What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The expression for the inequality will be;
⇒ 3(8 – 4x) < 6(x – 5)
Now, Solve the inequality as;
The expression for the inequality will be;
= 3(8 – 4x) < 6(x – 5)
Divide by 3 both side,
= 8 - 4x < 2 (x - 5)
= 8 - 4x < 2x - 10
Add 4x both side;
= 8 - 4x + 4x < 2x - 10 + 4x
= 8 < 6x - 10
Add 10 both side;
= 18 < 6x
Divide 6 both side;

Step-by-step explanation:
13. x³ = 54
x = ∛4
Factor 54: 2 x 27
∛54 = ∛2 x ∛27

x = ∛88
88 = 8 x 11
∛88 = ∛8 x ∛11 = 2∛11
16. x³ = -128 means x has to be negative

For every 500 g of reactants, 3.1 g of catalyst were required. How much catalyst was
required for 900 g of reactants?
Answers
For every 500 g of reactants, 3.1 g of catalyst were required. The catalyst that was required for 900 g of reactant was 5.58g
What do you mean by a catalyst?The process of catalysis involves introducing a catalyst to chemical reaction to speed up the process. Catalysts are not destroyed during reaction and are unaffected by it. Very little amounts of catalyst are frequently sufficient when the reaction is swift and the catalyst recycles quickly; the velocity of the reaction is greatly influenced by mixing, surface area, and temperature. In most cases, catalysts interact with one or more reactants to produce intermediates that ultimately lead to the final reaction product, regenerating the catalyst in the process.
Homogeneous catalysis, in which all of the components are dispersed in the same phase as the reactant (often a gas or liquid), and heterogeneous catalysis, in which the components are not. It's common to think of enzymes and other biocatalysts as a a third category.
In all branches of the chemical business, catalysis is commonplace. 90% of all chemical compounds manufactured for commercial purposes are thought to use catalysts at some point during the manufacturing process.
500g of reactants = 3.1g of catalyst
1g of reactants = 3.1g of catalyst / 500g of reactants
900g of reactants = [tex]\frac{3.1}{500} * 900[/tex] = 5.58g

What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.
From the diagram:
∠J + ∠K + ∠L = 180° (angles in a triangle)
Substituting:
(7x + 2) + (8x) + (4x + 7) = 180
19x + 9 = 180
x = 9
∠J = 7x + 2 = 7(9) + 2 = 65°

What is algebraic identities?In mathematics, an identical element, also known as a neutral element, is an element of a set that, when subjected to a binary operation, leaves each element of the set intact. In algebraic structures like groups and rings, this idea is applied. Algebraic identities are algebraic equations that are true regardless of the value of each variable. Additionally, they are employed in the factorization of polynomials. Algebraic identities are employed in this manner for the computation of algebraic expressions and the solution of various polynomials.
Given Data
m + n+ p= 10
mn + np + mp = 27
For m² + n²+ p²
Using algebraic identities,
(m+ n +p)² = m² + n² + p² +2(mn + np + pm)
(10)² = m² +n² + p² + 2(27)
100 = m² + n² + p² + 54
100 - 54 = m² + n² + p²
46 = m²+n²+p²

What is the special angle pair relationship between 2 and 3?
Answers
The special angle pair relationship between ∠2 and ∠3 is same-side interior angles.
How to find angles?When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, linear angles, vertically opposite angles etc.
Therefore, the angle pair relationship between angle 2 and 3 are same side interior angles.
The same-side interior angle theorem states that when two lines that are parallel are intersected by a transversal line, the same-side interior angles that are formed are supplementary.
Supplementary angles are those angles that sum up to 180 degrees. In other words, If the measures of two angles sum up to 180°, they are called supplementary angles.
Therefore, same side interior angles are supplementary angles.

What is a tubing?The entire family can participate in tubing. Change into swimwear, rent a tube and a life jacket, and float down the river—that it's easy. Numerous outfitters provide transportation to the best waterways and rent tubes from Blue Ridge to Columbus, via Helen and Columbus.
The total cost of rent on tube = $360
Price of regular tube = $15
Price of cooler tubes = $7.5
Let the no. of regular tubes be and cooler tubes be y
The equation forms
15x + 7.5y = 360 ...1
As we can notice regular tube is twice the price of cooler tubes, sthe the equation forms
2(7.5) = 15
This means when y = 2, x = 1
cross multiply them and we find
2/y = 1/x
x/y = 1/2
x = y/2 ...2
Putting the value of x in eq 1, we get
15(y)/2 + 7.5y = 360
7.5y + 7.5y = 370
15y = 360
y = 360/15
y = 24
Putting the value of y in eq 1, we get
15x + 7.5(24) = 360
15x + 180 = 360
15x = 360 - 180
15x = 180
x = 180/15
x = 12
Thus, The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24.
