Which number line models the solution set of the following problem? One less than twice a number is no less than five. What is t
Nadya [2.5K]

Answer:

Option 1.

The solution set is: {n|n is a real number, n≥3}


Step-by-step explanation:

1. You must read carefully the information given in the problem: "One less than twice a number" indicates that you must write a number n multiplied by 2 and subtract 1 from this term, as following:

2n-1

2. "is not less than five" indicates that the result must be equal or greater than 5. Then, you obtain the following expression:

2n-1\geq5

3. Now, you can solve for n. Then, you obtain:

2n-1\geq5\\2n\geq6\\n\geq\frac{6}{2}\\n\geq3

4. Then, the solution set is: {n|n is a real number, n≥3}.

5. The correct plot on the number line must show a circle on 3 (You must fill in the circle if the sign is \leq or\geq) with a line from that circle to the right.

5. Therefore, the answer is the first option.

Why is division not commutative
Kamila [148]
Division CANNOT be commutative, here is why

lets say the problem is 24÷4

it is obviously  6

but when you flip 24÷4, you get 4÷24

and... 4÷24 is 0.16666666

6 and 0.1666 is totally different :p

Amanda uses her Credit card to purchase $75 of materials Amanda pays her credit card off each month
stealth61 [152]

The remaining balance that Amanda will pay when the credit card is used to pay $75 from the total amount is $125.

<h3>How to compute the amount?</h3>

Your information is incomplete. Therefore, an overview will be given. Let's assume that the total purchase made by Amanda is $200.

In this case, she uses her credit card to make payment for $75. Therefore to know the remaining balance, you'll subtract $75 from the total purchase. This will be:

= $200 - $75

= $125
