Step-by-step explanation:
For 15 points.Explain, in your own words, the steps necessary to solve a system of equations
using the substitution method.
First, what is an equation?
➳ A mathematical statement which shows that two algebraic expressions are equal is called and equation.
Or, LHS = RHS
Example:- 3x - 5 = x + 8
An equation is said to be a linear equation if it contains only one variable (literal) with highest power 1.
_______________________
Solving an equation:-
To solve the equation x + 5 = 7 means to find the value of an unknown algebraic quantity used in the equation.
Example:-
To solve the equation x + 5 = 7 means to find the value of x.To solve the equation 3y + 2 = 9 means to find the value of y.To solve the equation [tex]\sf \dfrac{2a}{3} + 4 = 10[/tex] means to find the value of a ⠀⠀⠀⠀⠀⠀and so on!⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
★ Rules for solving an equation by the substitution method:-
Rule ❶
If x = 2, the value of the expression 3x + 2 = 3 × 2 + 2 = 6 + 2 = 8
Rule ❷
If x = 0, the value of the expression 3x + 2 = 3 × 0 + 2 = 0 + 2 = 2
Rule ❸
If x = -2, the value of the expression 3x + 2 = 3 × -2 + 2 = -6 + 2 = -4
Now consider the algebraic expression 5x - 2y
This expression consists of variables x and y.
Now if :-
x = 3 and y = 2, 5x - 2y = 5 × 3 2 × 2 = 15 - 4 = 11x = 8 and y = 5, 5x - 2y = 5 × 8 - 2 × 5 = 40 - 10 = 30⠀⠀⠀⠀⠀⠀⠀⠀
The process of finding the value of an algebraic expression by substituting the given value of its variable is called substitution.⠀⠀

Seventy-five percent of the medium-sized companies doing business in
Brooklyn provide their CEO's with desktop computers. Moreover, 30% of
these companies provide a laptop given they have provided a desktop. What
is the probability that a CEO gets a desktop and a laptop?
Please help me out!
Answer:9/40
Step-by-step explanation: Multiply probability of getting desktop by probability of getting laptop. 3/4 (desktop)* 3/10 (laptop)=9/40(desktop &laptop) . That fraction can't be reduced and is equal to .225 or 22.5%

387 is rounded to 400
Step-by-step explanation:
Answer:
400
Step-by-step explanation:
0-49 = round down
50-99 = round up
Since 718 is between 0-49, we would round to 700
Since 331 is between 0-49, we would round to 300
700 - 300 = 400
If you randomly select a card from a well-shuffled standard deck of 52 cards, determine the probability that the card you
select is a 6.
a) Write your answer as a reduced fraction.
b) Write your answer as a decimal, rounded to the nearest thousandth.
c) Write your answer as a percent. Round to the nearest tenth of a percent as needed.
Answer:
a. 1/13
b. 0.077
c. 7.7
Step-by-step explanation:
a. there are 4 of the 6 in a deck of cards so the probability of taking this cards from the deck of 52 cards is 4/52. Given you 1/13.
Probability is the chance of an event to occur from a total number of outcomes.
The answer in the reduced fraction is 1/13
The answer in decimal is 0.077
The answer as a percentage is 7.7 %
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of cards = 52
The number of cards randomly selected = 1
The number of cards that is 6 in a deck of 52 cards:
= 4
i.e
6 of spade
6 of diamond
6 of hearts
6 of club
Now,
The probability that a randomly selected card from a deck of
52 cards is 6:
= Number of cards that is 6 / Total number of cards
= 4 /52
The answer in the reduced fraction of 4/52 is 1/13
The answer in decimal:
= 4/52
= 0.0769
Rounding to its nearest thousandth.
= 0.077
The answer as a percent:
= 4/52 x 100
= 0.0769 x 100
= 7.69 %
Rounding to the nearest tenth.
= 7.7 %
Thus,
The answer in the reduced fraction is 1/13
The answer in decimal is 0.077
The answer as a percentage is 7.7 %

Wesley has a baseball sticker with a radius of 2.3 centimeters. Determine the circumference of his baseball sticker to the nearest tenth of a centimeter.
Answer:
14.4 centimeters
Step-by-step explanation:
The formula for circumference is: [tex]2\pi r[/tex]. In this case, the r (radius) is 2.3. Multiply it by 2 to get the diameter or 4.6. Then multiply 4.6 x [tex]\pi[/tex] (pi) to get 14.444. This rounded to the nearest tenth of a centimeter is 14.4.

