You substitute in an expression by filling in the desired and accustomed unknown value to the value you're trying to find. An example below can better elaborate what I want to say above. In the equation below, 7 - 2n = 5 the unknown is represented by n moreover, the equation suggest to find the missing to make it equilateral on both sides.
In mathematical expression, the equation then becomes 7 - 2n = 5
The next procedure is to find the unknown.
1. 7 - 2n = 5
2. -2n = 5 - 7
3. -2n = -2
4. n = -2/-2
5. n = 1
Check:
Substitute n = 1
7 - 2 (1) = 5
7-2 = 5
5=5
Answer:
96 miles
Step-by-step explanation:
3 multiplied by what gives you 24?
8 right?
So, what you want to do is 8 multiplied by 12.
Doing so you will reach the conclusion that 12 multiplied by 8 equals 96.
So you can go 96 miles on a speedboat with 12 gallons of gas.
I hope this helped you :)

Step-by-step explanation:
A scenario that would best model the graph on Holly, her home, and school is:
- Holly was trying to get to school from home but fell ill when 4 miles from home.
- Holly waited to catch her breath and gain some strength.
- Holly reached school and reported her condition.
- The school allowed her to go home.
<h3>What happened Holly's journey to school?</h3>
As Holly was heading to school, she felt uneasy and had to wait for 10 mins to catch her breath.
After doing so, she then continued to school which was 6 miles from her home. When she got there, she went to the nurse's office.
She waited in school for 15 minutes and was then told to go home to rest and recuperate. She then made the journey back home in a car and arrived in 10 minutes.
