20x - 15 - 3x - 1 = 15x + 27 + 2x
17x - 16 = 17x + 27
17x - 17x = 27 + 16
0 = 43
Since zero is not equal to 43, this equation has no solution.

How many solutions does 3x – 1 = 3x + 1 have?
This system 3x – 1 = 3x + 1 has no solution.
How to solve the given system of equations?In order to determine the solution for the given system of equations, we would apply the substitution method. Based on the information provided above, we have the following system of equations:
y = 3x - 1 .......equation 1.
y = 3x + 1 .......equation 2.
By using the substitution method to substitute equation 2 into equation 1, we have the following:
3x - 1 = 3x + 1
3x - 3x = 1 + 1
0 = 2 (False).

A small town’s raffle has 85 entries and 3 gift baskets that three different people could win. What is the probability of winning a gift basket if you have 1 of the entries
Answer:
[tex]\dfrac{3}{85}[/tex]
Step-by-step explanation:
It is given that a small town’s raffle has 85 entries and 3 gift baskets that three different people could win.
Total number of entries = 85
Total number of gift baskets = 3
We need to find the probability of winning a gift basket.
[tex]\text{Required probability}=\dfrac{\text{Total number of gift baskets}}{\text{Total number of entries}}[/tex]
[tex]\text{required probability}=\dfrac{3}{85}[/tex]
Therefore, the required probability is [tex]\dfrac{3}{85}[/tex].

J is between H & K, if HJ=4t-15, JK=5t-6, and KH=15, find JK
Answer:
JK = 39
Step-by-step explanation:
HJ and JK are segments of line segment HK, so they must add up to the length of KH.
HJ + JK = HK
By substituting in the values of each line segment, we can solve for t.
(4t - 15) + (5t - 6) = 15
9t - 21 = 15
9t = 36
t = 9
Now that we have t, we can plug it in in order to find the value of JK.
JK = 5t - 6
5(9) - 6
45 - 6
39
JK = 39

Now divide by the cost per square yard:
375 / 15 = 25
The answer is 25 square yards.
Answer:

The student to faculty ratio at a small college is 17:3 the total number of students and faculty is 740. How many faculty members are there at the college?
Answer:
111
Step-by-step explanation:
It is given that the student to faculty ratio at a small college is 17:3.
Let number of students and faculty members are 17x and 3x respectively.
It is given that total number of students and faculty is 740.
[tex]17x+3x=740[/tex]
[tex]20x=740[/tex]
Divide both sides by 20.
[tex]x=37[/tex]
Number of student [tex]=17\times 37=629[/tex]
Number of faculty members [tex]=3\times 37=111[/tex]
Therefore, there are 111 faculty members at the college.

Write an equation that would model the tile pattern above where x represents the figure number and y represents the number of tiles
The equation that would model the tile pattern above where x represents the figure number and y represents the number of tiles is y = 2x + 5.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The three figures are shown in the picture.
After analysis:
2(3) + 1 = 7
2(4) + 1 = 9
2(5) + 1 = 11
The standard form:
y = 2(x+2) + 1
y = 2x + 4 + 1
y = 2x + 5
Thus, the equation that would model the tile pattern above where x represents the figure number and y represents the number of tiles is y = 2x + 5.

Rewrite the equation for x, and express its value in terms of a. 3/a x - 4 = 20
For this case, we must clear variable "x" from the given equation, expressed in terms of "a".
We have:
3/a x-4=20
By clearing "x" we have:
Adding 4 to both sides of the equation:
3/a x = 20 + 4
Multiplying by a/3 on both sides of the equation:
x=24a/3
x=8a
So, x=8a
Answer:
x=8a

A triangle with vertices at A(0,0), B(0,4), and C(6,0) is dilated to yield a triangle with vertices at A(0,0), B(0,10) and C(15,0). The origin is the center of dilation. What is the scale factor of the dilation?
A. 1.5
B. 2
C. 2.5
D. 3
Answer:
The scale of dilation is 2.5
Step-by-step explanation:
K · ( 0, 0 ) = ( 0 , 0 )
k · ( 0 , 4 ) = ( 0 , 10 )
k · ( 6, 0 ) = ( 15, 0 )
k = 15/6 = 10/4 = 2.5
The scale of dilation is 2.5

An interior designer charges $100 to visit a site, plus $55 to design each room. Identify a function that represents the total amount he charges for designing a certain number of rooms. What is the value of the function for an input of 6, and what does it represent?
Answer:
C(r) = 100 + 55r
C(6) = $430
Step-by-step explanation:
Fixed charges = $100
Charges per room = $55
A. function that represents the total amount he charges for designing a certain number of rooms.
Let
r = number of rooms
C = Total amount charged
C(r) = 100 + 55r
The function is C(r) = 100 + 55r
B. What is the value of the function for an input of 6, and what does it represent
C(r) = 100 + 55r
When r = 6
C(6) = 100 + 55 * 6
= 100 + 330
= 430
C(6) = $430
This means that the amount charged for 6 rooms is $430
Write the polynomial in standard form, then give the leading coefficient.
Answer:
-3y^8+18y^5+10y is the standard form of the equation. The leading coeficients are -3, 18 and 10
Step-by-step explanation:
The highest power awlays goes at the beginning of the equation. In this situation the highest power is 8, followed by 5 and then by 1. Usually the 1 as a power is not written. The leading coeficients are the numbers infront each term. If there is -4xy, the leading coeficient is -4.

Answer:
-80
Step-by-step explanation:
5×(-6 - 10)

solve by using BODMAS rule
Answer: -80
First step is to calculate everything inside the brackets = [3× (-2) -10] = [(-6) - 10] = [(-16)] then we now multiply the number outside the brackets with the number inside the brackets which = 5[-16] = -80.

Answer: d(A,B)=
Simplify your answer. Type an exact answer...
Answer:
The answer is 10 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A(7-5); B(7,5)
The distance between them is
[tex]d = \sqrt{ ({7 - 7})^{2} + ({ - 5 - 5})^{2} } \\ = \sqrt{ {0}^{2} + ( { - 10})^{2} } \\ = \sqrt{100} [/tex]We have the final answer as
