Answer:
D
Step-by-step explanation:
So we have the expression:

First, simplify. Two negatives make a positive. Therefore, the -(-7) turns into +7:

When adding on the number line, we move to the right.
Therefore, the correct interpretation is the value 7 digits to the <em>right</em> of -4.
D is the correct answer.
Answer:
<em>Answer: A'Reana's weekly allowance is $100</em>
Step-by-step explanation:
<u>Backward Solution</u>
To solve some problems, we can work backward, using the inverse operations, to arrive at the solution.
The problem explains a sequence of expenses A'Reana does with her weekly allowance. In the end, she had $37.50.
That final balance came when she last spent $7.50 on a pizza. Thus, before that, she had $37.50+$7.50=$45
This balance is half of her previously remaining money. The other half was spent on a new shirt. Thus she had 2*$45=$90.
Those $90 were left after she gave $10 to her friend Taylor, thus, the initial money was $90+$10 = $100
Answer: A'Reana's weekly allowance is $100
Answer: 
Step-by-step explanation:
Given the following equation:

You can follow these steps in order to solve for "x" and find its value:
1. Apply Distributive property on the right side of the equation:

2. Subract
from both sides and add the like terms:

3. Subtract 1.8 from both sides:

4. Finally, divide both side of the equation by -1.5:

Answer:
15
Step-by-step explanation:
A(n)=3+2(n-1)
