Question: Mai had $14.50. She spent $4.35 at the snack bar and $5.25 at the arcade. What is the exact amount of money Mai has left?
Answer: $4.90
Steps: Step 1: Find operation: The operation in this problem is subtraction because words such as "spent" means that she used money, meaning we subtract.
Step 2: Figure out order of numbers: Now that we know that the operation is subtraction, we need to know what numbers to subtract. The problem says that Mai had $14.50, which means that this is the total amount of money she had when she started. Spent means that Mai used money, so this means that we subtract like this: $14.50-$4.35-$5.25.
Step 3: Subtract: Now that we know what operation to use, and what order to use the numbers, we can finish the problem:
<h2>
$14.90</h2><h2>
- $ 4.35</h2><h2>

$10.15</h2><h2>
- $ 5.25</h2><h2>

Question: Kristina rides her bicycle 384.25 miles over 29 weeks to and from her job. How many miles does she ride each week to and from her job if she rides the same amount each week?
Answer: 13.25
Steps: 1: Find operation: To solve this question, we need to find the operation. Words such as "same amount each week" mean that this is division.
Step 2: Figure out order of numbers: Now, we need to figure out what to divide by. We divide 384.25 by 29 because it say that she rides 384.25 miles over 29 weeks.
Step 3: Divide: Now, we will solve the equation: 384.25 divided by 29 is 13.25, so the answer is 13.25.
Hope this helps you!
P.s. Sorry I could not show how to divide 384.25 by 29.

Answer:
Step-by-step explanation:
In representing mixed numbers on a number line, we need first to pay attention to the denominators. Here, denominators are 8 and 5, their least common multiple is 40, so, we will need to cut up space between two numbers on the number line on 40 pieces. Also, we have 5 and 3 wholes at these mixed numbers, so, our answer is going to be greater than 8.
We will cut the space between 8 and 9 on a number line on 40 pieces, and we will add 
and 
and get :
So, on a number line between 8 and 9 we need to count 31 out of 40 pieces and that is the result, 8 wholes and 
.
Answer:
pretty sure its 55° because the total should be 180* and I know that C is a right angle aka 90° and 90 + 35 = 125 and 180-125=55
Here we want to analyze the given graph.
The answers are:
a) for 500 messages the cost is $30 and for 1800 messages the cost is $80.
b) It means that for 1400 messages the cost is $60.
c) Because there is a fixed cost for the first 800 messages.
<em>Let's expand more on each solution.</em>
First, remember that the horizontal axis represents the number of text messages end in hundreds, while the vertical axis represents the cost in dollars.
a) We want to find the cost for 500 texts and 1800 texts.
To find the cost for 500 texts, you need to <u>count 5 squares on the horizontal axis</u>, and then see where the graph intersects the vertical axis for that value.
We can see that:
f(500) = $30
We do the same for 1800 (this time you count 18 squares), then we get:
f(1800) = $80
b) f(1400) = 60
This would mean that <u>the </u><u>cost </u><u>of 1400 text messages is</u><u> 60 dollars.</u>
c) Assume that for the first 800 text messages you have a fixed cost, and after that the company starts to charge an extra for each message you send, this is why we would have a linear increase after the message number 800.
