This is very similar to solving linear equations except for one thing, If we multiply or divide by a negative number, we must flip the inequality sign.
<h3>What is linear inequality?</h3>
In mathematics, inequality occurs when a non-equal comparison is made between two mathematical expressions or two numbers. In general, inequalities can be either numerical inequality or algebraic inequality or a combination of both.
To better understand it, let's examine the example.
2x - 5 < 3
So, when we solve, let's just consider the inequality sign like a regular equal sign.
Let's start by adding 5 to each sides.
2x - 5 + 5 < 3 + 5
To find the value of x , we must divide it by two.
2x/2 <8/2
And the final result is x= 4.
This is our answer.
So if we need to graph it, let’s draw a number line and draw an open circle at 4. Open circle because x is not equal to 4. Then make an arrow going to the left.

Answer:
1.80 in^3
1.0 fluid ounces^3
Step-by-step explanation:
volume of a cone = 1/3 πr²h
π = 3.14
r = 2.2 / 2 = 1.1
h = the value of h can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
1.8² = 1.1² + b²
3.24 = 1.21 + b²
3.24 - 1.21 = b²
2.03
b = √2.03 = 1.42
Volume = 1/3 x 3.14 x 1.21 x 1.42 = 1.80 in^3
1.80 x 0.554 = 1.0 fluid ounces^3
Answer:
-8
Step-by-step explanation:
(x-3y=136) + (18x+3y=288) We collect both processes to make y's disappear
19x=-152
x=-8
Answer:
-7
Step-by-step explanation:
-20 × -7 = 140
140 × -7 = -980
Answer:
4200
Step-by-step explanation:
4280=(?)+80
So the answer is 4200
