The test contains 10 three-point questions and 14 five-point questions.
Step-by-step explanation:
We can substitute a definition of one of the variables by rearranging the first equation.
We set the first equation equal to one of our two variables.
[tex]y = 24 - x[/tex]
Now we substitute this equality into our second equation
[tex]3x + 5(24 - x) = 100[/tex]

One year, the population of a city was 397,000. Several years later it was 412,880.
Find the percent increase.
The percentage increase from the initial population of 397,000 to 412,880 is 4%
How to determine the percentage increase?From the question, we have the following numbers:
397,000 and 412,880.
The numbers are increments from 397,000 to 412,880.
The percentage increase is calculated as:
%Percentage = (Old number - New number)/Old Number
Substitute the numbers in the above equation
%Percentage = (412880 - 397000)/397000
Evaluate the difference
%Percentage = 15880/397000
Evaluate the quotient
%Percentage = 0.04
Express 0.04 as percentage
%Percentage = 4%
Hence, the percentage increase from the initial population of 397,000 to 412,880 is 4%

Cody purchased a car for $4500 that will depreciate 28% a year. Write an exponential growth/decay equation that represents the value of Cody's car overtime. How much will the car be worth in 15 years? Round to the nearest cent.
Answer:
$32.60
Step-by-step explanation:
This question has to to do with exponential decay. The formula is given as:
y = a(1 - r)^x
y = Value of the material after x years
a = Initial value of the material
x = Time in years
r = rate of depreciation or decay
Therefore,
y = 4500 × (1 - 0.28)¹⁵
y = 4500 × 0.72¹⁵
y = $32.598675906
y = Approximately = $32.60
Therefore the of the car after 15 years = $32.60
The sum of 85 + w is less than or equal to 6 multiplied by y.
A. 85 + w ≤ 6y
B. 85 + w ≥ 6y
C. 6 x y ≤ 85 + w
D. 85 + w ≠ 6y
Given:
The sum of 85 + w is less than or equal to 6 multiplied by y.
To find:
The inequality for the given situation.
Solution:
We know that,
The sum of 85 and w means "85+w".
Less than or equal means "≤".
6 multiplied by y means "6y".
So, the inequality for the statement "the sum of 85 + w is less than or equal to 6 multiplied by y", is:
[tex]85+w\leq 6y[/tex]
Therefore, the correct option is A.

The population of Florida in 2000 was 15,982,378 and the land area was 54,252 square miles. The population increased 26.8% by 2015. To the nearest whole number, how much did the population density, in people per square mile, increase from 2000 to 2015?
Answer: See explanation
Step-by-step explanation:
Population in 2000 = 15,982,378
Land area = 54,252 square miles
The population density in 2000 will be:
= Population / Land area
= 15982378 / 54,252
= 294.60people per square miles
Since the population increased by 26.8% in 2015, the population in 2015 will be:
= 15,982,378 × (100% + 26.8%)
= 15,982,378 × 126.8%
= 15,982,378 × 1.268
= 20,265655
The population density in 2015 will be:
= Population / Land area
= 20,265655 / 54,252
= 373.55 people per square miles
The increase in population density from 2000 to 2015 will be:
= 373.55 - 294.60
= 78.95

Miss Allen read for 3/4 of an hour less than the student who read the most. How long sis Miss Allen read for?
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Allen = \frac{3}{4}hr[/tex] less than the most hour
Required
Hours read by Miss Allen
The question is incomplete, as the hours read by each student is not given.
To solve this, I will assume that the longest hours read by a student is x.
So, the expression for Miss Allen will be:
[tex]Allen = x - \frac{3}{4}hr[/tex]
Assume that [tex]x = 1hr[/tex]
The expression becomes
[tex]Allen = 1hr - \frac{3}{4}hr[/tex]
Take LCM and solve
[tex]Allen =\frac{4 - 3}{4}hr[/tex]
[tex]Allen =\frac{1}{4}hr[/tex]

A square piece of sheet metal is to be used to make a stop sign. each side of the sheet metal is 50cm long. A triangle will be cut off each corner, leaving a regular octagon. which pair of equations can be used to calculate the length of each side of the octagon
Answer:
L = a √( 4 + 2√2)
Step-by-step explanation:
L = a √( 4 + 2√2) is the equation which can be used to calculate the length of each side of the octagon. In the equation i.e. L = a √( 4 + 2√2), in which ''a'' is the length of each side of the octagon. So by putting of ''a'' we get the length of each side of the octagon. The octagon is regular means all of its sides and angles are congruent or similar to each other. Each angle in the octagon has a measure of 135 degrees.

How do I solve this problem?
========================================================
Explanation:
The notation [tex]a_1[/tex] refers to the first term. So the first term is 21.
The d = -3 is the common difference. It's the value we add onto any given term to get the next following term.
We can say:
second term = (first term) + (common difference)
second term = [tex]a_1 + d[/tex]
second term = 21 + (-3)
second term = 18
Through similar steps, you should find that the third term is 15, the fourth is 12, and so on. Each time we decrease by 3.
The arithmetic sequence would be: 21, 18, 15, 12, 9, ...
The first three terms are 21, 18, and 15.
