A friend just asked if I want to see Wide shot of Zach in
a movie later. I’m not sure. I need front of a movie
eight dollars to go to the movie.

But I owe my brother ten dollars.

I need to figure out if the amount
of money I have is enough to go
to a movie and pay my brother
back. Hey – I can use an
inequality to help me.
Whiteboard
2a
Write a sentence as an inequality.
Twice a number is at least –2.
Let’s walk through some
examples of what it means to
write a sentence as an inequality.
Transition to Zach
looking in his wallet. No
money should actually
be visible.
Transition to
whiteboard
Add words in the
sentence one by one in
sync with audio.
To write a sentence as an
inequality, just write what is in the
sentence using numbers and
symbols.
What do you think “Twice a
number is at least –2” means?

Write a sentence as an inequality.
I can pick the letter x to represent
‘a number,’ which means that it is
unknown. Twice a number is 2
times x.
Twice a number is at least –2.
2c
2x
Write a sentence as an inequality.
Ok, now I need an inequality
symbol that means “at least.”
Twice a number is at least –2.
2x
2d
³
Write a sentence as an inequality.
It seems a bit weird, but I need
the greater than or equal to
symbol because a number that is
at least negative 2 must be
greater than or equal to negative
2.
The last part is easy. Negative 2
is written as negative 2.
Twice a number is at least –2.
2x

–2

So the inequality for our sentence
is two x is greater than or equal
to negative 2.
Keep direction line and

part in sync with

2i
Write a sentence as an inequality.
The first part is a mouthful, but
I’ve got this. I’ll use y for my
number this time, so three more
than the product of 4 and a
number is 4 times y (pause) plus
3.
“Is at most” is a little tricky.

I need to use the less than or

means that 7 is the greatest
value it could have, but values
less than 7 would be OK.
And again, the last part is easy, 7

Write a sentence as an inequality.
The sentence “ten less than a
number is more than 8” describes
the situation. Why?
Ten less than a number is more than eight.
The number is the amount of
money I have. ‘Ten less’ is
because I have to pay my brother
back 10 dollars, and ‘more than
8’ is because I have to have at
least 8 dollars for the movie.

2m
Write a sentence as an inequality.
Ten less than a number is more than eight.
I will use the letter h for “a
number.” Then I will write ten
less than a number as “h minus
10.”

must extend across
width of screen on one
line.]

What does this tell me? Any

inequality true, is an amount of
money that gives me enough to
pay back my brother and go to a

Twenty dollars! I can go to the
movie because 20 minus 10 is 10
