Given:
We are asked to evaluate the given expression.
Explanation:
Since the number you are taking away is greater than thenumber that you want to taake it away from, we have to swap the numbers and then the result will be a negative number.
Therefore, the correct answer is -3.64
Answers:
- 7: 20 miles
- 8: 28 miles
- 9: 1 error
- 10: Their speed is 50
- 11: 365 words in 5 mins
Step-by-step explanation:
- #7 and #8
Our equation is: With f meaning "fare" (price) and m meaning "miles".
Question 7 - Juan's fare for his ride costs $6.05. We must solve for .
Step 1. Substitute - <em>Substitute the fare for in the equation.</em>
Step 2. Simplify/Solve - Solve for .
<em>- Distribute</em>
<em>- Subtract 0.2 from 2.25</em>
<em>- Subtract -2.05 from 6.05</em>
<em>- Divide both sides by 0.2</em>
<u>And you have your answer of 20 miles.</u>
Question 8 - Same equation, different fare.
Step 1. Substitute
Step 2. Solve
And like so, we have
- Questions 9 - 11
<em>The equation given is . S = typing speed, w = words per 5 mins, and e= errors.</em>
Question 9 -
<em>We are given this information: S = 55, W = 285. We are solving for e</em>.
Substitute -
Solve -
So they would make 1 error.
Question 10 -
<em>Information given: 300 = w, 5=e. We are solving for S</em>
Substitute -
Solve -
Their speed is 50.
Question 11 -
<em>Information given: S = 65, e = 4. We are solving for w.</em>
Substitute -
Solve -
So w = 365.
