Answer:
Ted is correct. Maggie made mistakes while trying to isolate x for both equations.
Step-by-step explanation:
For 3x-2=0, in order to move -2 to the left side, Maggie had to add 2 on both sides because -2+2=0. The same problem is seen for x+5=0. Maggie had to subtract 5 on both sides because +5-5=0
Answer:
No
1/5 is equivalent to 2/10
Answers:
Step-by-step explanation:
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 
<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.
Answer:
1. 14
2. 22
3. 3
4. 14
5. 10
6. 15
Step-by-step explanation:
1. 20-6=14
2. 22 bc it just is
3. 15-12
4. 16-2
5. 10+4
6. 5+10 is 15
This was too easy. Are these supposed to be trick questions.
