-5 and -8 both multiply to 40 -5 x -8 = 40 and both add up to -13. -5 + -8 = -13. two negative numbers when added together the answer is still negative. ex: if i owe 2 dollars to someone and 2 to another i owe 4 in total
Let H be the number hats and J the number of jackets. Then, we can write,
Now, since they want 250 items at least, we can write
Hence, the system of inequalities is
Answer: 2 x - 3 y = 6 i think but let let me know if i'm wrong
Take the 133 players and divide by 4.
(133 / 4) = 33.25
33 cars can carry (33 x 4) = 132 players.
But that leaves one player out in the cold with no ride.
You need one more car ... 34 cars all together.
Manipulate the first equation to
y = 22-7z
Then substitute in the second to find z
8(22-7z) + 7z = 127
176-56z+7z = 127
-49z = -49
z = 1
So y = 22-7(1) = 22-7 = 15
y = 15; z = 1
