Billy makes 
a week in allowance plus 
for each lawn that he mows. This week Billy wants to make over 
. Select the inequality for the number of lawns he needs to mow.
Billy makes
We know that Billy needs to make more than 
between his allowance and the lawns that he mows. This means our inequality should include 
Also, since Billy will make 
per lawn, that means we need to multiply 
by the number of lawns he needs to mow, 
:
So far we have the following:
Next, we know that he makes 
each week, on top of what he makes mowing each law.
This means we need to add the 
to the 
When we put all of these pieces together, we will get the following inequality:

At a fair, there is a game where players step on a scale and weigh themselves. The objective of the game is for the host to guess the player's weight. A player loses if the host of the game can guess the player's weight within 
pounds, inclusive. Suppose a player weighs 
pounds. Write an inequality that represents the range of numbers such that the player loses. (Let 
represent the guess weight.)
At a fair, there is a game where players step on a scale and weigh themselves. The objective of the game is for the host to guess the player's weight. A player loses if the host of the game can guess the player's weight within
For the player to lose, the host has to guess within 
pounds of the player's weight, inclusive. Thus, the host can guess any number between 
pounds 
and 
pounds 
; that is, if 
is the weight the host guesses, then 
, which translates to 
.
For the player to lose, the host has to guess within

Given the following problem, write the inequality.
Seven less than two times a number is greater than fourteen.
Given the following problem, write the inequality.
Seven less than two times a number is greater than fourteen.
Seven less than two times a number is greater than fourteen.
Let's look at the problem step by step.
If we do not know the value of a number, we give it a variable name. Let's say x. So, we see in the problem
Seven less than two times a number is greater than fourteen.
So, we will replace a number with x.
Seven less than two times x is greater than fourteen.
Now, we see that is says "two times" x, so we will write it like
Seven less than 2 x is greater than fourteen.
The problem says "seven less" than 2x. This simply means we are taking 2x and subtracting seven. So we get
2x - 7 is greater than fourteen
We know the symbol for "is greater than". We can write
2x - 7 > fourteen
Finally, we write out the number fourteen.
2x - 7 > 14
Seven less than two times a number is greater than fourteen.