Aiden earned $50 in interest in six
months. If his savings account has a
rate of 5%, how much did Aiden
start with in his account?
9514 1404 393
Answer:
$2000
Step-by-step explanation:
The amount of interest is given by the formula ...
I = Prt
where P is the principal invested, r is the annual rate, and t is the number of years. Here, we want to find P when I = 50, r = 0.05, and t = 1/2.
50 = P(0.05)(1/2)
P = 50/(0.05·1/2) = 2000

An oblique cylinder has a radius of 16 meters and a volume of 5,120(pi) cubic meters. Use Cavalieri’s Principle to solve for the height of the solid.
20 meters
25 meters
50 meters
250 meters
Answer: 20 meters
Step-by-step explanation:
We are told that an oblique cylinder has a radius of 16 meters and a volume of 5,120 pi cubic meters. We will use volume of oblique cylinder to find the height of our given cylinder. volume of a oblique cylinder= πr²hUpon substituting our given values in above formula we will get,5,120π m³ = π ( 16 m² × h )
5,120π m³ = π × 256 m² × h
Let us divide both sides of our equation by 100 pi.Therefore, height of our given oblique cylinder is 20 meters.

The angle of elevation from a park bench 724 feet from the base of the Gateway Arch in St. Louis, Missouri is 22°. How tall is the Gateway Arch, rounded to the nearest whole number?
Answer:
Gateway Arch is [tex]292.46[/tex] feet tall
Step-by-step explanation:
As we know,
the horizontal distance from the gate of the Arch to the bench [tex]= 724[/tex] feet
The angle of elevation is [tex]22[/tex] degree
Let H be the height of the gate be "H"
Tanθ= Perpendicular/Base
Substituting the given values in above equation, we get -
[tex]tan 22 = \frac{H}{724} \\H = 724 * tan 22\\H = 724 * 0.404\\H = 292.46[/tex]feet

Step-by-step explanation:
Hardcover Books = $18.25 each
Softcover Books = $5 each
She bought 2 hardcover and 2 softcover.
Hardcover: $18.25 + $18.25 = $36.50
We already know what 2 softcover books cost ($10)

Answer:
b
Step-by-step explanation:
The slope of b is 5.5 whereas the slope for the other three graphs are 5, so B is different from the rest.
A. (4, 0.8), so by rise over run, the slope is 4/0.8=5.
B. (55, 10), so 55/10=5.5.
C. (20, 4), so 20/4=5.
D. (50, 10), so 50/10=5.
Since B is the only graph with a slope of 5.5 and the other graphs have a slope of 5, the answer is B.

What is the Venn diagram?A Venn diagram is a diagram that helps us visualize the logical relationship between sets and their elements and helps us solve examples based on these sets. A Venn diagram typically uses intersecting and non-intersecting circles (although other closed figures like squares may be used) to denote the relationship between sets.
Let Math=M, Science=S and English=E
n(M)+n(S)+n(E)=1/2 (n(M∩S)+n(S∩E)+n(E∩M)
Let the number of students who study only one subject be x.
Let the number of students who study only two subjects be x/2.
n(M∩S∩E)=20
n(M∩S)+n(S∩E)+n(E∩M)=80
∪=x/2+80
∪=x+ x/2+20
Now, x/2+80 = x+ x/2+20
⇒ x=60
So, ∪=x/2+80 =110
Therefore, the total number of students in the survey is 110 students.
