard to cubic feet.
One yard is equivalent to three feet, so one cubic yard is 3^3 = 27 cubic feet.
So the cost of one cubic feet is 64/27 = $2.3704
We also need to convert from inches to feet.
One inch is 1/12 feet, so 2 inches is 2/12 = 1/6 feet
Now we need to find the volume of the slab:
Volume = 17 * 17 * (1/6) = 48.1667 ft3
Now, to find the cost, we can use a rule of three:
1 cubic feet -> $2.3704
48.1667 cubic feet -> X
X = 48.1667 * 2.3704 = $114.1743
Answer:
4/20 or 1/5 if you want it simplified
1 + 2 + 3 + 4 + 5 + 67 + 8 = 90
I think this is what you mean right?
