Step-by-step explanation:
3x+y=1
15x+5y=5
Step: Solve3x+y=1 for y:
3x + y +−3 x = 1 + −3x (Add -3x to both sides)
y=−3x+1
Step: Substitute−3x+1 for y in 15x+5y=5:
15x+5y=5
15x+5(−3x+1)=5
5=5(Simplify both sides of the equation)
5+−5=5+−5(Add -5 to both sides)
0=0
so there are infinite solutions

The number line which represents the solutions that is n > -3 is number line 1.
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality.
Any real number can be represented in two dimensions using a number line. Any number on the number line with a solid circle next to it refers to include that number followed by the rest of the values, and any number with a hollow circle refers to exclude that value from the list before the rest of the values.
The solutions represented by number line 1 are those where: n > -3.
Using special techniques, number lines are used to represent real numbers. It was Illustrated in number line 1.

The Science Club went on a two-day field trip. The first day the members paid $40 for transportation plus $19 per ticket to the planetarium. The second day they paid $90 for transportation plus $16 per ticket to the geology museum. Write an expression to represent the total cost for two days for the n members of the club.
Answers
Answer:
total cost = $130 + $35n
Step-by-step explanation:
Cost incurred on the first day.
Fixed cost = $40. this amount is fixed because it does not depend on the number of students that take the trip
variable cost = $19n. It is variable because it depends on the number of students that take the trip. the more the club members that take the trip, the higher the cost
Total cost on the first day = $40 + $19n
Cost incurred on the second day
Fixed cost = $90. this amount is fixed because it does not depend on the number of students that take the trip
variable cost = $16n. It is variable because it depends on the number of students that take the trip. the more the club members that take the trip, the higher the cost
Total cost on the second day = $90 + $16n
Total cost incurred would be the sum of the two costs incurred on the two days
total cost = $40 + $19n + $90 + $16n
= $130 + $35n
A student earned a grade of 80% on a math test. He answered 20 of the questions correctly. How many problems were on the test?
Answers
Answer: 25
Step-by-step explanation:
Given
The student earned 80% on a math test
The student answered 20 questions
Suppose x is the total no of questions
So, we can write
[tex]\Rightarrow \dfrac{20}{x}\times 100=80\%\\\Rightarrow \dfrac{20}{x}=0.8\\\\\Rightarrow \dfrac{20}{0.8}=x\\\\\Rightarrow x=25[/tex]
So, there are 25 questions in total

in isosceles trapezoid EFGH, FG parallel EH, FG=10, GH=12, and ∠E=60. Find the area of EFGH.
Answers
Answer:
22√3 units squared
Step-by-step explanation:
1) Draw the trapezoid
2) Notice you have to find the height to find the area of the trapezoid
3) Notice it is a 30 60 90 triangle when you draw the line to find the height
4) Solve for the 30 60 90 triangle and you get the height to be 2√3
5) Solve for the area of the trapezoid using this formula A= 1/2 h ( b1 + b2)
6) Fill in the numbers for the equation A= 1/2∙ 2√3 ( 10 + 12)
7) Keep aside the 1/2 for now
8) Simplify equation 2√3 + 22 or 2√3 + (10 + 12)
9) Simplify further 44√3
10) Now bring back the 1/2 and put it in the equation 1/2∙ 44√3
11) Simplify to get 22√3
12) 22√3 is the area of the trapezoid
13) 22√3 units squared is the final answer
I will put a my drawing of the trapezoid for reference and this is what I used to solve the question.
If you want to know how I solved the 30 60 90 triangle please let me know.

What is m CD ?
Plzz help
Answers
Given:
Arc(AB) = 78 degrees
Measure of angle CMD = 106 degrees
To find:
The measure of arc CD.
Solution:
Secant intersection theorem: If two secant of a circle intersect each other inside the circle, then the intersection angle is the average of intercepted arcs.
Using secant intersection theorem, we get
[tex]m\angle CMD=\dfrac{1}{2}(Arc(AB)+Arc(CD))[/tex]
[tex]106^\circ=\dfrac{1}{2}(78^\circ+Arc(CD))[/tex]
Multiply both sides by 2.
[tex]212^\circ=78^\circ+Arc(CD)[/tex]
[tex]212^\circ-78^\circ=Arc(CD)[/tex]
[tex]134^\circ=Arc(CD)[/tex]
Therefore, the measure of arc CD is 134 degrees and the correct option is C.
