Answers:

7:    20 miles8:    28 miles9:   1 error10:   Their speed is 5011:   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 - Substitute the fare for in the equation.

Step 2. Simplify/Solve - Solve for .

- Distribute

- Subtract 0.2 from 2.25

- Subtract -2.05 from 6.05

- Divide both sides by 0.2

And you have your answer of 20 miles.

Question 8 - Same equation, different fare.

Step 1. Substitute

Step 2. Solve

And like so, we have

Questions 9 - 11

The equation given is . S =  typing speed, w = words per 5 mins, and e= errors.

Question 9 -

We are given this information: S = 55, W  = 285. We are solving for e.

Substitute -

Solve -

So they would make 1 error.

Question 10 -

Information given: 300 = w, 5=e. We are solving for S

Substitute -

Solve -

Their speed is 50.

Question 11 -

Information given: S = 65, e = 4. We are solving for w.

Substitute -

Solve -

So w = 365.

Hoped this helped!~
