Word Problem Inequalities

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.
