How do you figure out how long you have before the Galapagos Zombie Tortoises eat you? By using math, of course. If you can't solve this problem, we feel bad for you, son: we've got 99 word problems, and "Inequalities" is one.
Here are your options. The open part of the symbol should face whichever
value is greater...
Just like the gaping maw of the zombie tortoise opens wide, hungry for delicious brains...
Or an ankle... since they're pretty low to the ground.
Anyway, the answer is B. Since Z is greater than or equal to three thousand, you want
to put a line under the symbol. You need to get off the island. You know how
zombies are slower than humans? Zombie tortoises are even slower than regular tortoises. You
have a lot of time.
You have at most fourteen days before the zombies reach you. If "d" equals your days
to live, how would you express this with an inequality?
Here are your choices: Don't worry, we have plenty of time to break
this down. "At most" can also mean "fourteen or fewer."
B shows "greater than," so that one's out.
D is equals, so that one's out too. You could have fewer than fourteen days, so you better
play it safe.
"Fourteen or fewer" also means that "d" is "less than or equal to fourteen."
So the answer is C. So you have two weeks before those zombie
tortoises start munching away on your brain.
Slow and steady may not win this race.
