A system of equations in slope-intercept form can be solved by,
D. Graphing and substitution are appropriate to use if the answer involves integer values. If the answer involves values that are not integers, the substitution would be more efficient because an exact answer can be obtained. It can be difficult to read graphs if the intersection point does not have integer values so this would be an inefficient method to solve with.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, a system of equations in slope-intercept form y₁ = m₁x₁ + b₁ and
y₂ = m₂x₂ + b₂.
We can use both substitution and graphing depending on the numerical values of the variables.
If the solution involves integer numbers, graphing and substitution are the proper methods to utilize. Substitution would be more effective since an accurate solution may be reached if the solution involves values that are not integers. If the intersection point doesn't have integer values, it can be challenging to understand graphs, so using this approach to solve would be ineffective.

1 cm/10 mm = 12.5 cm/x
10 mm/1 cm= x/140 mm
Answer:

A.5n-100
B.5n+100
C.100-5n
D.100 divided by 5n
The expression represents the profit if n tickets are sold is 100-5n, the correct option is A.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Given;
They charge $5.00 a ticket to attend the event.
The rental fee for the auditorium is $100
Now,
5*n is the charge collected
100 is the rent
=5n-100
Therefore, by algebra profit will be 5n-100.

Edelia is planning a crawfish broil party. Each case of crawfish weighs 20 pounds of crawfish. If each pound of crawfish contains 15-25 individual crawfish, approximately how many crawfish can she serve if she buys 5 cases?
Edelia can serve approximately 1,500 to 2,500 crawfish if she buys 5 cases.
Given:
Each case of crawfish weighs 20 pounds.Each pound of crawfish contains 15-25 individual crawfish.Edelia buys 5 cases.The theory of unit conversion and basic arithmetic is used to solve this question.
1. Finding the total weight of crawfish.
Total weight of crawfish = Weight per case × Number of cases
Total weight of crawfish = 20 pounds × 5 cases
Total weight of crawfish = 100 pounds.
2. Determining the range of crawfish count.
Since each pound of crawfish contains 15-25 crawfish, we can calculate the minimum and maximum number of crawfish as follows:
Minimum crawfish count = Minimum crawfish per pound × Total weight of crawfish
Minimum crawfish count = 15 crawfish/pound × 100 pounds
Minimum crawfish count = 1500 crawfish.
Maximum crawfish count = Maximum crawfish per pound × Total weight of crawfish
Maximum crawfish count = 25 crawfish/pound × 100 pounds
Maximum crawfish count = 2500 crawfish.
Therefore, Edelia can serve approximately 1,500 to 2,500 crawfish if she buys 5 cases of crawfish.
