There are a total of 64 students in a drama club and a yearbook club. The drama club has 10 more students than the yearbook club. Write a system of linear equations that represents this situation. Let x represent the number of students in the drama club and y represent the number of students in the yearbook club. How many students are in the drama club? The yearbook club?
Answer: There are 37 students in the drama club and 27 students in the drama club.
Step-by-step explanation:
Let x= number of students in the drama club.
y= number of students in the yearbook club.
As per given, we have
x+y=64
x=10+y
A system of linear equations that represents this situation:
x+y=64 (i)
x=10+y (ii)
Put value of x from (ii) in (i)
10+y+y=64
⇒ 2y= 54
⇒ y = 27 [Divide both sides by 2]
Put value of y in (ii) , we get
x= 10+27 = 37
Hence, there are 37 students in the drama club and 27 students in the drama club.

In the equation 15y - 3 = 25 what vocabulary word can be best used to describe 15y - 3in the context?
Answer:
3 less than the product of a number and 15
Step-by-step explanation:
Given the expression
15y - 3 = 25
The unknown variable is y. Rewriting 15y - 3 as a statement
15y means the product of a number and 15
15y - 3 means 3 less than the product of a number and 15
Hence vocabulary word that can be best used to describe 15y - 3 is 3 less than the product of a number and 15

Solve for x:
4(x + 4) = 6(x - 2)
O A. x = 9
B. x = 14
O C. x = 8
D. x = 1
Answer:
x = 14
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASAlgebra I
Equality PropertiesStep-by-step explanation:
Step 1: Define equation
4(x + 4) = 6(x - 2)
Step 2: Solve for x
Distribute: 4x + 16 = 6x - 12Subtract 4x on both sides: 16 = 2x - 12Add 12 on both sides: 28 = 2xDivide 2 on both sides: 14 = xRewrite: x = 14Step 3: Check
Plug in x to verify it's a solution.
Substitute: 4(14 + 4) = 6(14 - 2)Add/Subtract: 4(18) = 6(12)Multiply: 72 = 72And we have our final answer!
Answer: 14 = x
Step-by-step explanation: Start by distributing through the parenthses
on each side of the equation to get 4x + 16 = 6x - 12.
Now move your x's to the right and numbers
to the left and you get 28 = 2x.
Divide both sides by 2 and 14 = x.
Brian orders a center pivot irrigation system to water his field system is made up of a line connected pipes that turn around a center point Brian system will be 1000 150 feet long what is the longest distance across the space the system still water show your work
Answer:
2,300
Step-by-step explanation:
since it turns it would be double and both radius would be 1,150ft you have to add them together and then you get 2,300ft.
The longest distance across the space the system still water is the diameter of the circle, that is 2300 feet and this can be determined by using the given data.
Given :
Brian orders a center pivot irrigation system to water his field system is made up of a line connected pipes that turn around a center point.Brian's system will be 1150 feet long.The following steps can be used in order to determine the longest distance across the space the system still water:
Step 1 - According to the given data, the Brian system will be 1150 feet long.
Step 2 - So, from the given data it can be concluded that the irrigation system moves about a point and form a circle whose radius is 1150 feet.
Step 3 - So, the longest distance across the space the system still water is the diameter of the circle, that is:

3) Z3 and Z6 are supplementary
4) Z1 and 25 are supplementary
Answer: D, m<5=55.1 and m<7=124.9
Step-by-step explanation: 5 is the opposite of 4 in this diagram becuase of the bisector so that would make it the same 55.1, while 7 is an obtuse angle so it's clearly more than 90°, leaving 124.9 the most logical explanation.
Statement, ∠3 and ∠6 are supplementary will always be used if lines AB and CD are parallel.
What is a traversal line?When a line passes through two lines on the same plane, is called traversal line.
Given that,
Two lines are AB and CD,
Also, a transversal line EF intersect line AB and CD.
According to traversal line property,
If two lines are parallel and a traversal line intersect two lines, then each pair of interior angles on the same side of the transversal is supplementary.
In the given figure, Angle 3 and 6 are interior angles
Implies that,
Angle 3 and angle 6 will be supplementary if line AB and CD are parallel.
Hence, statement ∠3 and ∠6 are supplementary shows that lines AB and CD are parallel.

the side length of a square can be expressed as 2x+3. If the area of the square is 121 square meters, what is the value of x?
Answer:
x=4
Step-by-step explanation:
(2x+3)^2=121
2x+3=square root of 121
2x+3=11
2x=11-3
2x=8
x=4
(in a square all sides are equal therefore area =length ×width where length and width=2x+3)

3. Charlie needs to hire a plumber to fix his kitchen sink. ABC Plumbing charges a flat
fee of $50 plus 535 per hour, Pipes R Us charges a flat fee of $75 and $25 per hour.
How many hours will the two companies charge for the total cost to be equal?
Answer:
2 hoursStep-by-step explanation:
step one:
given
ABC Plumbing charges
flat fee=$50
charge per hour= $35------------------i want to assume you meant $35 and not $535
Pipes R Us charges
flat fee=$75
charge per hour= $25
Let the number of hours be x
the equation for the charges is given bellow
y=35x+50----------1
y=25x+75-----------2
equating 1 and 2
35x+50=25x+75
35x-25x=75-50
10x=20
divide both sides by 10
x=20/10
x=2 hours

The nth term of an AP is 12-4n. Find the first term and the common difference.
Answer:
the first term is 8 and common difference d is -4.
Step-by-step explanation:
We are given nth term of an arithmetic sequence is: aₙ=12-4n
We need to find first term and common difference of given arithmetic sequence
First term can be found by putting n=1:
[tex]a_n=12-4n\\a_1=12-4(1)\\a_1=12-4\\a_1=8[/tex]
So, first term is a₁= 8
Now to find common difference we need to find second term
Second term can be found by putting n=2
[tex]a_n=12-4n\\a_2=12-4(2)\\a_2=12-8\\a_2=4[/tex]
So, second term is: 4
The common difference is found by subtracting second term with first term: a₂-a₁= 4-8 = -4
So, first term is 8 and common difference d is -4

−6a+6+3a=−3a+3+3a(Add 3a to both sides)
−3a+6=3
−3a+6−6=3−6(Subtract 6 from both sides)
