The greater sign is > and the less then symbol is <
Using the red arrows on the number line, you can tell which one is bigger or less. The dot is colored in so it has to have a line under it. So for the first one (top, left), The red arrow is pointing to the right side meaning x is bigger than 3. Therefore x ≥ 3.
In the next one (top, right) the arrow is pointing to the negative side so that one must be less than 3. The dot is also colored in meaning it is: x ≤ 3
In the next one (bottom, left) the arrow is pointing to the right, the dot not colored in, so it has no line. Therefore it is x > 3
Last one (bottom right) the arrow is pointing left, dot is white meaning that the answer is x < 3
If you're wondering what the open dots and closed dots mean:
An open dot is used to show that the ray's endpoint is not a component of the solution when the inequality is "strict" ( < or >).
A closed dot is used to denote that the endpoint is a component of the solution for the other types of inequalities (≥ and ≤ ).
Answer:
Step-by-step explanation:
Total amount of apples that Nicole bought was 6 pounds.
Each pound of apple cost $1.50
This means that the total cost of the 6 pounds of apple that Nicole bought would be
6 × 1.5 = $9
The store had a discount of $2 off her total purchase. This means that the amount that was paid is
9 - 2 = $7
If Nicole and her friend then divided the cost of the purchase evenly, let x represent the amount that each of them would pay. Therefore, the expression that can be used to determine how much Nicole and her friend each paid for the apples would be
x = 7/2
Answer:
Solving the equation
for variable n we get ![\mathbf{n=5-2p}](https://tex.z-dn.net/?f=%5Cmathbf%7Bn%3D5-2p%7D)
Step-by-step explanation:
We need to solve the equation
for variable n
Solving:
![15 = 3n + 6p](https://tex.z-dn.net/?f=15%20%3D%203n%20%2B%206p)
Subtract both sides by 6p
![15-6p = 3n +6p -6p\\15-6p=3n](https://tex.z-dn.net/?f=15-6p%20%3D%203n%20%2B6p%20-6p%5C%5C15-6p%3D3n)
Switch sides of equality
![3n=15-6p](https://tex.z-dn.net/?f=3n%3D15-6p)
Divide both sides by 3
![\frac{3n}{3} =\frac{15-6p}{3}\\n=\frac{3(5-2p)}{3}\\n=5-2p](https://tex.z-dn.net/?f=%5Cfrac%7B3n%7D%7B3%7D%20%3D%5Cfrac%7B15-6p%7D%7B3%7D%5C%5Cn%3D%5Cfrac%7B3%285-2p%29%7D%7B3%7D%5C%5Cn%3D5-2p)
So, solving the equation
for variable n we get ![\mathbf{n=5-2p}](https://tex.z-dn.net/?f=%5Cmathbf%7Bn%3D5-2p%7D)
