<h3>[Learning] How to solve a one-variable-inequality?</h3>
To solve a one-variable-inequality, isolate the variable on one side of the inequality. This can be done by using the <u>four mathematical operations.</u>
What is the four mathematical operations?
The<em> </em><u>four mathematical operations</u> include the following:
- Addition
- Subtraction
- Multiplication
- Division
These operations can be used to solve equations, inequalities, and more.
<h3>[Solving] Simplifying the inequality:</h3>
Given inequality:
As stated in the previous section, let's isolate the variable (c) using the four mathematical operations. Clearly, we have to add both sides by 12 of the inequality as "c" is being subtracted by 12. Therefore, we get:
- ⇒ c – 12 + 12 > –1 + 12
- ⇒ c > –1 + 12
Simplify the right-hand-side to obtain the simplified inequality:
Therefore, option B is the correct/best choice.

Louie’s location compared to his starting position is;
B: 3.35 miles
<h3>Calculation of Displacement</h3>
We are told that Louie ascended 6.75 miles up a mountain. Thus;
Displacement from present position is +6.75 miles.
Now, we are told that he descended 3.4 miles down the mountain. Thus, his new displacement relative to his original position is;
+6.75 - 3.4 = 3.35 miles

Answer:
Number of books she has not read =8
Step-by-step explanation:
Number of books Tara has=160
Number of books she has read =Percentage of what she has read x Number of book s she has =95% x 160=152
Number of books she has not read =Number of books Tara has- Number of books she has read=160-152=8
Answer:
Sam sokey 0.5 hours biking and 3.5 hours walking
Step-by-step explanation:
Here, we want to know the number of hours spent walking and biking
Mathematically; distance = speed * time
Let the number of hours spent walking be x and the number of hours spent biking be y
Mathematically;
x + y = 3 •••(i)
distance spent walking = 4 * x = 4x miles
distance spent biking = 12 * y = 12y miles
4x + 12y = 20
divide through by 2
2x + 6y = 10 ••••••(ii)
From i , x = 4-y
Substitute this into ii
2(4-y) + 6y = 10
8 - 2y + 6y = 10
8 + 4y = 10
4y = 10-8
4y = 2
y = 2/4 = 0.5 hours
The number of hours spent walking = 4-0.5 = 3.5 hours
Answer:
-2
Explanation:
f = -19.8
17.8 + -19.8 (f) = -2
